The one-size-fits-all model of relationship recognition – exemplified by marriage – is no longer appropriate.
Research shows that hunter-gatherer storytellers were essential in promoting co-operative and egalitarian values before comparable mechanisms evolved in larger agricultural societies, such as moralising high-gods. Storytellers were also more popular than even the best foragers, had greater reproductive success, and were more likely to be co-operated with by other members of the camp.
The anti-natalist philosopher David Benatar argues that it would be better if no one had children ever again.
People tend to trust strangers of the opposite gender more than those of the same gender in mixed-gender situations. Furthermore, females trust females much more than males trust males.
Social networks powerfully shape memory, and people need little prompting to conform to a majority recollection
People in masses behave akin to particles in a fluid or gas. In physics, it is not necessary to know the properties of every individual particle to calculate with a high probability the direction of flow of a large number of gas molecules. It is enough to understand their mean motion properties. We can take the same approach when looking at flows of human masses.
If we can stop violence in one person, that spreads to their social network. We're actually preventing violence not only in that person, but potentially for all the people they come in contact with.
Having an uncertain position in the rhesus social hierarchy may be harmful to the health of those at the top of the hierarchy but not necessarily for those at the bottom. The monkey model could one day help doctors learn more about the way that social hierarchy affects the health of humans.
From London to Lagos, cities across the world are reacting to the rise in begging with a variety of often controversial measures.
Indian women are supposed to be treated as daughters in their husbands’ homes, but in reality many are forced into a life of near slavery.
Greed and fear are the basic reasons underlying problems with teamwork. People are afraid that their contribution will mainly benefit those people who themselves contribute nothing. That's why people hold back and invest in self-protection rather than cooperation.
After being on the losing side of a fight, men seek out other allies with a look of rugged dominance about them to ensure a backup in case of future fights. Women in similar situations however, prefer to seek solace from allies whose faces suggest they can provide emotional support. There is an evolutionary root to the differences in how men and women seek out allies and it is driven by the need for social survival in the long run.
Our sense of what we know about something is increased when we learn that others around us understand it.
The associations or attachments that we have with an object leak into our movements in unintended ways when we interact with them.
Most voters are ignorant or misinformed because the costs to them of acquiring political information greatly exceed the potential benefits. They can afford to indulge silly, false, delusional beliefs — precisely because such beliefs cost them nothing. After all, the chances that any individual vote will decide the election is vanishingly small. As a result, individual voters tend to vote expressively, to show their commitment to their worldview and team. Voting is more like doing the wave at a sports game than it is like choosing policy.
Soviet hippies turned against a state that surrounded them with enforced conformity.
The current reality of micro-mobilization -- swiftly organized efforts often propelled by ubiquitous social networking and digital technologies, like camera-enabled smartphones -- helps people to more readily sympathize with certain social movements and protest acts.
The total size of population that can be supported depends on the proportion of cooperators: more cooperation means more food for all and a larger population. If, due to chance, there is a random increase in the number of cheats then there is not enough food to go around and total population size will decrease. Conversely, a random decrease in the number of cheats will allow the population to grow to a larger size, disproportionally benefitting the cooperators. In this way, the cooperators are favoured by chance, and are more likely to win in the long term.
Contemporary husbands face higher risk of divorce when they do not fulfill the stereotypical breadwinner role, by being employed full-time.
High-ranking people don't always turn out to be selfish jerks. It all depends on whether they feel worthy of their prominent social position.
