I remember in high school watching some educational film produced in the 60s where they were trying to measure how attentive drivers needed to be as a function of vehicle speed and how many other cars there were on the road. They did this by having people drive (in some cases on a busy highway at highway speeds) while wearing an apparatus that at some interval would fully obstruct their vision.
Scientists used to be able to do all kinds of crazy shit.

The Milgram and Zimbardo experiments would be vastly illegal today and they are probably the most famous studies in the field's history.
They aren't entirely conclusive and the studies had massive problems, but they laid amazing foundation we can never followup on.
