Your brain got hardwired to make some automatic choices.
These decisions kept humans alive for thousands of years. Save mental energy and allows for quick thinking. Your brain makes predictions about future events, then acts. You only have second thoughts when the expectation of your predictive mind do not occur. (source)
Psychologists now know human brains got hardwired to dismiss facts against their views. Humans only seek and remember information they already know. They will ignore information that differs from their beliefs. Psychologists call this confirmation bias. (source)
A recent study by Michael Frank suggests confirmation bias has a genetic element. The research included 70 participants whose genotypes got analyzed. Researchers assessed the different models of the CMOT gene. This gene affects how much a person sticks with misleading advice. (source)
The participants played a game unfamiliar to English speakers. Some got the wrong advice about the symbols of the game. Then experience taught them the advice was incorrect. The group with T alleles COMT gene ignored the wrong advice 70% of the time. Participants with another form of the COMT gene, ignored the advice 50% of the time. Thus, your genes influence how gullible you are to believing misleading advice. (source)
