Personality traits linked to cognitive abilities.

A new study from the University of Minnesota has found surprising links between personality and cognitive abilities. The research, which synthesizes data from over 1,300 studies from the past century, representing more than 2 million participants from 50 countries, shows that active and energetic individuals tend to have a better command of various cognitive abilities, while those who experience high levels of depression or anxiety may find it more difficult to accumulate knowledge or reason logically. The study also found robust, positive relationships between many cognitive abilities and open-mindedness.
