How to test consistency through your own psychology experiments

If you need to conduct some kind of experiment for a psychology course, herd experiment may be an interesting project idea. Learn more about herd psychology and explore some herd experiment ideas you might want to consider.


In the 1950s, psychologist Solomon Asch conducted a series of experiments called Asch consistency experiments, which proved the influence of social pressure on individual behavior.

In Asch’s classic experiment, participants were told that they were conducting a visual experiment. Together with a group of others, they were asked to look at three lines of different lengths and determine which line was the longest.

Then, the participants were placed in a group that they believed to include other subjects in the study. In fact, the others are actually allies in the experiment. After several trials, everyone said the correct answer, and the Allies began to choose the wrong answer.

So when other people in the group choose the wrong route as the right response, how do the real participants react?

When other people around cited the wrong answer, 75% of the subjects gave the wrong answer to at least one question about the length of the bank.

How do you think you or your peers will react in similar situations? If you are looking for a psychology experiment, you can consider creating your own variant of the Asch consistency experiment for a class.


One way to imagine your own experiment is to consider some consistency experiments that have been done in the past. Historical research and recent changes can help you better determine how you might want to conduct your own experiments.

Imagine this scenario: You are in a math class and the teacher asks a basic math question. What is 8 x 4? The teacher started asking individual students in the room for answers. You will be surprised when the first student answers 27. Then the next student answered 27. Then comes the next one!

When the teacher finally came to you, do you believe in your math skills and say 32? Or do you agree with answers that others in the group seem to think are correct?

Other versions

Conducted an integration experiment in the TV show Sneak shots It also involves a group of people on the elevator, all of them standing facing the back of the elevator. Inevitably, other people in the car will eventually face the rear, so as not to stand out from the others. A young man even turned to all directions repeatedly with others, and took off his hat when others did this.

Other consistency experiments that have been conducted include:

  • Let a group of people look up to a building
  • Picketing with blank signs and brochures for no specific reason
  • When a student leaves the classroom, when the student returns and sits down, the teacher asks everyone to stand up


Here are just some thoughts on some of the questions you can answer in your own psychology experiments:

  • How does group size affect consistency? Try to experiment with a different number of associates or assistants to understand how many others must be present before one starts to obey the team.
  • What effect does age have on consistency? Try to experiment with participants in different age groups to see if the results are different.
  • What effect does gender have on consistency? If other participants are of the same gender, are participants more likely to obey? What would happen if no other participants shared their gender?
  • How does context affect consistency? Are people more compliant in certain environments (such as classrooms) than in more natural everyday environments? Run experiments in different settings to see if there are differences.

Additional suggestions

Conducting psychology experiments in the classroom can be a bit scary. Before you start, always discuss your experimental ideas with your mentor and make sure you have the right to execute your project.

In some cases, you may need to submit your ideas in advance for review in order to obtain permission to conduct experiments with human participants.
