Sapolsky’s Behave, Part 2 – Or, Understanding Your Political Opposites (If You’re Interested in That . . . )

This is the second of two posts reviewing Robert Sapolsky’s Behave – the first post is linked here.

Neuroscientist Robert Sapolsky’s Behave (Penguin, 2017) is a long but rewarding read. The first half of the book – 300 pages – delves into the particulars of brain regions and their development, cerebral enzymes, and genetics. Rewards come to the reader who continues to the last half of the book. Sapolsky is insightful, and his colloquial writing style humors, entertains, and instructs.

Sapolsky’s purpose is to explain human behavior – why, how, and what.

jalbm.behave.1As promised in my previous post, this post focuses on a juicy topic: the biology of political loyalties and tendencies. I love Sapolsky’s sub-heading (hardcover, p. 444) in Chapter 12 – “Hierarchy, Obedience, and Resistance” – that introduces the juicy section: “OH, WHY NOT TAKE THIS ONE ON? POLITICS AND POLITICAL ORIENTATIONS.”

Here We Go . . .

Sapolsky asks if there are “psychological, affective, cognitive, and visceral ways” in which left-leaners and right-leaners tend to differ. He answers by saying there are “fascinating findings” which he summarizes under the categories of intelligence, intellectual style, moral cognition, and psychological differences.

Even so, he posits an important disclaimer: rather than categories of stereotypes or essentialisms, what stands out in each group of partisans are internal consistencies which, he claims, are evident in both political and apolitical realms and have bits of biology undergirding them.

In the category of intelligence, he references a well-known study from the 1950s – one, however, not always verified by other similar studies – that suggested a link between lower intelligence and conservative ideology. (I told you this would be juicy.) Better supported, Sapolsky writes, is a link between lower intelligence and a specific sub-type of conservatism: right-wing authoritarianism. This link is a concern today just as much as it was in post-WW II Europe, when researchers and political scientists sifted through the wreckage caused by so many submitting to Hitler’s authoritarian ways. Right-wing authoritarianism, Sapolsky says, offers simple answers (to complex societal problems), ideal for people with poor abstract reasoning skills.

As for intellectual style, Sapolsky brings us to the dancefloor to help explain psychological studies that illustrate differences between conservatives and liberals. See the guy tripping over his feet while trying to dance? Partisans, asked to give a snap judgment of the lousy dancer, agree that the guy’s clumsy. But given more time to ponder the situation . . . liberals more readily entertain possible reasons for his lousy dancing (perhaps a physical ailment, or a father who disdained dancing) whereas conservatives tend to stick with their first instinct. Sapolsky says that “conservatives start gut and stay gut; liberals go from gut to head.”

Sapolsky hastens to say that right-leaners sticking with their gut doesn’t mean that they are incapable of going deep intellectually. Far from it: both liberals and conservatives are equally capable of presenting the other’s perspective, showing intellectual dexterity. Liberals, though, show greater comparative motivation toward entertaining situational explanations – the descriptor “bleeding heart” fits. Many conservatives, during the George W. Bush presidency, became comfortable with the term “compassionate conservatism” – in part, an attempt to address the criticism of cold-heartedness.

An interesting aside: Donald Trump, before becoming president, spoke often of going with his “gut feel.” He’s continued to speak in similar fashion as president. By this marker, Trump is a card-carrying conservative.

Differences between partisans in the category of moral cognition are revealed by their typical response to this question: Is it permissible to disobey a law? Conservatives, with their affinity for law and order, answer “No” because disobedience undermines cherished authority. Liberals, on the other hand, answer “Yes, if it’s a bad law” – authority subsumed to their affinity for fairness for all. Another question: Should NFL players be allowed to kneel during the national anthem? Conservatives, with their affinity for sacredness – “Never.” Liberals will allow for it, if they can be convinced that the reasons and circumstances undergirding the action merit it.

As for the category of psychological affect, Sapolsky says that liberals tend to be more comfortable with ambiguity than are conservatives, who tend to be more comfortable with structure and hierarchy. Are our best days ahead of or behind us? Generally more comfortable with novelty, liberals anticipate, with needed reforms, a brighter future ahead. Conservatives, generally more comfortable with that which is familiar, speak of the good old days that should be returned to – “Make America Great Again.”

What is the role of government? Liberals: to provide social services and education for its people. Conservatives: to protect its people, with a strong military leading the way. Apropos, Sapolsky sites a study that reports Republicans having three times more dreams involving loss of personal power than do Democrats. Conservatives, especially those with authoritarian sympathies, are more prone to “threat perception” – fears and anxieties about potential dangers – than are their political counterparts. Of the two, which group reports being happier? Despite their hopes for a better future, liberals, who are more discomfited by inequality, report increasing unhappiness as inequality rises. Conservatives, for their part, self-report no decline in happiness in the midst of increasing inequality.

