The left hand is the hand of presidents, boxers and great artists. That's what science says.
1. We vote for them
Barack Obama, Bill Clinton, George H. W. Bush and Gerald Ford. Four of the last seven US presidents were left-handed. That may be a coincidence, but according to a Dutch study it can be explained scientifically.
The research shows that gestures with the right hand are seen as positive and gestures with the left hand are seen as negative, writes the Huffington Post. Left-handed people benefit from this in television debates, because the image is mirrored.
2. They think out of the box
The story goes that left-handed people are more artistic than their right-handed counterparts. That is not entirely true, but there is some truth in it.
According to a study by the American Journal of Psychology, left-handed people are better at coming up with alternative solutions to problems. With a bit of goodwill you could say that they are therefore more creative.
3. You must not get into a fight with them
A French study shows that only 3 percent of the members of primitive pacifist societies are left-handed. In violent societies that is 27 percent.
According to the researchers, this is because left-handed people have an advantage in fighting. They can surprise their opponent by hitting the 'wrong' hand.
4. They are better at sports
When it comes to sports where two opponents compete against each other, left-handed people have the advantage. Most researchers agree on that. And it also appears from the fact that left-handed people are over-represented on a professional level in sports such as tennis and boxing.
One of the theories about the cause of this is that left-handed athletes play against right-handed opponents more often than vice versa. That offers them an advantage.
5. Speeches come in easier
Left-handers can hear sounds that change slowly and calmly, according to a study by the Georgetown University Medical Center in Washington, USA. That is because the right hemisphere, which controls the left hand, is better at analyzing vowels.
Speeches often sound calm and even. That is why it is easier for left-handed people to listen to it than for right-handed people, who are better able to hear consonants and rapidly changing sounds.
