The Smoky Room Experiment: Trust Your Instincts

Picture this: you are the first person to get to class one day, so you sit alone and wait for your classmates and teacher to show up. All of a sudden, smoke starts billowing from the wall vent. You would seek help or pull the fire alarm, right? Now picture this: it is the middle of the period, and your teacher is lecturing in front of a full class. You notice smoke billowing from the wall vent, so you look around to see if anyone else sees what you see. Your classmates look at the smoke, shrug, and continue on with the lesson. Do you still seek help or pull the fire alarm, even though nobody else seems to care about the smoke coming from the vent?

Explanation

When you are alone and encounter an emergency, the pressure to take action weighs heavily on you. But what about when other people witness the emergency, too? Do you stick to your intuition and do something, or do you trust that others in the group will act accordingly or have knowledge of the circumstances that you do not? Social psychologists Bibb Latané and John Darley put this exact situation to the test in a 1968 study known as the Smoky Room Experiment.

The Smoky Room Experiment

The Smoky Room Experiment was an investigation into a phenomenon known as “diffusion of responsibility.” In the words of the study’s authors, “if an individual is alone when [they] notice an emergency, [they are] solely responsible for coping with it. If [they] believe others are also present, [they] may feel that [their] own responsibility for taking action is lessened, making [them] less likely to help.”

The Experiment

Latané and Darley hypothesized that passive behavior from other witnesses to an emergency will indicate to an individual that the event is not actually dangerous, and thus influence them not to react. A few social factors contribute to this predicted lack of action. First, individuals feel pressure to adhere to the perceived norms of the group they are in. They do not want to act in a manner contradictory to the general atmosphere of the group in order to avoid potential embarrassment. Second, people in crowds tend to behave similarly. If others in the group are behaving in a certain way, individuals within the group assume that the behavior is the norm and follow suit.

The Smoky Room Experiment tested these intuitions by placing individuals in a fake emergency situation, and with different group dynamics. In all the experimental conditions, subjects were asked to complete a survey in a room that slowly filled with smoke. The smoke was, of course, harmless, but the subjects were unaware of this. In the first experimental condition, subjects were alone in the room. These subjects were significantly more likely to report the smoke to the experimenters, and much quicker. Three-quarters of the subjects in this condition reported the smoke to the experimenters within six minutes.

The second and third experimental conditions yielded very different results. The second experimental condition involved one subject and two actors who behaved indifferently toward the smoke. When the subject noticed the smoke, the confederates simply shrugged and returned to their work, making very little conversation. Only 10% of the subjects in this condition reported the smoke. The third experimental condition involved three subjects in the room, who were all naive to the situation. Only 38% of subjects in this condition reported the smoke. Even though the room filled with so much smoke that subjects began coughing and had their vision obscured, they still refrained from reporting it when in group conditions.

Applying It

The Smoky Room Experiment sheds light on group behaviors in uncomfortable circumstances. Groups of strangers appearing to disregard emergencies is an unfortunately frequent occurrence. The media tends to attribute these situations to apathetic or callous witnesses who simply do not care to help victims. However, Latané and Darley contend that this phenomenon can be better understood by analyzing the relationships and interactions among bystanders, rather than between bystanders and victims. Witnesses of emergencies rely on social cues from other witnesses to inform their actions (or often, lack of action). The observations in their study emphasize the often detrimental power of social pressure. To reframe the results in a more positive light, the Smoky Room Experiment teaches us that sometimes it is important, perhaps even lifesaving, to trust your instincts when something goes awry.

Think Further

• How would you react in the smoky room from the experiment? Would your reaction change whether you were alone or with other people?
• Have you ever witnessed a group of people wait to react to an emergency situation until someone else does?
• Do you think the bystander effect/diffusion of responsibility observed in the Smoky Room Experiment has changed at all since the study was first conducted in 1968?

Darley and Latane hypothesized two factors that may influence bystanderism:

• Diffusion of responsibility
• Social influence
• Diffusion of Responsibility

“Someone else will help.” This is one thought that might be a result of diffusion of responsibility. To diffuse means to spread something widely, so if there are more people around the responsibility of helping is spread amongst those people so individuals feels less direct responsibility for helping. So the more people there are around to help, the less likely any will help.

• Social Influence

Humans are naturally social creatures and we’re heavily influenced by the actions of others. In situations of uncertainty, we tend to look to others for information on how to behave. Many emergency situations begin ambiguously, i.e. it is not clearly apparent that it is an emergency so we may look to others for cues. In situations where someone requires help, if other around are not helping then we may not help either.

There are two types of social influence that have been termed by social psychologists normative and informational social influence. You can read more about those here .

Supporting Studies

Smokey Room

In this experiment participants sat in a waiting room and filled out a questionnaire on life as a student. After completing two pages of the questionnaire, the room slowly filled with smoke that was puffed through an air vent. By the time the participant would have finished filling out the survey, visibility was impaired due to the smoke in the room. The results were:

• Participants alone reported the smoke 75% of the time.
• Participants in groups of 3 reported the smoke 38% of the time.
• Participants with two passive confederates reported the smoke 10% of the time.

Researcher Collapsing

In this experiment participants were again filling out a questionnaire and then as the female researcher left the room they heard a crash, the sound of a body falling and the moaning of someone in pain. The results were similar to those above.

