No middle ground

The University of Edinburgh released a study that measured the intelligence of adult brothers and sisters and found no significant difference in the average IQ between the sexes.
However, they did find that men are twice as likely to be at the top and bottom tiers of the IQ scale.

As a man, I’m not sure how I feel about this.

Personally, I know that my thoughts, speech, and actions reflect of my rapidly  shifting position to the top or bottom tiers of of the intelligence scale. I can feel either incredibly brilliant or remarkably stupid depending on the situation.

Actually, that’s not quite right. In truth, I typically consider myself incredibly brilliant regardless of the situation and only discover later that I was acting like a complete moron.

Of course, my initial, and oftentimes false, inclination to assume that I am a genius might make me stupid regardless of the results of my actions.

See?

This is why we are twice as likely to occupy the top and bottom tiers of the IQ scale.
