Not happy with your salary? Your smartness could be the reason behind less pay, says a study

A research, published in the European Sociological Review in January, found that higher general intelligence can only increase your salary up to a threshold of about $57,300 a year. Beyond this, the study found that ability plateaus as wages continue to rise. And earners in the top 1% score slightly worse than those in the income tier directly below them.
