Sex and Statistics

In the Chimp world;

“In contrast to humans, the researchers found, male chimps find older females more desirable, approaching them more often to mate, fighting more with other males over them and mating with them far more frequently than with younger females. That is true even for higher-ranking male chimps, which have more choice of mates. The findings confirm the earlier results of other researchers.

"Multiple lines of evidence indicate that unlike humans, female chimpanzees become more sexually attractive with age," the researchers report in the Nov. 21 issue of the journal Current Biology. "This study demonstrates that male chimpanzees do not merely disdain young females, but actively prefer older mothers to younger mothers."

In the Human world;

Braving "robbing the cradle" jokes, almost one-third of women between ages 40 and 69 are dating younger men (defined as 10 or more years younger). According to a recent AARP poll, one-sixth of women in their 50s, in fact, prefer men in their 40s…

But what about the notion that men are "hard-wired" to seek a smooth-faced, curvy receptacle for reproduction and thus are drawn to younger women? "Humans are relatively flexible species," Michael R. Cunningham, Ph.D., a psychologist in the department of communications at the University of Louisville, tells WebMD. "Factors other than biological can be attractive. You can override a lot of biology in pursuit of other goals."

Interestingly, Cunningham did an unpublished study of 60 women in their 20s, 30s, and 40s, who were shown pictures of men aged to those decades. "The women," he says, "were more interested in men their own age or older."

As for the men, he says: "I guess it could be nice not to hang around a ditz with no knowledge of music or something like that."

In the blue-eyed world;

Blue-eyed men prefer blue-eyed women, apparently because eye color can help reveal whether their partner has been faithful, researchers said on Monday.

“Before you request a paternity test, spend a few minutes looking at your child’s eye color,” Bruno Laeng and colleagues at the University of Tromso in Norway said in the study.

Is there a universal positivity bias in attributions? A meta-analytic review of individual, developmental, and cultural differences in the self-serving attributional bias

Researchers have suggested the presence of a self-serving attributional bias, with people making more internal, stable, and global attributions for positive events than for negative events. This study examined the magnitude, ubiquity, and adaptiveness of this bias. The authors conducted a meta-analysis of 266 studies, yielding 503 independent effect sizes. The average d was 0.96, indicating a large bias. The bias was present in nearly all samples. There were significant age differences, with children and older adults displaying the largest biases. Asian samples displayed significantly smaller biases (d = 0.30) than U.S. (d = 1.05) or Western (d = 0.70) samples. Psychopathology was associated with a significantly attenuated bias (d = 0.48) compared with samples without psychopathology (d = 1.28) and community samples (d = 1.08). The bias was smallest for samples with depression (0.21), anxiety (0.46), and attention-deficit/hyperactivity disorder (0.55). Findings confirm that the self-serving attributional bias is pervasive in the general population but demonstrates significant variability across age, culture, and psychopathology.”
