Definitely the safest place to practice my chainsaw juggling.

Simply put, your brain is not well designed for finding the truth. And, until you accept this and why it is so, you will fail to understand why good-natured, intelligent people can’t seem to agree on the belief systems like religion and politics. But, at the cost of accuracy, we may actually be getting something much more powerful. This post talks about the real origin and main brain function of human reasoning, and why our social inability to settle on certain ‘facts’ is a persistent feature of being human. Hopefully, those predictably infuriating dinner table debates will make much more sense.

The Engine of your Thoughts

Our capacity for thinking is awesome. In fact, it’s so awesome that we can sit here and actually ponder how awesome it is. A pillar of your cognition is your ability to reason through stuff to come to a conclusion about it. It’s both the awareness of that conclusion as well as a rationale that justifies why it is so. How sophisticated!

What you and most of us believe about the purpose of our reasoning powers is that it improves our knowledge about the world (accuracy) and make better decisions (enlightened actions). It’s not. Most of us are wrong; and, mountains of research in psychology and neuroscience suggest that this is false.

The main function of Reason is not to enhance individual cognition through delivering accuracy. In fact, it is often designed to distort accuracy for other purposes.

That’s absurd, right?

So Many Problems: A Broken Brain?

In case you’re not intimately aware, basically all humans have significant systematic biases in the way they search for and interpret certain information. Those biases are always there, running on autopilot, skewing the information we get from our environment. Those crafty little biases chronically lead to epistemic distortions, and oftentimes, pretty crummy decisions.

Here’s a few major cognitive biases you harbor:

  • Confirmation bias. You are much more likely to accept information that reinforces your belief about something, and much more likely to reject information that calls that belief into question.
  • Motivated reasoning. Not only your reception of evidence, but also your search for evidence about some conclusion is guided by your interest to support your position and oppose the contrary one.
  • Belief entrenchment. By merely thinking about an issue, your current attitude will become more entrenched. You don’t consider so much as you defend. The more you reason the more entrenched you get. Does this sound anything like the last facebook debate you were in? Even when you and your counterpoint are exposed to the same new info, your attitudes will likely actually polarize further! Simply watch this play out with the US gun control debate after our next mass shooting, and then punch yourself in the neck in frustration.

There’s a bunch more. Here’s a pretty big list. Face it. The way your brain handles info seems built to screw up in certain ways.

Weird. Your search for info is biased. Your propensity to change positions is biased. Your ability to handle abstract logical tasks suck. You stink at reasoning about relative probabilities too. It’s not just you; it’s all of us.

Oh, you’re educated, you say? Intelligent? Good for you, Professor Ego: Evidence shows that you are at least as much if not more affected by these biases. In fact, you’re better at making justifications than the rest of us, independent of accuracy. And, if you have more knowledge on a subject, your reliance on your biases are even easier to observe.

It looks like we are built to easily and readily make justifications for emotionally satisfying judgments and actions. While most people seem to consciously desire an accurate view of the world, our brains construct a coherent worldview at the expense of accuracy.

WTF? Is this all a big design blunder?

The Real Function of Reasoning

We’re not broken. Well, okay, maybe you are, but that’s beside the point. For the rest of us, our brains are operating on something even more important than finding an accurate view of reality. We are busy being great at arguing.

The function of reasoning is not epistemic. It’s to be persuasive, and to be resistant to the persuasion of others. There’s a compelling theory now championed by anthropologists Mercier and Sperber that argues that “Reasoning” is a suite of inferential processes oriented to convince others and to adopt compelling beliefs in order to flourish in collaborative communities. Yes, learning accurate facts happen, but more as a side effect of gathering the best information to help us argue better. To persuade, convince.

A Tad More In-Depth

Our juicy little minds consist of elaborate computational mechanisms honed under natural selection to improve relative fitness. Given that selection operates just as much on our social environment as our natural one, a set of social cognitive mechanisms have evolved and persisted to contribute to our relative fitness in that (extremely complex) environment as well.

When you can establish a bigger and more loyal coalition of friends and allies than others, you can manipulate the social environment in a way more conducive to your vision. If you’re really good at it, that environment becomes more calibrated to your wants and expectations, and you will reap much more from it than your in-group rivals can. And, the more intuitive and automatic arguing is for you, the less you’d have to toil over how to apply it.

My deeper point is this: Strategic social manipulation is actually a more important selection factor than even having an accurate view of the world. In our highly consequential social environment, your relative ability to convince others in your cohort is, in a sense, engineering reality itself. You are manipulating the very orientation and assumptions of the social system itself.