• Alone = 70% of people helped
• Groups of 3 = 40% helped
• One passive confederate = 7% helped

Participant Collapsing

In this experiment individual participants were put in soundproof rooms with headphones and microphones. They were lead to believe that the researchers were researching about personal problems of students and that they were alone with one other student or with four other students taking part in the experiment at the same time. They were in individual rooms, so they couldn’t see the other students but could hear them through their headsets. There were actually no other participants, however, they were just tape recordings. The participants heard the recordings of the other students, the first of which said they suffered from seizures sometimes. The real participant spoke last and as they spoke, the first student was heard again and started complaining and it appeared as if they were having a seizure. They then choked and went silent.

• 85% by 2 minutes, 100% by 6 minutes
• 31% by 2 minutes, 62% by six minutes.

Take-home Messages

• The bystander effect is a social psychological phenomenon where individuals are less likely to help a victim when others are present. The greater the number of bystanders, the less likely any one of them is to help.
• Factors include diffusion of responsibility and the need to behave in correct and socially acceptable ways.
• The most frequently cited real-life example of the bystander effect regards a young woman called Kitty Genovese , who was murdered in Queens, New York, in 1964 while several of her neighbors looked on. No one intervened until it was too late.
• Notice the event (or in a hurry and not notice).
• Interpret the situation as an emergency (or assume that as others are not acting, it is not an emergency).
• Assume responsibility (or assume that others will do this).
• Know what to do (or not have the skills necessary to help).
• Decide to help (or worry about danger, legislation, embarrassment, etc.).
• Latané and Darley (1970) identified three different psychological processes that might prevent a bystander from helping a person in distress: (i) diffusion of responsibility; (ii) evaluation apprehension (fear of being publically judged); and (iii) pluralistic ignorance (the tendency to rely on the overt reactions of others when defining an ambiguous situation).
• Diffusion of responsibility refers to the tendency to subjectively divide personal responsibility to help by the number of bystanders present. Bystanders are less likely to intervene in emergency situations as the size of the group increases, and they feel less personal responsibility.

What is the bystander effect?

The term bystander effect refers to the tendency for people to be inactive in high-danger situations due to the presence of other bystanders (Darley & Latané, 1968; Latané & Darley, 1968, 1970; Latané & Nida, 1981).

Thus, people tend to help more when alone than in a group.

The implications of this theory have been widely studied by a variety of researchers, but initial interest in this phenomenon arose after the brutal murder of Catherine “Kitty” Genovese in 1964.

Through a series of experiments beginning in the 1960s and 1970s, the bystander effect phenomenon has become more widely understood.

Kitty Genovese

On the morning of March 13, 1964, Kitty Genovese returned to her apartment complex, at 3 am, after finishing her shift at a local bar.

After parking her car in a lot adjacent to her apartment building, she began walking a short distance to the entrance, which was located at the back of the building.

As she walked, she noticed a figure at the far end of the lot. She shifted directions and headed towards a different street, but the man followed and seized her.

As she yelled, neighbors from the apartment building went to the window and watched as he stabbed her. A man from the apartment building yelled down, “Let that girl alone!” (New York Times, 1964).

Following this, the assailant appeared to have left, but once the lights from the apartments turned off, the perpetrator returned and stabbed Kitty Genovese again. Once again, the lights came on, and the windows opened, driving the assaulter away from the scene.

Unfortunately, the assailant returned and stabbed Catherine Genovese for the final time. The first call to the police came in at 3:50 am, and the police arrived in two minutes.

When the neighbors were asked why they did not intervene or call the police earlier, some answers were “I didn”t want to get involved”; “Frankly, we were afraid”; “I was tired. I went back to bed.” (New York Times, 1964).

After this initial report, the case was launched to nationwide attention, with various leaders commenting on the apparent “moral decay” of the country.

In response to these claims, Darley and Latané set out to find an alternative explanation.

Decision Model of Helping

Latané & Darley (1970) formulated a five-stage model to explain why bystanders in emergencies sometimes do and sometimes do not offer help.

At each stage in the model, the answer ‘No’ results in no help being given, while the answer ‘yes’ leads the individual closer to offering help.

However, they argued that helping responses may be inhibited at any stage of the process. For example, the bystander may not notice the situation or the situation may be ambiguous and not readily interpretable as an emergency.

The five stages are:

• The bystander must notice that something is amiss.
• The bystander must define that situation as an emergency.
• The bystander must assess how personally responsible they feel.
• The bystander must decide how best to offer assistance.
• The bystander must act on that decision.

Figure 1. Decision Model of Helping by Latané and Darley (1970).

Why does the bystander effect occur?

Latane´ and Darley (1970) identified three different psychological processes that might interfere with the completion of this sequence.

Diffusion of Responsibility

The first process is a diffusion of responsibility, which refers to the tendency to subjectively divide the personal responsibility to help by the number of bystanders.

Diffusion of responsibility occurs when a duty or task is shared between a group of people instead of only one person.

Whenever there is an emergency situation in which more than one person is present, there is a diffusion of responsibility. There are three ideas that categorize this phenomenon:

• The moral obligation to help does not fall only on one person but the whole group that is witnessing the emergency.
• The blame for not helping can be shared instead of resting on only one person.
• The belief that another bystander in the group will offer help.

