“Although gender differences on average are not under dispute, the idea of consistently and inflexibly gender-typed individuals is,” Bobbi J. Carothers of Washington University in St. Louis and Harry T. Reis of the University of Rochester explained in their study. “That is, there are not two distinct genders, but instead there are linear gradations of variables associated with sex, such as masculinity or intimacy, all of which are continuous.”

Analyzing 122 different characteristics from 13,301 individuals in 13 studies, the researchers concluded that differences between men and women were best seen as dimensional rather than categorical. In other words, the differences between men and women should be viewed as a matter of degree rather than a sign of consistent differences between two distinct groups.

A Harvard professor has hatched a plan to bring back the Neanderthals—but he needs an “adventurous” female volunteer to deliver a knuckle-dragging bundle of joy.

The 2D:4D ratio is considered a crude measure to indicate exposure to androgens (testosterone) in the womb. Testosterone exposure in utero has been correlated with various physical and behavioral traits.

The 2D:4D ratio is present before birth, ruling out any environmental causes. It is calculated by measuring the length of the right index finger from the crease where it joins the hand. A similar measure is taken of the right ring finger. Divide the length of the index finger of the right hand by the length of the ring finger. A longer index finger will result in a ratio higher than 1, while a longer ring finger will result in a ratio of less than 1. Ratios lower than 1 are correlated with testosterone exposure in the womb.

Some studies suggest that digit ratio correlates with health, behavior, and even sexuality in later life. Wikipedia has a list of traits correlated with digit digit ratio, including links out to detailed information about each one.

Being Cruel: It’s Not Blind Obedience; There is Enthusiasm in the Act

We’ve relied on the Milgram Experiment (http://en.wikipedia.org/wiki/Milgram_experiment) and the Stanford Prison Experiment (http://en.wikipedia.org/wiki/Stanford_prison_experiment) for explaining how and why ordinary people, like ourselves, can commit acts of extreme cruelty and harm. While they tell part of the story, it seems we may have overlooked other important pieces of human motivation inherent to committing cruel acts. 

A new study argues that “…tyranny does not result from blind conformity to rules and roles. Rather, it is a creative act of followership, resulting from identifying with authorities who represent vicious acts as virtuous. “Decent people participate in horrific acts not because they become passive, mindless functionaries who do not know what they are doing, but rather because they come to believe—typically under the influence of those in authority—that what they are doing is right,” Professor Haslam explained.”

Conclusions

What can we do to encourage people to help more?

  1. Present them with a single, identifiable victim who they can help: people are more motivated to help if they can feel a personal connection with the victim.

  2. Appeal to their emotions: heightened emotional responses encourage altruistic behaviour.

  3. Instill a sense of responsibility to help, and an understanding that doing so is not futile.

Men with partners increase the space they feel comfortable with between themselves and an attractive woman if exposed to the bonding hormone oxytocin.

René Hurlemann at the University of Bonn in Germany and colleagues gave men either a sniff of oxytocin or a placebo before asking them to choose the ideal distance for an interaction with a woman. The distance that they felt was comfortable significantly increased after sniffing oxytocin, but only for men in relationships.

The team conclude that oxytocin discourages partnered but not single men from getting close to a female stranger.
