Heroes are those who can somehow resist the power of the situation and act out of noble motives, or behave in ways that do not demean others when they easily can.

The Stanford prison experiment came out of class exercises in which I encouraged students to understand the dynamics of prison life.

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.

The line between good and evil is permeable and almost anyone can be induced to cross it when pressured by situational forces.

Evil is knowing better, but willingly doing worse.

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?

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.

Situational variables can exert powerful influences over human behavior, more so that we recognize or acknowledge.

At North Hollywood High School, I was shunned by everyone. I would sit down in the cafeteria, and students would get up from the table and walk away. They thought I was from the Mafia.

Academic success depends on research and publications.

After doing psychology for half a century, my passion for all of it is greater than ever.

Human behavior is incredibly pliable, plastic.

One can't live mindfully without being enmeshed in psychological processes that are around us.

There are no limits to what I would do to make my classes exciting, interesting, unpredictable.

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.

The level of shyness has gone up dramatically in the last decade. I think shyness is an index of social pathology rather than a pathology of the individual.

Time perspective is one of the most powerful influences on all of human behavior. We're trying to show how people become biased to being exclusively past-, present- or future-oriented.

Being hurt personally triggered a curiosity about how such beliefs are formed.

Careers in virtually all academic disciplines are fostered by being a superstar who knows more about one subject than anyone else in the world.

Ideas for my first experiments in human aggression came from discussions we had in a research seminar about William Golding's 'Lord of the Flies.'
