Identity Traps and Social Reasoning
@ZubyMusic: Politics can rot people's brains to the point that they'll oppose good ideas if they come from the 'wrong people' and support bad ideas if they come from the 'right people'
Tumblrino: I heard someone say the other day that most people's brains don't separate information into "true" and "false" but rather "us" and "them": will the people of my tribe approve of this? Then it's true. Will the people of my tribe disapprove and cast me out for expressing it? Then it's false.
This grabbed my attention because they're definitely referring to Dan M. Kahan's research on "Identity-Protective Cognition."
This paper supplies a compact synthesis of the empirical literature on misconceptions of and misinformation about decision-relevant science.
Most people think they update their beliefs based on evidence, but Kahan's research suggests otherwise and it's fascinating.
Identity-Protective Cognition is the tendency to selectively credit or dismiss evidence based on what your group believes, not what the evidence actually shows.
Among the ideas in this paper:
Being wrong is often the rational choice
If you change your mind on a "tribal" issue (climate change, gun control, vaccines, etc.) you risk social ostracism, family conflict, loss of status.
(Does that sound familiar?)
Being correct about a global scientific fact, meanwhile, has essentially zero effect on your personal life or the global outcome.
So your brain runs this calculation...and chooses the tribe.
Smart people are worse, not better
Kahan found that higher scientific literacy and reasoning ability actually increase polarization.
Smarter people, he says, are better at cherry-picking evidence and finding flaws in the other side's data. Their intelligence becomes a weapon for motivated reasoning, not a cure for it.
We don't just ignore inconvenient facts, we actively embrace misinformation that flatters us
Identity-affirming misinformation (stuff that makes your tribe look good) gets a free pass. Identity-threatening facts (stuff that makes your tribe look bad) get fought tooth and nail.
Kahan's proposed fix is information decoupling.
He says we need to separate the fact from the identity signal it carries.
Presenting correct information alone is useless and often counterproductive.
Kahan says you have to make the truth feel safe for someone's existing identity without implying they need to defect to the other side to believe it.
What Kahan is really describing is that humans are social animals before they are rational ones.
We evolved to survive in groups, not to optimize for abstract truth (to varying degrees.)
So our brains aren't broken, they're just running software thousands of years old in a world they didn't evolve to cope with.
None of this means minds can't change - they change constantly - but Kahan's research suggests the mechanism of change isn't argument or evidence. It's identity shift.
People change their minds when they find a new tribe, a new role model, or a way of seeing themselves that makes the truth feel like theirs.
And that insight might explain why identity politics tend to backfire
If you organize persuasion around group identity, you deepen the very grooves that make minds hard to change. You grow only rigid ideologues engaged in purity tests who are good at chanting on rhythm. They won't be created, nuanced, pragmatic, diplomatic, or effective communicators.
Yascha Mounk's The Identity Trap makes this case from a different angle.
When well-intentioned people make identity "the all-encompassing dividing line of American life," they aren't dissolving tribal thinking, they're institutionalizing it.
The result, Mounk argues, is an ideology that denies that members of different groups can truly understand each other. It squashes liberal pluralism.
That's precisely the condition that makes Kahan's trap inescapable.
The alternative Mounk points toward is very much like Kahan's: universalism.
Mounk says we need identities large enough to contain disagreement without triggering tribal self-defense.
His argument is that universal values, not group solidarity, offer the surest path to justice, fairness, and enduring social peace.
The model he holds up as effective is the civil rights movement. It wasn't an appeal to Black identity alone, but to a shared American identity, shared moral values, and a vision of humanity big enough that even those outside the group could feel called to it, not accused by it.
Dr. Martin Luther King Jr. didn't tell white Americans they were the enemy. He told them (and showed them) that they were falling short of their own ideals.
That's what a large identity looks like in practice. It isn't the erasure of difference, just a framework (built on words like citizen, neighbor, and human) where we aren't defined solely by the groups we were born into, but by what we can build together.
