According to a recent study, men born in the winter have a higher chance of being left-handed. But what exactly does that prove?

Via ScienceDaily:

Men born in November, December or January are more likely of being left-handed than during the rest of the year. While the genetic bases of handedness are still under debate, scientists at the Faculty of Psychology, University of Vienna, obtained indirect evidence of a hormonal mechanism promoting left-handedness among men.

Psychologist Ulrich Tran and his colleagues published their findings in the scientific journal Cortex.

Various manual tasks in everyday life require the use of the right hand or are optimized for right-handers. Around 90 percent of the general population is right-handed, only about 10 percent is left-handed. The study of Ulrich Tran, Stefan Stieger, and Martin Voracek comprised two large and independent samples of nearly 13,000 adults from Austria and Germany.

Why Is Nearly Every President Left Handed?

3Did you know that being left-handed is basically a requirement to hold the U.S. presidency? Lefties comprise just 10 percent of the population, yet the only right-handed president over the past three decades was George Dubya Bush. What does it mean? Are the left-dominant a superior race? Is the “evil” hand some sort of Illuminati-approved symbol? Via Wikipedia:

As of 2012, four (five if Reagan is counted) out of the last seven presidents have been left-handed. In the 1992 election, all three major candidates – George H. W. Bush, Bill Clinton and Ross Perot – were left-handed. The 1996 election also involved three left-handed candidates: Clinton, Perot, and Bob Dole, who learned to use his left hand after his right hand was paralyzed by a World War II injury. Additionally, both major-party candidates in the 2008 presidential election – Barack Obama and John McCain – were left-handed.

According to Daniel Geschwind, a professor of human genetics at UCLA: “[The phenomenon] is statistically significant, and probably means something.”

Left-Handed? You May Be Truly Different …

Via ScienceDaily:
We like to think of ourselves as rational creatures, absorbing information, weighing it carefully, and making thoughtful decisions. But, as it turns out, we're kidding ourselves. Over the past few decades, scientists have shown there are many different internal and external factors influencing how we think, feel, communicate, and make decisions at any given moment. One particularly powerful influence may be our own bodies, according to new research reviewed in the December issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science. Cognitive scientist Daniel Casasanto, of The New School for Social Research, has shown that quirks of our bodies affect our thinking in predictable ways, across many different areas of life, from language to mental imagery to emotion ...