Darley and Latané (1968) tested this hypothesis by engineering an emergency situation and measuring how long it took for participants to get help.

College students were ushered into a solitary room under the impression that a conversation centered around learning in a “high-stress, high urban environment” would ensue.

This discussion occurred with “other participants” that were in their own room as well (the other participants were just records playing). Each participant would speak one at a time into a microphone.

After a round of discussion, one of the participants would have a “seizure” in the middle of the discussion; the amount of time that it took the college student to obtain help from the research assistant that was outside of the room was measured. If the student did not get help after six minutes, the experiment was cut off.

Darley and Latané (1968) believed that the more “people” there were in the discussion, the longer it would take subjects to get help.

The results were in line with that hypothesis. The smaller the group, the more likely the “victim” was to receive timely help.

Still, those who did not get help showed signs of nervousness and concern for the victim. The researchers believed that the signs of nervousness highlight that the college student participants were most likely still deciding the best course of action; this contrasts with the leaders of the time who believed inaction was due to indifference.

This experiment showcased the effect of diffusion of responsibility on the bystander effect.

Evaluation Apprehension

The second process is evaluation apprehension, which refers to the fear of being judged by others when acting publicly.

People may also experience evaluation apprehension and fear of losing face in front of other bystanders.

Individuals may feel afraid of being superseded by a superior helper, offering unwanted assistance, or facing the legal consequences of offering inferior and possibly dangerous assistance.

Individuals may decide not to intervene in critical situations if they are afraid of being superseded by a superior helper, offering unwanted assistance, or facing the legal consequences of offering inferior and possibly dangerous assistance.

Pluralistic Ignorance

The third process is pluralistic ignorance, which results from the tendency to rely on the overt reactions of others when defining an ambiguous situation.

Pluralistic ignorance occurs when a person disagrees with a certain type of thinking but believes that everyone else adheres to it and, as a result, follows that line of thinking even though no one believes it.

Deborah A. Prentice cites an example of this. Despite being in a difficult class, students may not raise their hands in response to the lecturer asking for questions.

This is often due to the belief that everyone else understands the material, so for fear of looking inadequate, no one asks clarifying questions.

It is this type of thinking that explains the effect of pluralistic ignorance on the bystander effect. The overarching idea is uncertainty and perception. What separates pluralistic ignorance is the ambiguousness that can define a situation.

If the situation is clear (for the classroom example: someone stating they do not understand), pluralistic ignorance would not apply (since the person knows that someone else agrees with their thinking).

It is the ambiguity and uncertainty which leads to incorrect perceptions that categorize pluralistic ignorance.

Rendsvig (2014) proposes an eleven-step process to explain this phenomenon.

These steps follow the perspective of a bystander (who will be called Bystander A) amidst a group of other bystanders in an emergency situation.

• Bystander A is present in a specific place. Nothing has happened.
• A situation occurs that is ambiguous in nature (it is not certain what has occurred or what the ramifications of the event are), and Bystander A notices it.
• Bystander A believes that this is an emergency situation but is unaware of how the rest of the bystanders perceive the situation.
• A course of action is taken. This could be a few things like charging into the situation or calling the police, but in pluralistic ignorance, Bystander A chooses to understand more about the situation by looking around and taking in the reactions of others.
• As observation takes place, Bystander A is not aware that the other bystanders may be doing the same thing. Thus, when surveying others’ reactions, Bystander A “misperceives” the other bystanders” observation of the situation as purposeful inaction.
• As Bystander A notes the reaction of the others, Bystander A puts the reaction of the other bystanders in context.
• Bystander A then believes that the inaction of others is due to their belief that an emergency situation is not occurring.
• Thus, Bystander A believes that there is an accident but also believes that others do not perceive the situation as an emergency. Bystander A then changes their initial belief.
• Bystander A now believes that there is no emergency.
• Bystander A has another opportunity to help.
• Bystander A chooses not to help because of the belief that there is no emergency.

Pluralistic ignorance operates under the assumption that all the other bystanders are also going through these eleven steps.

Thus, they all choose not to help due to the misperception of others’ reactions to the same situation.

Other Explanations

While these three are the most widely known explanations, there are other theories that could also play a role. One example is a confusion of responsibility.

Confusion of responsibility occurs when a bystander fears that helping could lead others to believe that they are the perpetrator. This fear can cause people to not act in dire situations.

Another example is priming. Priming occurs when a person is given cues that will influence future actions. For example, if a person is given a list of words that are associated with home decor and furniture and then is asked to give a five-letter word, answers like chair or table would be more likely than pasta.

In social situations, Garcia et al. found that simply thinking of being in a group could lead to lower rates of helping in emergency situations. This occurs because groups are often associated with “being lost in a crowd, being deindividuated, and having a lowered sense of personal accountability” (Garcia et al., 2002, p. 845).

Thus, the authors argue that the way a person was primed could also influence their ability to help. These alternate theories highlight the fact that the bystander effect is a complex phenomenon that encompasses a variety of ideologies.

Bystander Experiments

In one of the first experiments of this type, Latané & Darley (1968) asked participants to sit on their own in a room and complete a questionnaire on the pressures of urban life.

Smoke (actually steam) began pouring into the room through a small wall vent. Within two minutes, 50 percent had taken action, and 75 percent had acted within six minutes when the experiment ended.

