In the name of science

If you're referring to Zimbardo's experiment, the results would probably not of changed. The testers chose 24 out of 70 who were the most psychologically stable and healthy, aka resolute.

That's cuz they probably knew that the unstable would break down faster and the test was designed to be a length that even for the resolute, the length didn't happen.

There's some controversy on Zimbardo's experiment on what the purpose of the experiment was other than to harass it's subjects.

Anyways, let's say you're an experimenter. Why would you deviate from the sample that most accurately represents the population other than to keep your experiment alive (which in most cases, won't be necessary)?

What do you think my poll results would be if I had told the users the purpose of my experiment?
