It is estimated that only about 10% to 12% of people are left-handed. Out of the seven most recent Presidents of the United States, five (Gerald Ford, Ronald Reagan, George Bush snr., Bill Clinton and Barack Obama) have been left-handed. The likelihood of that happening by chance is apparently 1 in 10,000. Left-handers have been less to the fore among British political leaders. Until David Cameron entered No. 10, there had only been two left-handed Prime Ministers: Winston Churchill and James Callaghan. We now have a third.
This may seem the basis for a trivia quiz question but it may have implications for how the country is led. People who are left-handed, according to one research study, tend to think quicker than right-handers when playing sport or computer games. Some research (though challenged) points to a correlation between left-handedness and high intelligence. Left-handers are apparently to be found in disproportionate numbers among high achievers. I have certainly noticed an above-average number of left-handers among politicians and, indeed, civil servants. (Cabinet Secretary, Sir Gus O’Donnell, is, I think, left-handed.) I tend to notice these things. But then I would.
