Les gènes de l’intelligence remis en question
Le Monde: Avec l'explosion des analyses génétiques, de nombreux travaux ont associé des variations dans plusieurs gènes impliqués dans le fonctionnement du cerveau avec le niveau d'intelligence. Prochainement publiée par la revue Psychological Science, une étude internationale revient sur ces "gènes de l'intelligence" : elle a essayé de retrouver leur lien avec le QI en utilisant trois jeux de données indépendants qui totalisent presque 10 000 personnes. En bref, ces chercheurs ont suivi le traditionnel et indispensable chemin de la science : répliquer l'expérience pour voir si l'on aboutit au même résultat. Read the full story: Le Monde

Män har uppblåsta egon
Sveriges Television: De signaler vi ger varandra när vi flörtar kan vara svårtolkade. Speciellt män läser ofta kvinnors signaler fel. I studien fick 96 manliga och 103 kvinnliga studenter gå på snabbdejt med varandra. De fick tre minuter på sig att prata med fem olika potentiella partners. Innan samtalen fick deltagarna ranka sin egen attraktionskraft och uppge hur pass intresserade de var av tillfälligt sex. Efter varje dejt fick deltagarna sen betygsätta varandra på ett antal punkter - till exempel när det gällde fysisk attraktivitet och sexuellt intresse för den andre deltagaren.

Why ugly men believe pretty women are interested in them
Evening Herald: SOME men can get by on a wink and a smile -- but those with less chiselled features make up for it with misguided optimism about their own appearance. The study could help explain the mystery of why so many men think women are interested in them when they are not, a study claims. Some men are able to snare a partner far more attractive than them through relentless persistence and overblown belief in their own sex appeal. Scientists think this may be down to an evolutionary trait which tricks men into overestimating the value of their looks to prevent them from missing a mating opportunity.

Men Think They’re Hot — And It Works
Discovery News: It's a classic tale of unrequited love: Boy meets Girl. Boy likes Girl. Girl is not really that into Boy. Totally failing to take the hint, Boy pursues Girl anyway. The storyline is common, and not just in Hollywood romance films. A new study found that men tend to overestimate how attractive they are to women, while women most often underestimate how much men want them. While the outcome of these scenarios can go either way, researchers suspect that there may be deeply rooted reasons why signals get crossed when men and women check each other out.

Relentless optimism of ugly men makes up for unappealing looks
The Telegraph: Despite being at a disadvantage in the looks department, some men are able to snare a partner far more attractive than them through relentless persistence and overblown belief in their own sex appeal. Now scientists believe this could be down to an evolutionary trait which tricks men into overestimating the value of their looks to prevent them from missing a mating opportunity. This overconfidence causes them to try their luck with a greater number of women because they are less likely to see them as unattainable.

Traumatic Experiences May Make You Tough
Your parents were right: Hard experiences may indeed make you tough. Psychological scientists have found that, while going through many experiences like assault, hurricanes, and bereavement can be psychologically damaging, small amounts of trauma may help people develop resilience. “Of course, everybody’s heard the aphorism, ‘Whatever does not kill you makes you stronger,’” says Mark D. Seery of the University at Buffalo. His paper on adversity and resilience appears in the December issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science.
