How Often Should You Change Your Mind? (More Than You Do)

I’ve been thinking about a strange asymmetry. The people I most respect at work change their minds a lot. The people I respect least change them almost never. And yet the cultural reward goes to consistency. “He’s a man of his word.” “She never wavers.” “They stick to their guns.”

We talk about steadfastness like it’s a virtue. Sometimes it is. Often it’s just intellectual laziness wearing a nicer outfit.

Adam Grant’s Think Again makes the case that rethinking is a skill - and like most skills, most people have it under-practiced. His framing is good, but I’ve been turning over a different angle on it: how often, in actual operational terms, should you change your mind? What’s the right cadence? Because “rethink everything constantly” is bad advice and “stick to your convictions” is also bad advice, and the truth is somewhere in a more uncomfortable middle.

The two failure modes

Let me sketch the two extremes so we can talk about the middle.

Failure mode one: the dogmatist. Has opinions formed at 28 and is still operating on them at 48. Treats consistency as identity. Updates are taken as betrayals of the prior self. When evidence contradicts the position, the evidence is the problem.

Failure mode two: the weathervane. Changes their mind with every new podcast, every new book, every new take from someone they respect. There’s no consistent position to update against, because nothing has settled long enough to constitute a position. Confuses openness with not thinking.

Most people I know are firmly the first. A smaller number - usually younger, more online - are the second. Both are stuck in different ways. Both are equally distant from anything you’d call good thinking.

The interesting question isn’t “should you change your mind?” It’s “how often, on what kinds of things, and how do you tell the difference between updating and drifting?”

Things you should change your mind about often

Some things have short half-lives. Updating frequently isn’t intellectual instability - it’s honesty about how fast the underlying facts move.

Tactical opinions about your work. What tool you use. How you onboard clients. The structure of your day. These should be updated roughly every six months. If you’re doing the same thing the same way two years on, you’re not consistent - you’ve stopped paying attention.

Predictions about specific people, projects, or markets. New evidence comes in constantly. If your assessment of a client, a launch, or a market trend hasn’t moved in six months, you’ve stopped looking. The world doesn’t pause to confirm your initial read.

What you think you want. This one is harder to admit. Most of us hold our wants like they’re fixed when they’re actually shifting underneath us. The thing you wanted from your career at 30 is probably not what you want at 35. Refusing to notice is how people end up successful at lives they didn’t actually choose.

For these, the question shouldn’t be “have I changed my mind?” It should be “when’s the last time I actually re-examined this?” If the answer is over a year, you’re due.

Things you should change your mind about slowly

Other things have longer half-lives, and constant updating is a sign of unsteadiness rather than rigor.

Core values. What matters to you. What you believe is right. These should change - they’re not fixed at 22 - but they should change slowly, in response to genuine experience, not last week’s podcast. If your values are getting rearranged every other month, they were never quite values.

Your read of your own strengths. People often update this too fast based on a single failed project or a single piece of harsh feedback. The pattern that matters is the pattern across many data points, not the most recent one.

Long-term relationships. Your assessment of a person you’ve known for ten years shouldn’t change because of one weird interaction. It should change based on accumulated patterns, slowly, over time.

The right cadence here is years, not months. And the test is: am I updating because of new information, or because of new emotion?

The diagnostic question I keep coming back to

When I notice myself about to change my mind on something, I ask: if I were arguing the opposite of what I’m currently moving toward, would I be just as persuaded by the next thing I read?

If yes - I’m not updating. I’m being moved by whatever’s loudest. Same nervous system reaction, just toward a different direction.

If no - there’s actually some signal in this update. New information, new pattern, something that genuinely changes the calculation.

This isn’t a perfect test. But it’s a useful gut check. Most of the time when I notice it, I realize I’m reacting to whoever I just talked to, not to anything actually new. The cure is usually waiting a week. If the update still feels right then, it probably is.

The professional cost of stubbornness

The reason any of this matters operationally is that stubbornness is expensive in modern work.

If you build your career around opinions you formed early, you’ll be charging 2018 prices in 2026. You’ll be using 2020 tools to solve 2026 problems. You’ll be pitching 2019 services to a market that’s moved on.

I’ve watched smart, talented people lose entire careers to this. Not because they were bad at the work. Because they refused to update their model of the work. They kept doing the thing they’d been good at, even as the world stopped paying for it the same way.

This is the underrated argument for rethinking. It’s not a virtue. It’s a survival mechanism for people whose work depends on being roughly in sync with reality.

Books that taught me to think clearly under pressure covers some adjacent ground - systems thinking is rethinking applied to how things connect. The basic muscle is the same.

Stubborn founders and opinion-attached creators

Two groups are especially bad at this, in my experience.

Founders, because their identity gets tangled with their original thesis. Changing the thesis feels like admitting the company was wrong, which feels like admitting they were wrong. So they double down on a vision that’s slowly diverging from reality. The founder who built a great pivot is rare partly because the pivot requires letting go of the original conviction.

Creators, because their public positions become their brand. Once you’ve published the take, you’re slightly trapped by it. The followers come for that take. Updating publicly feels like betraying them. So you keep performing the original view long after you’ve outgrown it privately.

The version of “changing your mind” that actually works for both groups isn’t a dramatic public reversal. It’s smaller and quieter - a gradual public evolution, where the position shifts a few degrees per year, in line with the actual thinking. The dramatic reversals are usually too late. The gradual updates are how it should have been all along.

I’ve covered some of this from a different angle in things I changed my mind about in 2025. The point of that post isn’t the specific things. It’s that the public list exists at all - that the habit of saying “I was wrong about that, here’s what I think now” is part of the practice.

A working answer

So how often should you change your mind?

Tactical positions: at least twice a year. If you can’t name a tool, process, or working theory you’ve reversed on in the last six months, you’re not paying attention.

Strategic positions: every 18-24 months, deliberately. Set a calendar reminder to ask: “are the things I’ve been assuming about my work and life still true?”

Core values and long-arc beliefs: rarely. Years. And when they do move, they should move because of cumulative experience, not because of a single book.

The skill isn’t changing your mind a lot. It’s changing your mind on the right things at the right pace, and noticing when you’ve stopped doing it on something that needs it.

The people who do this well aren’t impressive in any obvious way. They don’t post about it. They don’t make a big deal of it. They just quietly stay roughly in sync with reality while everyone else falls behind on whichever piece they’re refusing to update.

That’s the underrated edge. Not boldness, not consistency. Calibrated rethinking. Slow on the deep stuff, faster on the surface, and honest about which is which.

It’s not glamorous. It’s the difference between a career that compounds and one that ossifies. Worth more than the consistency we keep rewarding.
