5 Psychological Experiments That Show Just How Dark Humanity Can Be



Those at The Idealist Revolution have compiled a list of the most notorious and most popular experiments of all time that show humanity’s dark side.


The Asch Experiment (1953)

Psychologist Solomon Asch conducted a series of experiments during the 1950’s that were designed to demonstrate the power of conformity in groups. The experiments involved a ‘vision test’ in which the subject would have to match one line with another. Unbeknownst to the subject, the other participants were assistants of the experimenter.




As the test progressed, the assistants would purposefully choose the wrong answers while the actual test subject chose the correct answer. Experimenters wanted to see how long it would take the test subject to finally conform to the rest of the group.

The results of the experiment:

  • Almost 75 percent of participants went along with the wrong answers at least once
  • After combining the results of each individual experiment, the group of participants conformed to the incorrect answer one-third of the time
  • When asked to write their response to the experiment rather than saying it out loud, participants answered correctly 98 percent of the time
  • When just one assistant (false participant) was present, there was virtually no effect on the actual participant, meaning they gave the correct answer nearly every time
  • When two assistants were present, there was a small effect on the participant
  • In the presence of three or more assistants, the effect on the participant was much greater
  • When one assistant in a group gave the correct answer, the participants level of conformity lowered dramatically

Later studies support these findings (Morris & Miller, 1975).

After the experiments were over, participants were asked why they had conformed to the rest of the group. Most responded that they didn’t want to be ridiculed, while a few actually claimed they believed the wrong answers were correct.

There are a couple problems critics have with the experiments, the first being that participants may have been motivated to avoid conflict rather than a desire to conform. The second criticism is that the experiment may not predict real world situations. However, many social psychology experts believe that even though real world situations may not be as clear-cut as in a lab, the actual social pressure to conform is most likely much greater than an individual’s will to go against the herd, indicating that in high-pressure real-life situations, a person is more likely to conform.



The Good Samaritan Experiment (1973)

This experiment comes from the Biblical story of the Good Samaritan, which is about a man (enter our Good Samaritan) who helps another man in need as the self-righteous walk on by. Psychologists John Darley and C. Daniel Batson wanted to see if religion has any effect on helpful behavior.

The psychologists had three hypotheses:

1. People thinking religious, “helping” thoughts would still be no more likely than others to offer help.

2. People in a hurry will be less likely to offer aid than others.

3. People who are religious in a Samaritan fashion will be more likely to help than those of a priest of Levite fashion. In other words, people who are religious for what it will gain them will be less likely than those who value religion for its own value or are searching for meaning in life.

The participants of this experiment first completed a questionnaire about religion (to help evaluate hypothesis #3). Next, they were instructed to walk from their current location to another building close by where they would give a speech on the Good Samaritan. The level of urgency in their instructions varied. Little did the participants know, the walk to the building itself was part of the experiment.

On the way to the other building, the participants encountered a man in an alleyway, the victim’s condition unknown. Slumped in a doorway, the man would moan and cough as they walked by. The results:

0 = failed to notice the victim as in need

1 = perceived need but did not offer aid

2 = did not stop but helped indirectly by telling an aide upon their arrival

3 = stopped and asked if the victim needed help

4 = after stopping, insisted on taking victim inside and then left him

5 = refused to leave victim, or insisted on taking him somewhere

Upon arriving at the second building, participants were then instructed to answer a questionnaire on ‘helping behavior’. “The amount of ‘hurriedness’ induced in the subject had a major effect on helping behavior, but the task variable did not (even when the talk was about the Good Samaritan).”

  • 40% offered some help to the victim
  • 63% helped in low-hurry situations
  • 45% helped in medium-hurry situations
  • 10% helped in high-hurry situations
  • 53% for helping-relevant message
  • 29% for task-relevant message

There was no correlation between “religious types” and helpful behavior, and the only variable that showed some effect was “religion as a quest”. This means that those who saw religion as a quest were less likely to offer substantial help than those who didn’t. However, later analysis shows this may not be caused by religious difference.

According to the results, a person who’s in a hurry is more likely to ignore someone who needs help, even when going on to speak about the parable of the Good Samaritan. It was noted in the study that some participants actually stepped over the victim on their way to the other building. The implication is that thinking about social norms does not imply that one will act on them when they are focused on more pressing matters.