This is All Quite Interesting . . . But, Is There Any Biology Behind These Differences?? 

In the first part of the book, Sapolsky details the workings of the insula cortex, a subpart of the amygdala. An important player in the brain’s “fight or flight” response mechanism, the insula detects threats and alerts the rest of the body. As an example, the insula (in most of us) activates when we see a cockroach. It also activates when someone from a rival tribe – a “Them,” not an “Us” – is detected in our field of vision or thought.

“Social conservatives,” Sapolsky writes, “tend toward lower thresholds for disgust than liberals.” Images depicting gay marriage and abortion, for example, activate the insulas of conservatives. But show images depicting petulant plutocrats and arrant aristocrats to liberals, and their insula-triggered disgust factor goes off the chart. “Political orientation about social issues,” Sapolsky comments, “reflects sensitivity to visceral disgust and strategies for coping with such disgust.” Biologically, liberals and conservatives (more so) rely upon disgust as a metric for determining moral behavior. Disgust, however, as Sapolsky warns, shifts generationally.

Sapolsky finishes up this section on political orientations and biology with a pithy summary: “If it makes you puke, you must rebuke.”

So, Where Does This Leave Us?

Sapolsky gives hyper-partisans reasons to step back, take a deep breath, and re-learn one of the main lessons that evolution teaches: diversity makes us stronger and helps us survive. Behavioral differences – including those displayed in political preferences – harken back at least to some biological wiring.

Nobody wants to have to sit at the Thanksgiving table while the prototypical crazy uncle goes on a political rant. Have Sapolsky’s Behave at the ready and ask that he give it a look-over before he comes back to the next family dinner.

Sapolsky’s Behave, Part 1

This is the first of two posts reviewing Robert Sapolsky’s Behave – the second post is linked here.

Why Zebras Don’t Get Ulcers is one of my all-time favorite book titles – to boot, the book rocks. Robert Sapolsky, the esteemed American neuroscientist, writes that acute stress is a life-saver: a zebra sees a lion and runs like the wind. We humans are equipped with the same fight-or-flight response mechanism, and though we can’t run like zebras, we benefit similarly. Zebras and other animals have less brain capacity than we do, consequently they’re no good at worrying. We are capable of prolonged worrying which elevates our stress levels to chronic status, which in turn gives us ulcers, hypertension, and other life-threatening maladies. Whereas acute or momentary stress can be a life-saver, chronic stress is a slow killer.

The long-time Stanford professor originally published his book in 1994. It soon became a classic and I read its third edition in the summer of 2006, recommended from the book list of a leadership class I was taking. In the years that have since passed, I’ve referenced the book multiple times. I opine that there’s a connection between the increasing rates of pet ownership and social anxiety in the US. Most dog breeds are good with acute stress – it’s their job to bark when a stranger comes to the door – but, like zebras, they’re no good at achieving chronic stress levels. What a remedy for us to come home after a long day to a tail-wagger who’s happy to see us and whose beating heart warms and calms our own.


In 2017,  Sapolsky published Behave: The Biology of Humans at our Best and Worst. This big book of 675 pages (not including notes) touches on some of the same territory as Zebras, but Sapolsky enlarges his scope to include discussions on inequality and egalitarianism, the effects of poverty on health, the dichotomies of “Us versus Them,” the development of empathy and compassion within the determining powers of genetic code and environment, and – it doesn’t get much better than this – the biology of political orientations and loyalties.

Let’s take a look at each of these themes. The “last best” theme will be covered in the second post in this review.

Stratified, or non-egalitarian, societies are better suited at conquering and survival when times get tough. This helps explain their ubiquity in the history of civilization. Because of their stratification, mortality is sequestered to the lower classes. Essentially, the unequal distribution of wealth and access to resources translates to the unequal distribution of death.

Modern democracies – and the advances associated with industrialization – have balanced things out (somewhat) concerning life expectancy rates between the higher and lower classes, but rampant inequalities still threaten various markers of 21st century life in many societies: weakening social capital, exacerbating poor health, increasing crime and violence. Sapolsky points out, most tellingly, that “inequality means more secession of the wealthy from contributing to the pubic good.” Inequality, without the mitigating effects of egalitarianism, is self-perpetuating.

Which brings us to the dichotomization of Us versus Them. Evolution has equipped us with the life-saving ability to differentiate between friend and foe, and we all derive much happiness and joy from being part of “Us” groups – whether golf buddies, sorority sisters, or mates in a military service platoon.

But when not held in proper check, this same ability can produce, as Sapolsky says, “oceans of pain” – with white supremacy groups at the top of the “For example” list.

