We have all done it argued a point we knew wasn’t quite right, ignored evidence that proved us wrong, or stubbornly stood by a belief long after it stopped making sense. Why? Why do smart, well-meaning people hold on to beliefs that don’t serve them or anyone else?
The truth is, humans aren’t built to seek truth above all. We’re built to survive, belong, and make sense of a messy world. And sometimes, that means hanging on to bad ideas. Let’s break down why this happens and how to spot it in yourself.
1. Beliefs Feel Like Part of Who We Are
Think about your deepest beliefs about religion, politics, relationships, success. They’re not just opinions you have, they’re part of who you are. Challenging those beliefs can feel like threatening your identity.
If you’ve grown up believing hard work always leads to success, being told otherwise doesn’t just challenge an idea it threatens your sense of fairness, your motivation, even your life choices. So, instead of changing the belief, we often reject the new evidence.
Why it matters: We’re not wired to easily change ideas that anchor our sense of self.
2. The Tribe is Stronger Than the Truth
We’re social animals. Fitting in is baked into our survival instinct. If your group believes something whether it’s a political stance, a conspiracy theory, or a parenting method—going against that can make you feel isolated or even rejected.
So we stay loyal to the group. We echo their ideas, defend their logic, and ignore contradictions—not because it’s right, but because it keeps us connected.
Why it matters: Being accepted by others can feel more important than being right.
3. Confirmation Bias: We See What We Want to See
Ever notice how you can Google anything and find an article that supports it? That’s confirmation bias in action. We tend to seek out and remember information that confirms what we already believe and dismiss what doesn’t.
If you believe social media is bad for kids, you’ll likely remember headlines that support that. If you believe it’s harmless, you’ll spot articles that agree. Both might ignore studies that say the opposite.
Why it matters: The mind filters information to protect what it already believes.
4. Changing Your Mind Feels Like Losing
We treat beliefs like debates something to win. So admitting we were wrong can feel like losing an argument, even if no one else is watching. It's uncomfortable. It dents our ego.
But here’s the twist: growth comes from that discomfort. Learning to say “I was wrong” is one of the most powerful things a person can do but it’s hard, especially if you’ve held a belief for a long time or defended it publicly.
Why it matters: Letting go of a bad belief can feel like defeat, but it’s actually a win for your future self.
5. Our Brains Love Shortcuts
The world is complicated. We can’t deeply analyze every idea that comes our way. So we use mental shortcuts rules of thumb, stereotypes, habits of thought to keep up.
These shortcuts aren’t always bad. They help us make decisions quickly. But they also lock us into simple, sometimes wrong, ways of thinking.
For example, believing “successful people wake up early” might lead you to ignore successful night owls or to blame yourself unfairly if you’re not a morning person.
Why it matters: Simple stories are comforting, but reality is messy.
6. We Invest in Our Beliefs
There’s something called the sunk cost fallacy when we stick with something just because we’ve already put time, money, or energy into it. Beliefs work the same way.
If you've spent years fighting for an idea, convincing others of it, or building your career around it, letting go feels like wasting all that effort. So we double down instead of backing off.
Why it matters: The more we’ve invested in a belief, the harder it is to let go even when we should.
So, What Can We Do About It?
Changing your beliefs doesn’t make you weak. It means you’re learning. Here’s how to loosen the grip of bad beliefs:
Get curious, not defensive. When something challenges your view, pause. Ask: What if this were true?
Talk to people who disagree with respect. Don’t argue to win. Listen to understand.
Follow the evidence even if it’s uncomfortable. Truth isn’t always convenient, but it’s freeing.
Be okay with changing your mind. It’s not losing it’s evolving.