In groups of three participants, 62 percent carried on working for the entire duration of the experiment.

In interviews afterward, participants reported feeling hesitant about showing anxiety, so they looked to others for signs of anxiety. But since everyone was trying to appear calm, these signs were not evident, and therefore they believed that they must have misinterpreted the situation and redefined it as ‘safe.’

This is a clear example of pluralistic ignorance, which can affect the answer at step 2 of the Latané and Darley decision model above.

Genuine ambiguity can also affect the decision-making process. Shotland and Straw (1976) conducted an interesting experiment that illustrated this.

They hypothesized that people would be less willing to intervene in a situation of domestic violence (where a relationship exists between the two people) than in a situation involving violence involving two strangers. Male participants were shown a staged fight between a man and a woman.

In one condition, the woman screamed, ‘I don’t even know you,’ while in another, she screamed, ‘I don’t even know why I married you.’

Three times as many men intervened in the first condition as in the second condition. Such findings again provide support for the decision model in terms of the decisions made at step 3 in the process.

People are less likely to intervene if they believe that the incident does not require their personal responsibility.

Critical Evaluation

While the bystander effect has become a cemented theory in social psychology, the original account of the murder of Catherine Genovese has been called into question. By casting doubt on the original case, the implications of the Darley and Latané research are also questioned.

Manning et al. (2007) did this through their article “The Kitty Genovese murder and the social psychology of helping, The parable of the 38 witnesses”. By examining the court documents and legal proceedings from the case, the authors found three points that deviate from the traditional story told.

While it was originally claimed that thirty-eight people witnessed this crime, in actuality, only a few people physically saw Kitty Genovese and her attacker; the others just heard the screams from Kitty Genovese.

In addition, of those who could see, none actually witnessed the stabbing take place (although one of the people who testified did see a violent action on behalf of the attacker.)

This contrasts with the widely held notion that all 38 people witnessed the initial stabbing.

Lastly, the second stabbing that resulted in the death of Catherine Genovese occurred in a stairwell which was not in the view of most of the initial witnesses; this deviates from the original article that stated that the murder took place on Austin Street in New York City in full view of at least 38 people.

This means that they would not have been able to physically see the murder take place. The potential inaccurate reporting of the initial case has not negated the bystander effect completely, but it has called into question its applicability and the incomplete nature of research concerning it.

Limitations of the Decision-Helping Model

Schroeder et al. (1995) believe that the decision-helping model provides a valuable framework for understanding bystander intervention.

Although primarily developed to explain emergency situations, it has been applied to other situations, such as preventing someone from drinking and driving, to deciding to donate a kidney to a relative.

However, the decision model does not provide a complete picture. It fails to explain why ‘no’ decisions are made at each stage of the decision tree. This is particularly true after people have originally interpreted the event as an emergency.

The decision model doesn’t take into account emotional factors such as anxiety or fear, nor does it focus on why people do help; it mainly concentrates on why people don’t help.

Piliavin et al. (1969, 1981) put forward the cost–reward arousal model as a major alternative to the decision model and involves evaluating the consequences of helping or not helping.

Whether one helps or not depends on the outcome of weighing up both the costs and rewards of helping. The costs of helping include effort, time, loss of resources, risk of harm, and negative emotional response.

The rewards of helping include fame, gratitude from the victim and relatives, and self-satisfaction derived from the act of helping. It is recognized that costs may be different for different people and may even differ from one occasion to another for the same person.

Accountability Cues

According to Bommel et al. (2012), the negative account of the consequences of the bystander effect undermines the potential positives. The article “Be aware to care: Public self-awareness leads to a reversal of the bystander effect” details how crowds can actually increase the amount of aid given to a victim under certain circumstances.

One of the problems with bystanders in emergency situations is the ability to split the responsibility (diffusion of responsibility).

Yet, when there are “accountability cues,” people tend to help more. Accountability cues are specific markers that let the bystander know that their actions are being watched or highlighted, like a camera. In a series of experiments, the researchers tested if the bystander effect could be reversed using these cues.

An online forum that was centered around aiding those with “severe emotional distress” (Bommel et al., 2012) was created.

The participants in the study responded to specific messages from visitors of the forum and then rated how visible they felt on the forum.

The researchers postulated that when there were no accountability cues, people would not give as much help and would not rate themselves as being very visible on the forum; when there are accountability cues (using a webcam and highlighting the name of the forum visitor), not only would more people help but they would also rate themselves as having a higher presence on the forum.

As expected, the results fell in line with these theories. Thus, targeting one’s reputation through accountability cues could increase the likelihood of helping. This shows that there are potential positives to the bystander effect.

Neuroimaging Evidence

Researchers looked at the regions of the brain that were active when a participant witnessed emergencies. They noticed that less activity occurred in the regions that facilitate helping: the pre- and postcentral gyrus and the medial prefrontal cortex (Hortensius et al., 2018).

Thus, one’s initial biological response to an emergency situation is inaction due to personal fear. After that initial fear, sympathy arises, which prompts someone to go to the aid of the victim. These two systems work in opposition; whichever overrides the other determines the action that will be taken.

If there is more sympathy than personal distress, the participant will help. Thus, these researchers argue that the decision to help is not “reflective” but “reflexive” (Hortensius et al., 2018).

