Science finds that being kind really does pay off
It makes us feel better and healthier and ‘seems universal’
Acts of kindness may not be that random after all. Science says being kind pays off.
Research shows that acts of kindness make us feel better and healthier. Kindness is also key to how we evolved and survived as a species, scientists say. We are hard-wired to be kind.
Kindness “is as bred in our bones as our anger or our lust or our grief or as our desire for revenge,” said University of California San Diego psychologist Michael McCullough, author of the forthcoming book “Kindness of Strangers.” It’s also, he said, “the main feature we take for granted.”
Scientific research is booming into human kindness, and what scientists have found so far speaks well of us.
“Kindness is much older than religion. It does seem to be universal,” said University of Oxford anthropologist Oliver Curry, research director at Kindlab. “The basic reason why people are kind is that we are social animals.”
We prize kindness over any other value.
When psychologists lumped values into 10 categories and asked people what was more important, benevolence or kindness, comes out on top, beating hedonism, having an exciting life, creativity, ambition, tradition, security, obedience, seeking social justice and seeking power, said University of London psychologist Anat Bardi, who studies value systems.
“We’re kind because under the right circumstances we all benefit from kindness,” Oxford’s Curry said.
When it comes to a species’ survival, “kindness pays, friendliness pays,” said Duke University evolutionary anthropologist Brian Hare, author of the new book “Survival of the Friendliest.”
Kindness and cooperation work for many species, whether it’s bacteria, flowers or our fellow primate bonobos. The more friends you have, the more individuals you help, the more successful you are, Hare said.
For example, Hare, who studies bonobos and other primates, compares aggressive chimpanzees, which attack outsiders, to bonobos where the animals don’t kill but help out strangers. Male bonobos are far more successful at mating than their male chimp counterparts, Hare said.
McCullough sees bonobos as more the exceptions. Most animals aren’t kind or helpful to strangers, just close relatives, so in that way it is one of the traits that separate us from other species, he said.
And that, he said, is because of the human ability to reason.
Humans realize that there’s not much difference between our close relatives and strangers and that someday strangers can help us if we are kind to them, McCullough said.
Reasoning “is the secret ingredient, which is why we donate blood when there are disasters” and why most industrialized nations spend at least 20% of their money on social programs, such as housing and education, McCullough said.
Duke’s Hare also points to mama bears to understand the evolution and biology of kindness and its aggressive nasty flip side.
He said studies point to certain areas of the brain, the medial prefrontal cortex, temporal parietal junction and other spots as either activated or dampened by emotional activity.
The same places give us the ability to nurture and love, but also dehumanize and exclude, he said.
