Early one Halloween evening, Frank's friends asked him to join them in smashing their neighbors' decorative pumpkins. He complied. Later that night, he was surprised by his own failure to resist them when they encouraged him to throw eggs at passing police cars, for which he was caught and punished. Frank's experience best illustrates the:

foot-in-the-door phenomenon.

Explanation:

In psychology, foot in the door phenomenon refers to a situation that make people becomes more likely to agree to fulfill bigger request after previously fulfilling smaller request.

This happen because after fulfilling a small request, most people developed a positive feeling from the experience of helping others. It make us feel good and somehow valuable. When we're asked to fulfill bigger request under this emotional condition, we become more likely to agree with it.

This is what happened in the example above. First, the friends ask to smash neighbor's decoration (smaller request). After that, he became more likely to agree to throw eggs at police cars (bigger request)

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