Bystander Apathy Experiment (1968)

Similar to the Good Samaritan experiment, the Bystander Apathy experiment was also created by John Darley with the help of Bibb Latané in response to the murder of Kitty Genovese in 1964. Where the Good Samaritan experiment focuses more on the religious influences on the participant, the Bystander Apathy experiment measures how long it takes for participants to act, and whether or not they intervene at all. The results of this experiment indicate that when there is a greater number individuals present, people are less likely to help those in need.

Kitty Genovese, 28, was stabbed to death near her apartment in New York City on March 13, 1964. It had been reported that 38 individuals witnessed her murder without offering help.



While there is controversy behind how many unresponsive witnesses there actually were during Genovese’s murder, there have since been many of these experiments conducted in society, and there can be no denying that the Bystander Apathy Effect exists. Here is an experiment from 2009 conducted in the UK:


The Stanford Prison Experiment (1971)

Psychology professor, Philip Zimbardo, led a team of researchers in the Stanford Prison experiment from August 14th to August 20th of 1971. Funded by the US Office of Naval Research, the study was meant to record the psychological effects of becoming a prisoner or a guard in a prison system.




Twenty-four male students from Stanford University participated in the experiment, all of whom were given randomly assigned roles. The participants adapted to their roles better than Zimbardo could have anticipated, as the guards began to enforce authoritarian measures and subjected some of the prisoners to psychological torture.

As for the prisoners, many passively accepted the psychological abuse, and even harassed other “prisoners” at the request of the guards when they tried to prevent it. Zimbardo also found himself effected by the experiment in his role as the superintendent, ultimately permitting the abuse to continue. Two prisoners quit the experiment early and the entire study was stopped after only six days.

The results of this experiment demonstrate the impressionability and obedience of people “when provided with a legitimizing ideology and social and institutional support.” This is something the citizens of the US are now experiencing on a massive level due to the current police state.



Shortly after the study had been conducted, revolts began at both the San Quentin and Attica prison facilities.


The Milgram Experiment (1961)




Yale University psychologist, Stanley Milgram, conducted the Milgram experiments which focused on obedience to authority figures, or more specifically, it “measured the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with their personal conscience.”

The experiment began in response to German Nazi war criminal, Adolf Eichmann. Milgram designed his study to answer the question:

Was it that Eichmann and his accomplices in the Holocaust had mutual intent, in at least with regard to the goals of the Holocaust?

In other words, Milgram wanted to know if there was a mutual sense of morality among those involved. The tests suggested that the millions of accomplices to the Holocaust may have been simply following orders, despite violating their deepest moral beliefs. While the tests have consistent results, the percentages vary across the globe.

The Milgram experiments were very controversial. Many scientists considered it to be unethical and physically or psychologically abusive. Others believed it can cause permanent psychological damage as well as causing people to be less trusting in the future.

The experiment itself involved one participant (taking the role of “teacher”) asking another participant (in the role of “student”) a series of questions. The student was supposedly attached to an intimidating shock generator. The settings on the shock generator included “slight shock”, “moderate shock”, and “danger: severe shock”. The last two settings were simply labeled “XXX”.

The participants who played the role of the teacher were unaware that the participant playing the student was actually an assistant to the experimenter, and was not attached to a shock generator. In the meantime, test subjects truly believed they were delivering shocks.

The assistants who played the roles of the students would periodically plead to be released, and some complained of heart conditions. When the participants asked the experimenter if they should continue, the experimenter would give responses such as:

1. “Please continue.”

2. “The experiment requires that you continue.”

3. “It is absolutely essential that you continue.”

4. “You have no other choice, you must go on.”

The level of shock the participant delivered was used to measure their obedience, and in the end, 65 percent of the participants delivered the maximum shock level. “Of the 40 participants, 26 delivered the maximum shocks while 14 stopped before reaching the highest levels.”

  1. Sometime you have to wonder whose worse the animals in the wild or the humans in the city.And the answer is always scary.

  2. people, just remember, there have been millions of experiments on every aspect of life.
    Some for the good of humanity some not. Its up to you to think for yourselves and become better people. There will always be a chance for you to stand up and do whats right. The problem is, only a small % of you actually will..

    And these are just a few examples…

    Be better people.. Please the world depends on it..

    Thank you

  3. Wow! People are self-absorbed, conformist sheep who will do whatever they’re told as long as there’s some level of plausible deniability! If these studies were what opened your eyes to that fact you must be one of the least perceptive people in the world (or a Republican/Christian fundamentalist).

  4. There might be a sting in the tail for you
    You weirdos who hurt others
    Because you are a victim
    But you haven’t yet found the courage to
    Rise up
    Find Your Voice.
    Good luck 4 when you reach yr EPIPHANY
