Findings

By JOHN TIERNEY


When men and women take personality tests, some of the old Mars-Venus stereotypes keep reappearing. On average, women are more cooperative, nurturing, cautious and emotionally responsive. Men tend to be more competitive, assertive, reckless and emotionally flat. Clear differences appear in early childhood and never disappear.

What's not clear is the origin of these differences. Evolutionary psychologists contend that these are innate traits inherited from ancient hunters and gatherers. Another school of psychologists asserts that both sexes’ personalities have been shaped by traditional social roles, and that personality differences will shrink as women spend less time nurturing children and more time in jobs outside the home.

To test these hypotheses, a series of research teams have repeatedly analyzed personality tests taken by men and women in more than 60 countries around the world. For evolutionary psychologists, the bad n…

Men are more likely to be devoted and loyal husbands when they lack a particular variant of a gene that influences brain activity, researchers announced this week — the first time that science has shown a direct link between a man's genes and his aptitude for monogamy.

The finding is striking because it not only links the gene variant — which is present in two of every five men — with the risk of marital discord and divorce, but also appears to predict whether women involved with these men are likely to say their partners are emotionally close and available, or distant and disagreeable. The presence of the gene variant, or allele, also seems predictive of whether men get married or live with women without getting married.

"Men with two copies of the allele had twice the risk of experiencing marital dysfunction, with a threat of …

Excerpted from "The Athletic Prowesss of Jamaicans" by William Aiken,M.D., Jamaica Gleaner, November 22, 2006

"I wish to propose a hypothesis that addresses not only the aspect of Jamaica's raw athletic talent, but also encompasses an explanation of seemingly diverse phenomena as our high incidence of prostate cancer (one study found it to be by far the highest in the world at 304 / 100,000 men / year), our high crime rate (murder capital of the world status earlier this year), our high road traffic accident and fatality rate, and our alleged high levels of promiscuity.

What do these seemingly disparate phenomena, characteristic of Jamaican life, have in common? On close examination these phenomena are manifestations of high levels of aggressiveness and drive, high libidos, highly efficient muscles from persons of lean body mass and black ethnicity. On closer scrutiny all of these phenomena are either related to high circulating levels of testosterone or alternative…

Feminism and Freedom

Thomas Carlyle has ascribed the insights of genius to "cooperation with the tendency of the world."

“It is time to leave the question of the role of women in society up to Mother Nature--a difficult lady to fool. You have only to give women the same opportunities as men, and you will soon find out what is or is not in their nature. What is in women's nature to do they will do, and you won't be able to stop them. But you will also find, and so will they, that what is not in their nature, even if they are given every opportunity, they will not do, and you won't be able to make them do it.”

-Clare Boothe Luce, a conservative feminist who in her heyday in the 1940s was a popular playwright and a member of the U.S. Congress,

We know from common observation that women are markedly more nurturing and empathetic than men. The female tendency to be empathic and caring shows up very early in life. Female infants, for example, show greater distress and concern than male infant…
