I knew there was a pony in my worrying horse****....
A propensity to worry indicates a strong ability to consider the past and future in precise detail, perhaps explaining why worriers also tend to be more intelligent.
While worriers have often been considered a liability to groups of professionals and friends alike, due to their apparent lack of confidence, they may be better at learning from past mistakes than others, and preparing for future threats.
Researchers have recently found that worriers are better at telling when others are lying and are quicker at detecting threats, such as smoke in the room caused by a fire elsewhere. Now, a survey of one hundred students at MacEwan University has shown that worrying goes hand in hand with having a higher intelligence.
