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

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?

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.

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.

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.

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.

Spry is not a look, spry is behavior.

Behavior is the mirror in which everyone shows their image.

The civilizing process has increased the distance between behavior and the impulse life of the animal body.

Beauty set up distance between other people and me. It warped their behavior.

I try as best I can to enter the realm of nuances of human behavior.

I'm always looking, as an actor, for activities. I think it's far more interesting to watch what people do than what they say. You always want to watch behavior, because the dialogue as written by our illustrious leaders is great. Eminently playable.

The mind cannot support moral chaos for long. Men are under as strong a compulsion to invent an ethical setting for their behavior as spiders are to weave themselves webs.

No matter how calmly you try to referee, parenting will eventually produce bizarre behavior, and I'm not talking about the kids. Their behavior is always normal.

You can't legislate or litigate good, healthy behavior but we must be willing to educate people at an early age about the affects of unhealthy living.

The orbs create feedback loops that can influence either personal of employee behavior.

Many working mothers feel guilty about not being at home. And when they are there, they wish it could be perfect. This pressure to make every minute happy puts working parents in a bind when it comes to setting limits and modifying behavior.

You were saying that once when visiting Yale, you were struck that unlike Pound, Williams's thinking was volatile, I mean, did not stay locked into a pattern of concepts that then defined his subsequent necessary behavior, whereas Pound did.

We must consider the distinctive characters and the general nature of plants from the point of view of their morphology , their behavior under external conditions, their mode of generation, and the whole course of their life.

I have always had school sickness, as others have seasickness. I cried when it was time to go back to school long after I was old enough to be ashamed of such behavior.
