Cool experiments confirming social pressure's role in bias:
Monkey version (Potentially fictional)
Human version (Asch's Conformity Experiment)
They're not exactly the same but they both demonstrate how the society makes people decide irrationally or dishonestly. Related to what I wrote about the "biggest obstacle" and the approach to 9/11 conspiracy theories. And also to the whole HIV/AIDS debate of course, to all the "good germans" in the AIDS research field, even if they are right...
