“We can assume that most people, most of the time, are moral creatures. But imagine that this morality is like a gearshift that at times gets pushed into neutral. When that happens, morality is disengaged. If the car happens to be on an incline, car and driver move precipitously downhill. It is then the nature of the circumstances that determines outcomes, not the driver's skills or intentions.”

“We want to believe in the essential, unchanging goodness of people, in their power to resist external pressures, in their rational appraisal and then rejection of situational temptations. We invest human nature with God-like qualities, with moral and rational faculties that make us both just and wise. We simplify the complexity of human experience by erecting a seemingly impermeable boundary between Good and Evil.”

“It's not a question of getting more moral soldiers. Instead it's a question of recognizing how the situation of war (and the cultural institutions/practices of the military that we have designed to "prepare" people for that situation) creates monsters out of us all.”

“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.”

“The most dramatic instances of directed behavior change and "mind control" are not the consequence of exotic forms of influence, such as hypnosis, psychotropic drugs, or "brainwashing," but rather the systematic manipulation of the most mundane aspects of human nature over time in confining settings.”

“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?”

“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.”
