5.Happiness
4.Eccentricity
Eccentricity is a difficult quality to define and measure. It is usually seen as odd behaviour with regard to social norms, but behaviour which at the same time – unlike insanity – is not necessarily harmful to the individual. Some evidence (mostly anecdotal) points to creative intellectuals being prone to eccentricity, but eccentricity is also prevalent among academics. Montaigne once wrote that "obsession is the wellspring of genius and madness" – and perhaps it is this very obsession which creates an eccentric, and gifts him with a corresponding intelligence.
3.Drinking
Some studies have followed British children as they grow up, and have measured a number of characteristics. This has allowed a range of traits to be correlated to intelligence. One study looked at the link between alcohol consumption and intelligence. It was found that you could predict a child's level of alcohol intake, based on their intelligence. Surprisingly, intelligent children were more likely to be heavy drinkers when they grew up. Similar results have been observed in the United States.
2.Bipolar Disorder
Madness has been linked to intelligence since ancient times. Today, politically incorrect terms like madness are unacceptable for descriptive use, but the relation of mental illness and intelligence remains a fruitful area of study for neuroscientists and psychologists. A Swedish study compared the relationship between student performance and their mental health in later life. It found that amongst those students in the highest performing group, bipolar disorder was four times more likely to develop later in life.
1.Chocolate consumption
Correlation does not necessarily imply causation. When a surprising link is made between two seemingly unrelated factors, you have to consider what may be the real link between the two. Very recently a study looked at the number of Nobel laureates per ten million people in a country's population, and the amount of chocolate that the whole country consumes. The resulting graph shows a very strong and statistically significant positive correlation. While it may not guarantee you get a phone call from Stockholm, it seems that having a bar of chocolate – or being surrounded by chocolate-munching friends – won't do your brain too much harm in the long run.
