Socialising and chatting with friends, meeting up for a drink and catch-up to chew the fat, is commonly seen as something good for our mental health.
But smart people, it turns out, are better off alone.
Well, that's what researchers in a recent study are claiming, anyway.
The British Journal of Psychology claims population density and friendship can affect our happiness.
Evolutionary psychologists Kanazawa and Li have discovered, while people generally feel happier when they spend time with others, very smart people are an exception to this rule.
The psychologists say that the lifestyle of our ancient ancestors form the basis of what makes us happy in the modern era.
Their study was carried out on 15,000 adults, between the age of 18 and 28, and the results weren’t too jaw-dropping.
It turns out people who lived in more densely populated areas were less satisfied with their life in general, compared to those who live in less populated areas.
Psychologists also discovered that the more social a person is with their close friends, the greater they said their happiness was.
But - there was a key exception.
The findings, it turns out, were actually diminished - or, remarkably, even reversed - when the results of intelligent people were scrutinised.
In other words: when smart people spend time with their friends, it makes them less happy.
Researchers say this is because intelligent people can more easily adapt to their surroundings in the modern world, so they don’t need close relationships to help them with food and shelter, like our ancestors did.
Another theory put forward is that smarter people are more aspirational, and want to spend more time working towards their goals, rather than socialising.
So there we have it.
We thought that human interaction would make people happier, but it turns out intelligent people are better off alone.