With this in mind, the researchers argue for a more personalized view that takes into account one’s personality and disposition to be more sympathetic rather than utilize a one-size-fits-all overgeneralization.

Introduction to Who were Latane and Darley

If you witnessed an emergency, you would certainly help those in need, right? Even if you didn’t directly address the problem, if someone were in desperate need of help, you would definitely call the police or an ambulance at the very least, correct? Well, social psychology doesn’t think so. Based on Latane and Darley’s experiments on the bystander effect, your likelihood of helping a person in an emergency is highly dependent on the number of people around you at that moment. The bystander effect is an important social behavior from which we can learn a lot for periods of crisis, and it helps us understand human behavior for groups of people. Therefore, it is important to understand the bystander effect, its causes and possible counteractions for the Advanced Placement (AP) Psychology exam.

Would You Help Kitty Genovese?

New York, March 13, 1964. A woman named Catherine Susan Genovese, commonly known as Kitty Genovese, is stabbed, robbed, sexually assaulted and murdered on the street by a man named Winston Moseley. The tragedy lasted for approximately thirty minutes, during which Kitty Genovese screamed for help. The lights on the nearby apartments went on and off, neighbors heard her screaming, watched from the windows and not one of the thirty-eight witnesses called the police.

If this were a scene from a thriller book, it would sound non-realistic. The editor of the book would probably look straight at the author and protest, “You can’t put a bunch of witnesses on a thirty-minute crime and have none of them lift a finger to help! No reader would believe this!”

This is why the murder of Kitty Genovese shocked the population in 1964. We like to think we are mostly good, ethical and altruistic individuals who would never refuse to help someone in an emergency. At the time, professors and preachers tried to explain this apparently horrifying indifference and lack of intervention with reasons such as “moral decay,” “alienation” and “dehumanization produced by the urban environment.” Social psychology researchers Bibb Latane and John Darley , however, had another hypothesis.

Their hypothesis was that when we are in the presence of other people, we are less likely to intervene in an emergency. Why? What happens? What’s so different between being alone and being in a group when a problem occurs? This is what Latane and Darley explored in their experiments on bystander effect, a critical discovery in the field of social psychology .

The Experiments

In 1968, Latane and Darley created a situation similar to that of Kitty Genovese’s (but without violence)to understand what social forces were acting on the day of the crime.

In the first experiment, Latane and Darley recruited college students to participate in what seemed to be an innocent talk with other college students. Each participant was given headphones and a microphone and stayed alone in a room, talking to other students through the intercom. According to the researchers, this was done to protect everyone’s anonymity. The theme of the conversation was college life problems, worries and the like.

Next, Latane and Darley divided the participants into three groups:

• The first group thought they were talking one on one with the other person
• The second group thought they were talking with two other people
• The third group thought they were talking in a group of five people

In a certain point of the conversation, a person in the intercom started acting as if he was having a seizure and asked for help. Latane and Darley wanted to investigate the difference of behavior between each group, according to the number of witnesses. These were the results:

• When participants thought they were the only ones who could help, 85% of them left the room and asked for assistance
• When participants thought there were other two bystanders with them, that number dropped to 64%
• In the situation with four bystanders, only 31% of participants searched for help

“Well, okay,” you might say, “Maybe the number of people around you influences the likelihood of giving assistance, but if it were the participants’ own lives that were at risk, I’m sure everybody would do something regardless of the number of bystanders.”

Latane and Darley thought about that too and developed a second experiment to investigate this. How do you think that one went down?

For the second experiment, Latane and Darley once again recruited college students, this time to “fill out a questionnaire.” They divided the participants into two groups:

• Participants filling out the questionnaire alone in a room
• Participants filling out the questionnaire with many confederates in the room who were also filling out the questionnaire

A few minutes after the participants start the task, a black smoke starts to creep out from the room’s air conditioner. It gets thicker and thicker until the room is filled with smoke. However, in the second group, the confederates were instructed to ignore the smoke, and so no one seems to be bothered about it. What do you think happened?

• Of the participants who were alone, 75% quickly left the room and reported the smoke to the researchers
• Of those who were in the room with the unshaken confederates, only 10% left the room and searched for help, after twice the time of the participants who were alone

This is a surprising result that confirms the first study’s findings: the greater the number of bystanders, the less likely we are to act. Even if we ourselves could be in danger, being surrounded by people who do nothing makes us more likely also to do nothing. This opposes the intuitive idea that the more people there are in an emergency situation, the more likely it is that someone would call for help. As Latane and Darley have shown in their studies, it is quite the contrary.

Why the Bystander Effect Happens

As we have seen earlier, the bystander effect states that the likelihood of intervention is inversely related to the number of bystanders . In other words, the more witnesses there are, the less likely each one of them is to intervene in a problematic situation. But why does this happen? What can explain this?

The main reason proposed by Latane and Darley is diffused responsibility. When you are in a large group and something needs to be done, you feel less responsible for the task. There are so many people around; someone else is surely taking charge of the situation, so why should you step up? The sense of responsibility is diffused in the group, and the result is that, very frequently, no one does anything.

This is what happened in the Kitty Genovese situation. The thirty-eight neighbors witnessed the crime and saw each other through the windows. “Of course someone will call the police,” each one of them thought, “a woman is being murdered right on the street!” Unfortunately, diffused responsibility led to none of them taking action.

