People are less likely to make the fundamental attribution error if:

This can be reduced if people suspect and take into consideration possible external factors or are motivated to use more effort in accurately viewing the situation. This stems from the knowledge that Fundamental Attribution Error or the Correspondence Bias (though some psychologists think they should not be used interchangeably) means that you are undeservedly explaining persons behavior by some internal factors (character or intention) instead of outside, external factors but when you do the same thing you will explain it by external factors. For example, if a person A is cut off in traffic by person B, the person A will think it is because person B is mean, selfish or something similar instead of taking into consideration that he maybe had to make the green light or his wife was giving birth or he was late. If a person A did that they would look at the external factors like being late and not because they are bad at driving or an unpleasant person. So basically you need to be more considerate and try to understand why would someone do something instead jumping to conclusions.

answer; (cognitive   dissonance);

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.
