Just have a look at this, the stanford Prison Experiment:

As I'm reading this I could only think of the vault experiments.... and how horrible it must have been.

I read a bit about this, its pretty crazy stuff.

That's a good idea for a Vault too/

Pretty creep stuff.

So these guys apparently got "too into" their roles after only six days?

Wow, that's some messed up stuff, sounds like something from a tv series... a creepy evil one.