In essence, your deft powers of reason don’t actually adjust your beliefs to better reflect reality, they adjust social reality to better reflect your beliefs. If you’re the best at making arguments and evaluating the flaws of others, you become the main designer in what it means to be accurate. Powerful indeed.

You and the Group Both Benefit

Argumentation serves the group too. While the deft, charismatic individual could typically reap the most individual benefits, it empowers and orients the group, relative to rival groups. Reasoning as persuasion among a group enables coalitions of individuals to communicate and settle into one collaborative agenda. It makes human communication more deliberate, effective and advantageous. It shouldn’t be too surprising then that in general, women are found to be most attracted to males who demonstrate social dominance; in the long span of human prehistory, it has long entailed higher prospects of success than muscles, beauty, general intelligence, or even wealth.

The “Defects” Make Sense

When Reason is seen in this light, suddenly all those pesky cognitive biases make sense. It also explains why human logical performance is crummy until it is applied in a social context involving dialogue. It all seems to purposely fit together. And, it makes sense that always be maximally convincing and maximally accurate; sometimes the most accurate information may undermine our case being made to others. When caught between being accurate and being ‘right’, being right is generally much more consequential.

Human reasoning is not some deeply flawed mechanism; it is a remarkably efficient specialized system adapted to convince others of the social facts that work best for us.  It is not designed to guide us to the best choices but the ones that are easier to justify to others. As an evolved arguer, you exquisitely look for arguments that support of convenient conclusion, and favor conclusions for which some argument can be found.

So What?

Debate around the dinner table. Debate on facebook. Persuasion in the office. Or at home. It can be terribly frustrating until you acknowledge the experience for what it is.

We may not have brains designed for being epistemically accurate. But, we are designed for something even more important: gaining control over engineering our social environment better than others. As for the whole accuracy thing, it turns out that being accurate in assessments, in general, will lead to better outcomes, so occasionally accurate facts will rise to the top. And, we have developed scientific methods and instruments to help us overcome our intuition to persuade and build real knowledge.

So just remember. When you are in debates, see it for what it is not: an experience to find the truth. See it for what it is: an battle for relative control over the attitudes and beliefs of your people. May the best brains win.

What is Culture and Who Cares if I Defy It?

Here in America, there is habitual talk of a culture war. Scholars write about it and our ideologues are on the front line declaring it, determined to prevail. Whether it’s the supposed war on Christmas, the war on family values, or the icons of religion in public institutions, the outcome of this war seems to matter deeply, maybe existentially, for many.

When most of us talk about culture, we are usually referring to two differing political visions among Americans about what to venerate and what to fear, loosely encapsulated in Traditionalism versus Progressivism. Although, some think even it’s just a thin veneer for a more fundamental class war.

I don’t think most of us have much of a clue about the nature of culture, and why good people are so divided by religion, politics, and authority.

Most folks just seem to follow their gut-thawts, presume its rightness and begrudge those who stand in their way. But grasping the nature of culture is crucial. We are subject to the conventions and social moral codes it implies, and whether we decide to embrace those codes or rebel against them.

I want to start at the root and build up. So, what is culture? Why does it exist? Why are some people so attached to some version of it, and others aren’t? How does it change and evolve? How should you and I face it?

This is part one of a four-part post on Culture. Here, I will try to get to the root of culture by defining what I think culture is, where it came from, and why it persists. In part two, I will talk about why some people are so explicitly attached to culture, why some aren’t, and why it looks the way it does here in the US. In part three, I will explain what I think are the levers that makes culture change and evolve. In part four, I will propose why I think it really matters for you specifically and why you can and should be more than a subject of it – you should also be an author of it.

What is Culture?

Lots of definitions of culture out there. Here’s an overview, but don’t waste your time. Most seem to describe the values, rituals, heroes, and symbols, of a group of people – in other words invocations of culture. But that isn’t really what it is.

Clifford Geertz was one of the most famous anthropologists on culture. He defined it as,

a system of inherited conceptions expressed in symbolic forms by means of which men communicate, perpetuate, and develop their knowledge about, and attitudes toward, life.

Meh. True. Descriptions like these are fine, but they make it possible to include nearly everything communicable as culture. It gets hard to ask, “what isn’t culture?”

These description also don’t shed light on the engine of culture. I guess what I want to know is what explains the stuff we call culture?

