Signs that you are more intelligent than you think

Are you a genius but don't know it? Chances are you're not! However, there are a number of traits that have been scientifically proven to be associated with high levels of intelligence – and they could apply to you too.

Problems with insomnia

If you suffer from insomnia or have various sleep problems, just remember that sleepless nights are correlated with high levels of intelligence: the need for hours of sleep decreases as intelligence increases.

Various studies show that people who prefer to stay awake at night score higher intelligence scores than others.

Monogamy in men

One study demonstrates a correlation between high intelligence and a low number of sexual partners for men. However, another theory suggests that geniuses deviate from the norm.

This means that if an ordinary male is 'designed' to be polygamous and pass on his genes to his offspring, intelligent males are against this routine.

Sharjah

A study this year by Language Sciences found that people who swear are generally more fluent and have a larger and better vocabulary than others - traits traditionally associated with intelligence.

The study has debunked the previous myth that using taboo words means lacking better vocabulary.
