Avoid situations where you feel out of control orpowerless.
Avoid rejection. Rejection can dramatically reduce a person’s IQ and their ability to reason analytically, while increasing their aggression. To live in society, people have to have an inner mechanism that regulates their behaviour. Rejection defeats the purpose of this, and people become impulsive and self-destructive. You have to use self-control to analyse a problem in an IQ test, for example – and instead, you behave impulsively.
Watching movies and TV shows about stupid people and thinking about or talking to stupid people may temporarily make you stupider
Feeling powerless makes you dumber. Status expectations do affect how we interpret interruption in conversation. In general, interrupters gained in status and targets of interruption lost status. In addition, participants who were interrupted rated themselves as less influential than those who were not interrupted. As expected, interrupters, especially female interrupters, were liked less than those who did not interrupt. So interrupt people, and feel powerful! People need only feel powerful, regardless of the real power they have or their position in a hierarchy. Powerful people are more effective liars. Lies about feelings were particularly pronounced when women wanted to appear competent and when men wanted to appear likeable. This is a well-known finding: people are often found to lie more about their feelings than anything else.
The greater cognitive abilities of higher IQ tend also to be accompanied by a distinctive high IQ personality type including the trait of ‘Openness to experience’, ‘enlightened’ or progressive left-wing political values, and atheism.
