Why smart people still make irrational decisions
자주 묻는 질문
While IQ measures intelligence through standardized tests, rationality involves the ability to make sound decisions and avoid errors in judgment. Research indicates that the correlation between intelligence and rational thinking is surprisingly weak, typically falling between 0.20 and 0.35. This gap explains why individuals with high IQs or those labeled as gifted can still make bafflingly irrational choices in their professional and personal lives.
Dysrationalia is a concept used to describe the inability to think and behave rationally despite possessing adequate or even superior intelligence. It highlights a specific cognitive disconnect where a person’s measurable IQ does not protect them from significant lapses in logic. Understanding dysrationalia helps explain why brilliant scientists or high-achieving executives might fall for scams or cling to failing projects despite clear data to the contrary.
In the modern era, the cost of irrationality is higher than ever because it directly impacts critical life outcomes. Failure to think rationally can influence whether a physician selects the correct medical treatment, how a parent views life-saving medicine, or how an individual manages their financial future. Moving beyond a single intelligence score to focus on rational thinking is essential for navigating the complex decisions required in today's world.
