The article mentions the marshmallow experiment.

I wonder if it's "inverse" has been studied. Promise the child another one after 15 minutes but then either not deliver on the promise or even steal the one marshmallow.

I know people that had the equivalent happen to them as kids, and I think it had enormous effect on their personality as adults.

Depending how often it happens, I wouldn't be surprised if that's how you raise sociopaths.
