Book Review:  "A Hunter-Gatherer's Guide to the 21rst Century. Evolution and the Challenges of Modern Life." by Heather Heying and Bret Weinstein. 2021

This provocative book is written by wife and husband evolutionary biologists, Heather Heying and Bret Weinstein. These scientists are unusual. They have the guts to act on their liberal, progressive convictions --- they resigned from their tenured, 15 year long faculty positions at Evergreen College, standing up to the scourge of political correctness.

They tackle big questions about our species with clarity, wit, and the wide perspective of the evolutionary lens.

They see humans in the modern world as hyper-novel. They say: “ … humans are extraordinary well adapted to, and equipped for, change. But the rate of change itself is so rapid now that our brains, bodies, and social systems are perpetually out or sync. For millions of years, we lived among friends and extended families, but today many people don’t even know their neighbors’ names. Some of the most fundamental truths – like the fact of two sexes are increasingly dismissed as lies. The cognitive dissonance spawned by trying to live in a society that is changing faster than we can accommodate is turning us into people who cannot fend for ourselves. Simply put, it’s killing us.”

The authors claim, “if we don’t figure out how to grapple with the problem of accelerating novelty, humanity will perish, a victim of its success.”

They understand the need for a revolution to save the human species --- and they comprehend the ancient wisdom to let what works for humans, remain. They rightly observe that most revolutions make things worse ---- we need to respect traditions – such as religious belief and respect for ancient wisdom that informs us what works in our society. They quote the writer G. K. Chesterton who reminds us to be careful when we approach a fence --- we shouldn’t tear down the fence just because we don’t know why the fence is there.

Heying and Weinstein are wedded to first principles – assumptions that cannot be deduced from any other assumptions. They are aware of the naturalistic fallacy of what is or what is natural must be good --- a confusion of fact and value. What is, is not always what should be.

Heying and Weinstein propose practical guidelines for such important topics, and chapter titles as, “Ancient Bodies, Modern World;” “Medicine;” “Sex and Gender,” “Parenting;” “Becoming Adults;” “Culture and Consciousness,” Heying and Weinstein tell us much about their views of human nature informed by evolution.

The following are examples of the “Corrective Lens” offered at the end of each chapter:

• Become skeptical of novel solutions to ancient problems.
• Become someone who recognizes patterns about yourself.
• Move your body every day.
• Do not forget that food is social lubrication for humans.
• Develop a ritual in advance of sleep.
• Avoid sex without commitment.
• Do not succumb to social pressure to embrace easy sex.
• Do not helicopter or snowplow your children.
• Be the kind of person you want your children to be.
• Civilization needs citizens capable of openness and inquiry.
• Always be learning.
• Get over your bigotry.
• Learn how to give useful critique without backing the other person into a corner.
• Be barefoot as often as possible.
• Sit around more campfires.

For millennia, humans have been sitting around campfires, sharing ideas, bonding with each other and solving problems.

I welcome the opportunity to sit around a campfire with Drs. Weinstein and Heying, college students, and a group of ideological diverse academics from a variety of disciplines to ask questions, discuss disagreements, and digest more intellectual, gourmet food found in this excellent book.

Because I’m a psychologist with 45 years of experience, I would challenge the authors allergy to psychiatric medications. I’ve witnessed many children, adolescents and adults benefit from these medications, sometimes preventing suicide, major depression, academic and job failures. It’s difficult to get people to take 8 days of antibiotics; and more difficult to get people to take daily psychiatric drugs unless these medicines help. Psychiatric medications treat our “hard drive” and talking therapy treats our “software.” Both talking therapy and pharmacotherapy are often essential for treating mental distress. Humans have the most flexible software of any animal on the planet. A core deficit in our understanding of the mind is we have no clue how our material brain creates our sense of “I” - our sense of self.

I would like to know how these authors would square their pessimistic view of our world with the writings of psychologist Steven Pinker - “Enlightenment Now,” and the physician, the late Hans Rosling, co-author of, “Factfulness.” Both authors describe the tremendous progress we’ve made in the last 200 years such as reducing world poverty from 90% to 10%; increasing life span; reducing infectious diseases; and much more. Perhaps Pinker and Rosling would say even these brilliant evolutionary biologists are shaped by millions of years of evolution to adopt a negativity bias, keenly aware of threats to our species.

Don’t miss their Dark Horse podcasts.

To help keep my sanity in this world, I turn to another quote of G. K. Chesterton: “He is a sane man who can have tragedy in his heart and comedy in his head.”
