I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures. Why do good people sometimes act evil? Why do smart people sometimes do dumb or irrational things?

Evil is knowing better, but willingly doing worse.

What troubles me is the Internet and the electronic technology revolution. Shyness is fueled in part by so many people spending huge amounts of time alone, isolated on e-mail, in chat rooms, which reduces their face-to-face contact with other people.

I was discriminated against because I was Jewish, Italian, black and Puerto Rican. But maybe the worst prejudice I experienced was against the poor. I grew up on welfare and often had to move in the middle of the night because we couldn't pay the rent.

Prejudice and discrimination have always been a big part of my life. When I was 6, I got beat up and called dirty Jew boy because they thought I looked Jewish.

My early childhood prepared me to be a social psychologist. I grew up in a South Bronx ghetto in a very poor family. From Sicilian origin, I was the first person in my family to complete high school, let alone go to college.

What happens when good people are put into an evil place? Do they triumph or does the situation dominate their past history and morality?