Another reason for the bystander effect pointed out by Latane and Darley is pluralistic ignorance . Pluralistic ignorance is what happens when you observe a situation and at first think that, for example, it is dangerous. However, people around act as if it isn’t a problem and don’t look concerned. Then, you also assume that it’s really not a big deal and that the right thing to do is just to keep doing what you’re doing and not intervene.

In the Kitty Genovese situation, the neighbors looked around to check how others were reacting, and since no one was getting desperate and fighting to help her (because of the diffused responsibility effect), they continued with their everyday lives despite her persistent cries for help.

How the Bystander Effect Happens

According to Latane and Darley, bystanders go through a 5-step cognitive and behavioral process in emergency situations:

• Notice that something is happening – many things influence our ability to notice a situation, for example, being in a hurry or being in a group in which no one notices the event.
• Interpret the situation as an emergency – this is where the pluralistic ignorance becomes a problem, especially in ambiguous situations when people aren’t quite sure of what is happening and therefore don’t act in an urgent manner.
• Assume a degree of responsibility – this is affected by the diffused responsibility phenomenon and also by other elements such as whether we see the victim as someone deserving of help, whether we see ourselves as someone capable of helping and the relationship between the victim and ourselves.
• Choose a form of assistance – this can be a direct intervention helping the victim or a detour intervention like calling the police.
• Take action – performing the assistance chosen.

Other Variables that Influence Our Likelihood to Help

Latane and Darley’s crucial studies were further investigated by other social psychologists who continued to develop the knowledge on what makes us more likely to help others and show altruistic behavior. Some of the other variables are:

• Similarity: we are more likely to help those who are in some way similar to ourselves. This can be regarding gender, ethnicity, clothes, beliefs and even the basketball team the victim happens to root for.
• Consequences: when we think there will be strong consequences for our intervention, we are less likely to act. For example, many people avoid intervening in emergency medical situations because they are afraid of giving inadequate assistance, making the situation worse and later being held responsible for it.
• Familiarity with the environment: we are more likely to intervene in situations in places we are familiar with. That can be because, for instance, we know where the emergency exits are or where to find help quickly.

How to Counter the Bystander Effect

Okay, so now you know the dangers of the bystander effect and why and how it happens. You might be wondering: “Is there anything we can do to avoid it? How can we increase the likelihood of helping other people?”

Fortunately, there are possible measures to counter the bystander effect and avoid future Kitty Genovese situations. After all, this is the main reason to study human behavior: not to think of our tendencies in a conformed and cynical way and make the same mistakes over and over again, but to reflect on how we can improve ourselves, our lives and our relationships. So here are a few tips to use this knowledge in our service:

• Recognize situations where the bystander effect may be present and be aware of them. Realize that we are all bystanders. By doing so, next time there is a problem you’ll be able to notice it, interpret it as an emergency and assume responsibility more clearly.
• Review your concepts about who deserves help. This can get tricky when people perceive the victim as someone who brought their unfortunate events upon themselves, like drug or alcohol addicts. No one is forced to offer assistance to everybody in need, but be aware of your own ideas and tendencies.
• Know how to help people in different situations. Seeing yourself as more qualified to give assistance raises the likelihood of that behavior.
• If you need help, choose a specific person to ask for it. This avoids the diffused responsibility phenomenon. Instead of saying “Someone call an ambulance,” point directly to someone and say “You, call an ambulance!”
• If someone needs help, be the one to take action. Once people see that somebody is intervening, they are more likely to start offering assistance as well.

A Free Response Question (FRQ) Example

Now that you’ve learned all about Latane and Darley’s bystander effect, try to answer the following FRQ from a past exam:

For each of the following pairs of terms, explain how the placement or location of the first influences the process indicated by the second:

– Presence of other, performance

There are many possible answers to this question, for example social facilitation, social loafing, conformity and the theme of this AP® Psychology review : the bystander effect. Whatever you choose, the important thing is to correctly describe the phenomenon of choice and connect the elements “presence of other” and “performance” in a clear way.

