There might be some truth to the old “ fake it ' til you make it ” adage after all . Research show that “ proxy of expertise”—the trait we typically affiliate with experience , like confidence — can trick our brains into consider someone knows their stuff , even if they do n’t .

This is a form of unconscious preconception , and although these “ mental leaps ” help our brains sift through a peachy deal of data and make determination more quick , they can also lead to afflicted judgement , asThe New York Timespoints out .

According to a study by researcher at the University of Utah , oftentimes when we ’re trying to resolve whose judgement to believe , how people talk or stage themselves has capital sway over our opinion than their actual noesis or qualification . trait like authority and extraversion can easily be false for expertness .

There are many differentformsof unconscious bias , and while some sort can lead to coarse opinion even when it ’s undue , other forms can have the paired essence . One such shape , call the Halo Effect , is when we let someone ’s overconfident attributes befog our mind to such a academic degree that we look across their flaws . Say , for case , you admire someone who just won a honored award , but you overlook poor conclusion they made in other area of their life . The opposite of this is the Horns Effect — when we only see their faults .

Although these unconscious prejudice are hard to overcome , being aware of them helps prevent them from having undue influence over your decision - making .
