One reason that personality is such an important psychological concept is because of what it tells us about the kind of lives we’re likely to lead. For example, if you are very conscientious then you’re more likely to enjoy good physical health and more harmonious relationships; extraverts are happier; highly neurotic people experience more mental health problems; open-minded people command higher earnings; and, just as you’d expect, more ‘agreeable’ people are also usually popular and have lots of friends.
While it goes without saying, for instance, that extraverts are more likely to go to parties and that conscientious people are less likely to be tardy, you might not have anticipated that extraverts also spend more time luxuriating in hot tubs or that conscientiousness goes hand in hand with reading fewer books.
The researchers, Benjamin Chapman at the University of Rochester and Lewis Goldberg at the Oregon Research Institute, profiled nearly 800 people in Oregon, USA, most of whom were white, and their average age was 51. The personality test asked participants to rate how accurately 100 different trait adjectives described their personalities, including words such as bashful, kind, neat, relaxed, moody, bright and artistic. The researchers then compared these personality test scores with the same participants’ answers, recorded four years later, to how often they had performed 400 different activities over the last year, from reading a book to singing in the shower.
As well as wallowing more in hot tubs, extraverts apparently spent more time planning parties, drinking in bars, discussing ways to make money, talking on the phone while driving, decorating, and trying to get a tan (though not all at once). Greater conscientiousness, in contrast, was distinguished by the avoidance of various activities, including such innocuous pastimes as reading (which Chapman and Goldberg speculated may be seen by the highly conscientious as a leisure-time luxury), swearing and chewing on a pencil.
People scoring high on agreeability, meanwhile, said they spent more time doing ironing, playing with children and washing the dishes – presumably because their strong motivation to keep other people happy means they’d rather do the chores than have domestic acrimony. More surprisingly, they were also more likely to sing in the shower or the car.
Neurotic folk, meanwhile, engaged more often in activities that are associated with helping reduce mental distress, such as taking more tranquilisers and anti-depressants. But they also admitted to more anti-social behaviours, such as losing their temper more often, or making fun of others – perhaps because they struggle to keep their own emotions in check. Finally, open-mindedness went together with some obvious behaviours like reading poetry, going to the opera, smoking marijuana and producing art, but also some less obvious, like swearing around others, eating spicy food at breakfast, or lounging around the house with no clothes on. (To be precise, the highest scorers said they were about twice as likely to have sat around in the nude for more than 15 times in the past year, compared to the lowest scorers.) They were also less likely to follow a sports team.