by Filed under Skeptoid Podcast #749 October 13, 2020 Podcast transcript | The event that kicked off research into the bystander effect (or bystander apathy, as it was called at the time) was the very horrible rape and murder of 28-year-old Kitty Genovese in New York in 1964. The reported that some 38 people saw or heard the attack, but that none intervened to help. This shocked the nation, and got everyone talking about bystander apathy. It made no difference at the time, but more than 40 years later, the published substantial investigative journalism that found the original article's facts were greatly exaggerated. Only a few people had seen or heard anything, few thought it was an attack, and three people did render assistance to Genovese, tragically too late. But the basic fact that some small number of earlier witnesses did know what was going on and yet did nothing still supports the idea of bystander apathy. Genovese's death did launch the field of research into this concept. Perhaps the most famous example is the Smoke Filled Room study. In 1968, a pair of social psychology researchers, Bibb Latane and John Darley, set up a series of experiments searching for an explanation for cases like the Kitty Genovese murder. Their hypothesis was that when other people are around, we're all less likely to intervene in some emergency. They did a number of different experiments. In this one, they took a room and put a row of chairs in it, and then recruited subjects to fill out some questionnaire. They divided the subjects into two groups. The first group consisted of subjects who went into the room and sat down to fill out the questionnaire — all by themselves, with nobody else in the room. But trouble was brewing. After a few quiet minutes filling out the form, ominous thick smoke began leaking into the room through a vent. Recognizing the evident danger, the vast majority of subjects immediately left the room to advise the researchers. When by themselves, they were Johnny on the Spot. Subjects in the second group, however, had a somewhat different experience. The chairs were all filled with other people also working on the same forms — and, unbeknownst to the subject, those others were all confederates who were part of the experiment. When the smoke began, the confederates' job was to ignore it. Each subject was the only person in the room who noticed or cared that they were all about to burn to death. However, perhaps thinking that those others knew better and knew the smoke wasn't a problem, or maybe that others were closer to the vent or to the door and would solve it first, the subjects almost never took any action. In the end, 75% of solo subjects intervened in the smoke, and just 10% of subjects surrounded by confederates did. The difference was astonishing, and appeared to confirm Latane and Darley's hypothesis. They attributed it to pluralistic ignorance, in which you adopt the lack of concern shown by the others around you, assuming that their lack of action means there's no need for action; and also to diffused responsibility. This is when there are so many more people around than are needed for a certain task that there's no point in you being the one to step up and do it. Everyone around is responsible, so in a sense, no one is. They did other experiments as well, including one where a subject walked down the street when a woman in distress appeared. People who were walking by themselves voluntarily offered assistance 70% of the time; but when experimenters gave the subject a stranger to walk along with them, the subjects offered assistance only 40% of the time. Having only a single other person around whose reaction the subjects were unsure of was enough to discourage intervention by the majority of subjects. Latane and Darley's paper concluded, in no uncertain terms: And thus the bystander effect entered the public body of knowledge in social psychology. A single person, or a small group, is more likely to take action than is a large group. But then in 2019, it was reported everywhere that the science underlying the bystander effect had been debunked. Researchers observed actual public conflicts in the real world and discovered that large groups of bystanders do render assistance, almost all the time. Here's a headline from : And from : And from the science news on : Even the trumpeted this shocking new development to the masses: Every indication given by the 2019 headlines was that the bystander effect had been turned on its head and disproven. Bystanders do, it turns out, spring into action and intervene; they do not apathetically look the other way in the hope that someone else will solve the problem. What this new group of researchers did was to study "public conflicts" — basically street altercations of some sort — captured by surveillance cameras. From over 1200 conflicts recorded, 300 comparable conflicts ranging from "animated disagreements" to "grave physical violence" were analyzed in urban areas of three cities: Lancaster in the United Kingdom, Amsterdam in the Netherlands, and Cape Town in South Africa, cities with greatly differing levels of violent crime. In all three places, irrespective of their normal crime level, there was equally about a 90% chance that one or more bystanders would intervene in the conflict, and that chance was highest when there were the most bystanders around. The authors wrote: Certainly this would indeed appear to overturn not only Latane and Darley but virtually every psychology school and textbook on the planet. How could the Smoke Filled Room results have been so wrong? If the other results we see are true, what could explain the observation that only 10% of the time, the smoke emergency was reported? The explanation lies in the experimental design. Taking all of these cases into consideration — whether it's Kitty Genovese, the people in the Smoke Filled Room, or the public conflicts captured by the surveillance cameras in the three cities, or any of the other countless cases where there's been an opportunity for a bystander to intervene — there is one conclusion that's apparently supported by all the data. In the great majority of such events, bystanders intervene about 80% of the time. That's a rough number, because I'm comparing all sorts of diverse data sets, but it's within 10% of the true number in all the cases studied. And that number seems to hold constant whether there is one bystander or whether there are one hundred. About 80% of victims are helped, and about 80% of other crises receive rendered assistance of whatever kind. Yet, in the Smoke Filled Room, intervention was observed only 10% of the time. Why? It's simply because . Had Latane and Darley designed their experiment better, there would have been confederates. All the people in the room would have been subjects. And if that had been the case, the data tells us that we'd have seen that 80%-or-so intervention rate. With only a single subject and half a dozen confederates, we saw the subject look around the room and consider whether to act, but she was invariably dissuaded because of all the other people around. Any one of them could have acted at any moment, for all the subject knew, and so she refrained. The way the experiment was designed was an interesting test of peer pressure, but it was a fair test of the bystander effect. By controlling the reaction of most bystanders, they broke the math. So what about Kitty Genovese? She was just unfortunate enough to be among the 20% of cases in which bystanders do not intervene. It doesn't matter whether there were 38 bystanders or just two; the 80% rule seems to hold true. About 20% of the time, a victim in plain view will not receive any help. Because of pluralistic ignorance and diffused responsibility that Latane and Darley correctly identified, each of us is individually less likely to intervene as the number of our fellow bystanders grows; but the likelihood for the group as a whole to intervene remains about the same. It was too late to help Kitty Genovese, but her death did help prompt the creation of the 9-1-1 emergency phone system. The question is whether making the task of rendering assistance as easy as dialing three digits bumps that basic 80% ratio even higher. I certainly hope so. Perhaps that's the next area of study.   Cite this article: Dunning, B. "Observing the Bystander Effect." Skeptoid Podcast. Skeptoid Media, 13 Oct 2020.

