Sukupuolten välisiä eroja

Steven Rhoads on kirjoittanut kirjan sukupuolten välisistä eroista. Täältä löytyy joitain ydinkohtia:

- "About 6 out of 7 men report masturbating more often than the average woman."

- "Among married men, 7 percent have had sex with more than twenty partners. Among male homosexual couples, 43 percent have had sex with more than twenty partners. Among lesbian couples, only 1 percent have had sex with more than twenty partners."

- "Women on average bench-press about one-third of what men do."

- "Women prefer average-looking or even unattractive doctors to very attractive teachers."

- "Highly-paid professional women have an even stronger preference for high-earning men than do women working in less well-paid jobs."

- "Men prefer a woman shorter than they are, and women a man who is taller. But on average men prefer her to be 4.5 inches shorter, while women want him a full 6 inches taller."

Steven Rhoads kertoo sukupuolten välisistä eroista vanhemmuudessa.

- Fathers tend to think that mothers worry too much about the children. Guilt mothers always think they could be and thus should be doing more with their kids. And moms, since they are worriers and parent with more intensity, are taskmasters with husbands about what needs doing and how it should be done. They tend to make dad into an assistant mom.

- Fathers frequently feel neglected by their wives who they think put their relationship with the kids ahead of their relationship with their husbands.

- Dads frequently think moms are too soft, for example, in comforting an older child who cries excessively when he falls down.But dads think this a larger problem as the kids get older and especially with teenage boys.
It's hard for a mom, used to being a nurturer, to become a disciplinarian, especially with a surly teenager who is now taller and looms over them. Mothers, loaded with estrogen and oxytocin, tend to be peacemakers. When dads try to discipline sons, the mother can be tempted to try to be a mediator rather than support the father. This can infuriate her husband.

Marginal revolutionista löytyy linkki artikkeliin, jossa kerrotaan, miksi shakin suurmestarit pärjäävät muita paremmin. Sama metodi toimii tieteessäkin:

...Novices were more likely to convince themselves that bad moves would work out in their favour, because they focused more on the countermoves that would benefit their strategy while ignoring those that led to the downfall of their cherished hypotheses...Conversely, masters tended to correctly predict when the eventual outcome of a move would weaken their position. "Grand masters think about what their opponents will do much more," says Byrne. "They tend to falsify their own hypotheses."

The philosopher Karl Popper called this process of hypothesis testing 'falsification', and thought that it was the best way to describe how science constantly questions and refines itself. It is often held up as the principle that separates scientific and non-scientific thinking. But cognitive research has shown that, in reality, many people find falsification difficult. Until the latest study, scientists were the only group of experts that had been shown to use falsification.

Naiset preferoivat renttuja lyhyissä seksisuhteissa, mutta eivät halua tyttärensä kihlautuvan rentun kanssa. Mikä todistaa sen hypoteesin puolesta, että naiset haluavat mahdolliselle pojalleen rentun geenit.
