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.

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?

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

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

Human behavior is incredibly pliable, plastic.

I started studying shyness in adults in 1972. Shyness operates at so many different levels. Out of that research came the Stanford shyness clinic in 1977.

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

Academic success depends on research and publications.

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

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

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

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.

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.

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

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.

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

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.

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

Evil is knowing better, but willingly doing worse.

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.

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.

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.

Bullies are often people who are shy and can't make friends easily, so, as the theme of the movie 'A Bronx Tale' tells us, it is better to be feared if you can't be loved.

Bullies may be the perpetrators of evil, but it is the evil of passivity of all those who know what is happening and never intervene that perpetuates such abuse.

I'm saying to be a hero is means you step across the line and are willing to make a sacrifice, so heroes always are making a sacrifice. Heroes always take a risk. Heroes always deviant. Heroes always doing something that most people don't and we want to change - I want to democratise heroism to say any of us can be a hero.

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.'

Many cults start off with high ideals that get corrupted by leaders or their board of advisors who become power-hungry and dominate and control members' lives. No group with high ideals starts off as a 'cult'; they become one when their errant ways are exposed.

Most of the evil of the world comes about not out of evil motives, but somebody saying 'get with the program, be a team player;' this is what we saw at Enron, this is what we saw in the Nixon administration with their scandal.

That human behavior is more influenced by things outside of us than inside. The 'situation' is the external environment. The inner environment is genes, moral history, religious training.

There are times when external circumstances can overwhelm us, and we do things we never thought. If you're not aware that this can happen, you can be seduced by evil. We need inoculations against our own potential for evil. We have to acknowledge it. Then we can change it.

When someone is anonymous, it opens the door to all kinds of antisocial behavior, as seen by the Ku Klux Klan.

A good cult delivers on its promises. A good cult nourishes the needs of its members has transparency and integrity and creates provisions for challenging its leadership openly. A good cult expands the freedoms and well being of its members rather than limits them.

I sometimes lie awake at night trying to think of something funny that Richard Nixon said.

To me, every hour of the day and night is an unspeakably perfect miracle.

I'm looking forward to providing the men of Seattle with an evening where they can kick back, light up a cigar and enjoy a night to themselves. Women, we can't technically keep you out, but please stay at home.

Prayer: the key of the day and the lock of the night.

I knew that my staying up would not change the election result if I were defeated, while if elected I had a hard day ahead of me. So I thought a night's rest was best in any event.

Tomorrow night is nothing but one long sleepless wrestle with yesterday's omissions and regrets.

You know, nobody eats in England. Three or four pints of English beer a night fills you. I can't say I'm very impressed with the food in America. it's all sort of bland. Like turkey sandwiches.

I wanted to do an episode about Chuck having a gambling problem. I wanted to portray my addiction on the show. But I think it's a little edgy for Saturday night.

What can you conceive more silly and extravagant than to suppose a man racking his brains, and studying night and day how to fly?

On that road of the informer, it is always night. I cannot ever inform against anyone without feeling something die within me. I inform without pleasure, because it is necessary.

We did a different show every night. We'd open a show, and then two weeks later we'd open the next show. And two weeks later we'd open the third show until we had all eight running. And it was just one of the richest experiences I'd ever had in my theatrical life.

I hate leaving home. I love what I do, but I'd love to go home every night.

I was babysitting the night High School Musical premiered last year. I watched with the kids and we sang along to the lyrics. I was making $12 an hour.

The name Air Supply sort of came from nowhere. I get a lot of my things in dreams and I just had a dream about it one night, and I woke up and said that's just got to be the name. That was in 1975.