Send us your question at history@time . com and you might find your answer in a future edition of Now You Know. Nowadays, the “smoke-filled room” is mostly just a metaphor—but there was a real room that started it all. Well, sort of. The compelling image of the smoke-filled room, a “place of political intrigue and chicanery, where candidates were selected by party bosses in cigar-chewing session,” per William Safire , arose during the 1920 Republican convention. That year, Sen. Warren G. Harding of Ohio was the come-from-behind nominee for president, selected after ten ballots. According to historian David Pietrusza , author of 1920: The Year of the Six Presidents , the room in question is often credited with the phrase “because the people who come out of the room, one of them certainly brags about it, and how they put over Harding.” The storied conference took place in a room in Chicago’s Blackstone Hotel. But, Pietrusza says, that room probably gets too much credit. There were other reasons that contributed to Harding’s success. Get your history fix in one place: sign up for the weekly TIME History newsletter That year, the Republican Party came into the convention with a slew of candidates, none of whom had enough delegates to win the nomination. The initial rounds of voting showed two very evenly matched front runners for presidential nominee: Frank Lowden, Governor of Illinois and Leonard Wood, an Army general. Senator Hiram Johnson was in third place, but although he enjoyed popular support in the primaries he was too radical for many in the Republican party, having helped form the Progressive party a few years earlier. As a result of the votes being split, none of the front runners were close to securing the necessary number of delegates when the convention adjourned after its first four ballots on the evening of June 11, 1920. Many meetings took place that night but one gathering, composed primarily of Republican senators, took on mythic qualities—though the discussion was not exactly the highly orchestrated secretive conclave of party heavyweights that the phrase “smoke-filled room” has come to imply. Instead, it was a very disorganized meeting into which people could easily wander. And the meeting, at which the senators decided that they’d vote for Harding in order to break the impasse, didn’t even lead to his immediate nomination. It would take all day for his tiny incremental progress to push him into real contention on the ninth ballot, which came after another multi-hour recess. During that vote, Lowden, who had been in the lead previously, freed his delegates to vote for other candidates. Harding jumped into the lead for the first time. He won on the next ballot. “Basically the convention goes naturally to Harding because there’s nobody else,” Pietrusza explains. “[Harding biographer] Andrew Sinclair called him the available man. ” But that didn’t keep observers from guessing that something nefarious had gone on behind closed doors. In 1955, historian Wesley Bagby wrote that choosing Harding instead of any of the three leaders “led immediately to extensive speculation as to the men or forces responsible.” “Anytime you get a situation where it’s going to be close, somebody’s going to sort it out and there will be either rumors or actuality of people maneuvering in the back room,” Pietrusza agrees. There are only so many ways to resolve a deadlocked vote, and choosing an entirely different person—someone who may later seem to have come out of nowhere—is an effective option. He also notes that the idea of a dark-horse candidate, who comes from behind having never been expected to win, far predates Harding’s nomination: that’s been around since James K. Polk’s 1844 nomination, after Polk was initially a potential vice-presidential candidate. MORE: This Graphic Shows What Happened at the Last Real Brokered Convention As for the phrase itself, it’s not fully clear who first used it. At the time, newspapers frequently cited Harry Daugherty, Harding’s campaign manager and later his attorney general, as having predicted that Harding’s time would come “about eleven minutes after 2 o’clock on Friday morning at the convention, when fifteen or twenty men, somewhat weary, are sitting around a table [and] some one of them will say: ‘who will we nominate?'” as a New York Times piece from Feb. 1920 quoted him. A variation on that quote—with the crucial tweak: “around a table in a smoke-filled room”—made it into popular parlance, but Daugherty later denied having said it and probably wasn’t the actual source of the quote. Safire traces the phrase to Kirke Simpson, an Associated Press reporter who filed a story at 5 a.m. on June 12 which began “Harding of Ohio was chosen by a group of men in a smoke-filled room early today as Republican candidate for President.” Interestingly, the New York Times ran an article before Harding’s nomination about the Republican party platform having been drafted “last night by a few men in a smoke-filled room.” The description was likely factual, given the prevalence of smoking at the time, but it doesn’t have the negative connotations that quickly attached to the phrase. No matter who introduced the phrase, newspapers did emphasize the role of overnight deliberation in their initial reporting on the nomination, and the phrase and idea it conjured captured media attention as a way to understand Harding’s unexpected selection and to condemn it. The convention was called “the final breakdown of the American primary system so far as selecting presidential nominees is concerned” and one writer in Baltimore’s The Sun wrote searingly of “the smoke filled room and the sleepy Senators between 2 and 3 o’clock in the morning.” Harding’s opponent in the general election, James Cox, also disparaged the ‘smoke-filled room’ while campaigning. Harding won the presidency anyway. MORE: 25 Moments That Changed America Though smoke-filled back rooms may still be fodder for popular speculation and worry , they’re much less likely to actually make a difference in presidential nominations these days. In the years before the primary system we’re now familiar with solidified in the 1970s, brokered conventions—ones where there was a lot of maneuvering left to be done before a nominee could be agreed upon— weren’t uncommon. Generally, delegates were chosen at state conventions and were unbound, so they would do as they were told by in-state influencers. Or, non-binding “beauty contest” primaries let people express their preferences in a nonbinding way. Changes to party rules and the rise of binding primary races all contributed to the decline in the frequency of contested conventions—and in the power of the smoke-filled room.