Sapolsky advises his readers to distrust essentialism – the idea, like stereotyping, that people groups are always defined by a fixed set of characteristics and traits. He warns that what we think to be rationality is often just rationalization. Because of our “automatic tendency to favor in-groups over out-groups,” our seemingly rational explanations about the behaviors of others are sometimes better described as evidences of tribalism.

The recent rise of authoritarianism – Trump, Duterte in the Philippines, Bolsonaro in Brazil, Morales in Guatemala, along with the long arc of rule by Trump’s buddy Putin in Russia – is a troubling trend for many of us. Sapolsky shows that this rise benefits from the deep roots that conformity and obedience have in the human family. It fits hand in glove with another tendency or conditioned response in humans: our natural like of hierarchies. Sapolsky: “Hierarchies establish a status quo by ritualizing inequalities.” (Hierarchies, from ant colonies to corporate employee structures, are capable of unparalleled performance and production. My purpose here, as is Sapolsky’s in Behave, is to focus on inequality.)

Unlike the chimpanzees and baboons that Sapolsky has studied for much of his life, we humans in democratic societies actually choose our (political) leaders. He sites studies showing that we elect leaders with more masculine traits – high forehead, prominent jaw lines – during times of war and younger, more feminine faces during times of peace. Another study he sites had children looking at pictured pairs of faces where they were asked to choose their preference between the two for a hypothetical boat trip. The paired photos were actually competing candidates from obscure political races, and the children were asked which one would be most competent as captain for the boat trip. Their skippers, 71 percent of the time, were the actual winners of the elections.

We have entrenched biases and preferences. We have the option today (exercised by many) to consume the media output most aligned with our positions . . . and, like we often see partisans do on TV, we end up yelling at and past each other. Rationality or rationalizing? Sapolsky, again, says the latter: “Our conscious cognitions play catch-up to make our decisions seem careful and wise.”

If we’re only watching Rachel Maddow or only Sean Hannity – we’re not doing much more than stoking our own fire. Rational deliberation comes not from “doubling down” but from consideration of different points of view.

As promised, we’ll go deeper with Sapolsky into the biology of our political loyalties and preferences in the next post. Stay tuned!

The Joy of Reading (Good Stuff)

During a recent radio interview, I heard someone bemoan all the reading of insignificant detritus he’s done on the Internet, while the good books on his To Read list gather dust: “It’s like I’m on the millionth page of the worst book ever – but I can’t stop reading it.” We’ve all wasted precious time; it’s not the worst sin in the world. But when you find yourself surfing the net and reading about what O.J. Simpson had for breakfast in his prison cell, or about a sighting of Kim Kardashian breast-feeding her baby in public – then you know that some better part of the world is passing you by.

When you start to tally up all the time that gets away, the math is instructive. If you took twenty minutes each day to read good stuff (see below), you’d end up with 120 hours per year. Depending on reading speed and book size, that’s between six to twenty-five books a year. That’s time well spent – directly beneficial to you and indirectly beneficial to those whose paths you cross.

Reading a book is akin to having a conversation with another human being: a deep, meaningful, thought-out exchange that as readers we are able to conduct on our own time. Perhaps a bit grandiose to say, but having a varied and wide reading list is akin to having a conversation with the world. This conversation makes us more aware of our place in the world, and (hopefully) better citizens of it.

The home bookshelves – a blessed mess, yes.

Good Stuff: While I do read fiction, I’m admittedly over-balanced on the non-fiction side. Taylor Branch’s Parting the Waters, Dee Brown’s Bury My Heart at Wounded Knee, Paul Johnson’s Modern Times, Richard Rhodes’s The Making of the Atomic Bomb, and Daniel Yergin’s The Prize are but a few of the captivating books I delved into over the years. There are many other books I would add to my A-list: Edmund Morris’s Dutch, Bill Bryson’s A Short History of Nearly Everything, and Jared Diamond’s Guns, Germs, and Steel are but a few others.

While my three kids were in college, they received from their old man a hand-picked bundle of books from the good stuff list. Lucky them! I realized they weren’t going to read these books while in college – they had other books to read and happenings to attend. Yet, like a seed planted in good soil, I trust that this gesture someday will bear beneficial fruit.

Occasionally, Facebook friends will call out for “Top 10” or “Best Ever” reading lists. As we all know, there’s a lot of good stuff out there. It’s eye-opening to see what others are reading; it enlarges the conversation. It’s a blessing to have time to read.

There’s a great difference between information and knowledge. The Internet provides plenty of the former, whereas good books help engender the latter.

I’ll continue to blog on the net, with the purpose of supporting common good development, pointing out the good books along the way that help us get there.

Read on, my friends.
