549 men and women were quizzed to rate their levels of jealousy. The Spanish and Dutch researchers found that while most men felt insecure about rich, attractive, and strong rivals, but shorter men had higher levels of jealousy. Both short and tall women exhibited higher levels of jealousy where women of average height appeared more secure.

So what in the world does height have to do with jealousy? Scientists state that height is one of the first things human notice about each other and is therefore associated with status. Previous research has shown that taller men are more likely to be successful in their careers and earn more money in their lifetime.