The Biological Basis of Culture

The question gets easier when we stop thinking about culture as a set of things and norms, and instead as an adaptive system – a process that yields a set of things and norms.

I think that culture is a biologically-rooted adaptation to optimize social life. I think culture was absolutely necessary for the pace and sophistication of human evolution. It’s prevalence is the story of human flourishing. Pay heed, and ignore the centrality of culture at your own peril.

Humans, like most life, evolved in fierce environments of scarcity and uncertainty. Thanks to a bunch of preadaptations, humans were disposed to a lifestyle where communal living conferred staggering advantages that solitary life could not. The extent of cooperation and cohesion of the group implied how well it could manipulate the environment. If you can increase control of the environment with cooperative strategies like, say, hunting and predictable distribution, you can decrease the precariousness of life. And, the better that your group could cooperate over other groups, the more likely your group’s descendents would define what it means to be human, both genetically and culturally. Thus, we as descendents of the most cohesive ancestral groups are hardwired to cooperate very well with kin and friends, and compete very well with rivals and enemies.

Cognitively, humans have evolved a programmed aversion to increasing uncertainty, and are generally risk averse to costly consequences. The more that communal living can endow predictability and success to life to its members, the more value its members would perceive it. Managing this social order is the basis of culture.

Specifically, communal groups faced three persistent problems of scarcity:

  1. Material economy: The distribution of limited resources, like food, or now, wealth.
  2. Reproductive economy: The distribution of access to sex.
  3. Mortality economy: The management of the death of members in the group.

Culture then, is a set of solutions that a locality of humans have developed to dealing with the persistent challenges of communal life. While practices, attitudes, and rituals may vary dramatically across space and time, all human groups have some set of them and they all serve to resolve these basic quandaries.

Threats to the Tribe

A community of people faces two types of threats:

  1. Internal threats. Within the group lurk free-riders – those pesky people that reap collective benefits without contributing their share. Their existence risks subverting the efficiency and predictability of the social order. There are three types of free riders: bullies, cheaters, and thieves. In different ways, these different free-riders impose both direct costs, and indirect costs of calling into question the possibility of future cohesion itself. Of course, if group cooperation is collapsing, no one wants to be the sucker left with nothing. The fear itself risks cascading defections from other members, known as the collective action problem. Bummer. I’m scared already!
  2. External threats. Outside of the group lurk rival groups that also want to thrive, and you’re probably in their way. They often see (rightly) that your group covets precious resources and is a latent threat in the future in case you want to someday take their land, food, and women.

The function of social order is to manage these threats. Thus, from flags to founding fathers, pioneer ethics to the 4th of July, the actual rituals, heroes, and symbols of a particular culture emanate from the community’s heritage facing these threats. And, if the social order cannot withstand these threats, insurrection will come from within to change it.

Why Culture is Still Super Important

Except perhaps in small groups, there is no single, immutable culture. As local cultures intersect in cosmopolitan spaces, the conventions and mores can bombard the others. The result is tension about the very thing that culture evolved to solve: uncertainty about how to manage scarcity and threats when they come.

The question of cultural preponderance is really important and it should not surprise us that ideologically-minded fight tenaciously for it. Whichever culture is preponderant defines the conditions under which a member should be punished by others. It defines the free-riders. It defines the enemies. And, if our own cultural mores are not preponderant, we can feel disenfranchised from the social order. Depending on other factors discussed next time, this can lead to either disengagement (consider civic life in forgotten urban ghettos), or conflict.

There’s a fascinating inference from all this. The future evolution of humankind is and hasn’t been merely biological selection. Natural selection works by privileging subsets of populations that better fit an environment than others. It happens anywhere there is competition among variations of people. My point is that humans operate in two environments – biological and cultural, meaning that correspondence to relatively favorable cultures is a form of biological fitness. Culture is an amazing mechanism for group adaptation to environments that biology alone couldn’t do in any reasonable amount of time. The design and cohesion of the culture that best resolves problems of communal life in that particular environment influences which genes are transmitted to the future. In some ways, culture necessarily shapes the very nature of what it means to be human, now and forever.

What’s Next?

Okay, that’s my explanation of what culture is and what factors drive its persistence. In part two, I will talk about what makes some people attached to culture and why some fight to empower their culture over others. I will look at how different individuals and communities perceives threats and in what ways those threats invoke cultural devotion. And, I’ll introduce how social hierarchy influences the whole business of culture, and how

And, eventually I’ll give you a function definition of the slippery term “group” so you don’t rebuke me.
