Changing your mind isn’t weakness – defending wrong beliefs is
Changing your mind is supposed to be a failure.
That’s the cultural story, anyway. Politicians get destroyed for “flip-flopping.” In arguments, the person who changes their position is often seen as weak, inconsistent, untrustworthy. We treat the unchanged mind as the principled one and the changed mind as the compromised one.
This is backwards.
Changing your mind in response to evidence is exactly what rational thinking is supposed to produce. Refusing to change your mind when evidence demands it is the failure. We’ve just built a culture that rewards the latter and punishes the former, and most people absorb that culture without questioning it.
The person who holds the same position regardless of what the world does or what new information shows up isn’t principled. They’re stuck.
Cognitive dissonance from Essay 7 explains part of why this happens. When new information conflicts with what somebody already believes, it creates genuine psychological discomfort. The most common response is to resolve that discomfort by rejecting the new information – finding flaws in the evidence, questioning the source, dismissing the messenger – rather than updating the belief. The belief was there first and it’s attached to identity. The evidence is new and threatening.
So the evidence loses. The belief stays. The discomfort goes away.
Motivated reasoning makes this worse. People don’t just passively receive information. They process it through the filter of what they want to believe. Brains are sophisticated enough to construct elaborate justifications for positions that were arrived at emotionally. Smart people are often worse at this, not better – they have more tools for rationalization, more articulate ways to defend what they already think.
And most people never notice they’re doing it.
So how do you actually change your mind when the evidence says you should?
Separate your beliefs from your identity. If believing X is part of who you are – if somebody is “a person who believes X” rather than “somebody who currently thinks X based on available evidence” – then evidence against X is a personal attack. Make the separation explicit. The belief is something you hold. It isn’t the thing that holds you.
Get clear on what would change your mind before you encounter the evidence.
If somebody can specify upfront what evidence would shift their position, they’re being honest. If they can’t – if the answer is “nothing could convince me” – they’re not holding a belief. They’re holding a commitment. Those are very different things, and commitments don’t update no matter what happens in the world.
This is a useful question to ask other people too.
When somebody’s defending a position, ask them what would change their mind. Not to trap them – genuinely, to find out whether you’re in an argument or an immoveable standoff. If the answer is nothing, the conversation isn’t actually about evidence. It’s about loyalty. Those conversations are fine. They just aren’t arguments.
Practice on low-stakes things.
Change your mind about a restaurant recommendation. A movie you dismissed without watching. A route you always take that might not actually be the fastest. An assumption about a coworker that stopped being true years ago. Build the muscle on things where ego isn’t really on the line, because the muscle you build there is the same one you’ll need when the stakes are higher.
Want to be right more than you want to have been right.
Those are different goals, and they pull in opposite directions. Wanting to be right means you update when the evidence calls for it, because your loyalty is to accuracy. Wanting to have been right means you defend past positions to protect the story of yourself as somebody who doesn’t make mistakes. One leads to better thinking. The other leads to a museum of dead beliefs you keep guarding.
And watch the difference between updating and performing.
Some people go the other direction and make a production out of changing their mind – the big public announcement, the long essay, the identity shift. That’s often not actually updating. That’s shifting one performance for another, usually in the direction of whatever’s getting more applause right now. Real mind-changing is quieter. It looks like somebody noticing they were wrong, adjusting, and moving on. Not a conversion story. Just an update.
The uncomfortable part is that changing your mind well requires being okay with the fact that the old you was wrong.
Not stupid. Not a bad person. Just wrong about this specific thing, and capable of being wrong about other things too. That humility is the actual skill. Everything else is decoration.
People who can change their minds well are the ones you can actually talk to about hard things.
People who can’t are just waiting for you to stop talking so they can say the thing they were going to say anyway.
Be the first kind.
