Study: Hairless, Middle-Aged Apes Still Middle-Aged Apes

Why is happiness U-shaped? In countries around the world, people tend to get less happy up through about age 50 or so, and then rebound and get happier as they age. The Los Angeles Times provides us with the usual explanation:

By midlife, youth’s hot-blooded drive to mastery has driven off. Responsibilities abound. Decades of striving — to raise a family, to establish oneself in the community, to climb the professional ziggurat — have shown us the mountaintop and, with it, the limits of our reach and usefulness. A recognition of our mortality settles in. In the years after midlife, the theory goes, humans shoulder fewer burdens for the care of others. Their time horizons are shorter, prompting them to focus on people and activities that give pleasure and meaning to their lives. They regret less.

That’s a very convincing narrative, and we humans love narratives, don’t we? But guess what? It turns out that great apes, who feel none of these things, also experience U-shaped happiness:

When the composite well-being score for each ape was plotted according to his or her age, the result was the same distinctive U-shaped curve seen universally in humans. Around the ages of 28 and 35 — roughly the midpoint of the chimpanzees’ and orangutans’ expected life spans — moods sagged, animals became less socially engaged and they were less likely to persist in attaining the things they desired.

….For social scientists who saw shifts in happiness in strictly human terms, the findings were a forceful reminder that people have not evolved as far as we may think beyond the great apes, said Stacey Wood, a neuropsychologist at Scripps College in Claremont who wasn’t involved in the study.

….”It pushes more toward the possibility that this is biological,” added Arthur Stone, a professor of psychiatry at Stony Brook University in New York who was not involved with the study. Whether it’s hormones, brain structure, neurochemicals or some other factor that causes the middle-aged psyche to power down will require further research, Stone said. But from now on, he said, social explanations alone will not suffice.

So free will takes another hit. But then, I would say that, wouldn’t I?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
