One question has quietly changed the way I think about almost everything:
Why do I believe this?
Notice that it isn’t asking whether a belief is true. It asks something much more fundamental: What produced this belief in the first place?
Those are not the same question.
We like to think we arrive at our beliefs by standing at the edge of a vast library, carefully weighing every idea before deciding what we think. Research suggests our journey is often much more human than that.
Political scientists have found that many people first connect with a political party through a single doorway: an issue they care about, a leader they admire, a family tradition, or a community where they feel understood. Once inside, they’re exposed to a much broader collection of ideas. As those ideas become familiar, through conversations, news, books, podcasts, and shared experiences, many gradually begin to feel self-evident.
Political scientist Gabriel Lenz found evidence that this process often works in reverse of what we imagine. Instead of agreeing with a party because we independently reached all of its conclusions, we often become attached to the party first and then come to adopt many of its broader beliefs over time.
Now ask a simple question:
Why do they believe what they believe?
If the answer is, “Because that’s what their group has consistently taught them,” then something important follows.
That doesn’t mean their beliefs are false.
It also doesn’t mean they’re true.
It simply means the reason they believe those things is not the same as evidence that those things are correct.
This distinction is easy to miss because our brains naturally blur the two together.
The origin of a belief and the truth of a belief are separate questions.
A person can arrive at a true conclusion for poor reasons. They can also arrive at a false conclusion after careful analysis. Understanding how a belief formed tells us something about its reliability, but it doesn’t settle the question of whether it matches reality.
I’ve found this to be one of the healthiest mental habits I can practice because it forces me to turn the question inward.
Instead of asking, “Why are they wrong?” I first ask, “Why do I believe I’m right?”
Was I persuaded by evidence?
Did I independently evaluate competing ideas?
Or have I simply absorbed the views of the people and information sources I’ve spent the most time around?
It’s one of the hardest questions we can ask ourselves because beliefs rarely exist in isolation. They’re woven into our identity, our friendships, our families, and the communities where we’ve found acceptance. To question a deeply held belief can feel like questioning whether we still belong.
That question is uncomfortable because none of us are immune to social influence. Every one of us inherits assumptions from our families, cultures, professions, communities, and experiences. The goal isn’t to eliminate those influences—they’re unavoidable. The goal is to become aware of them.
Once we understand where our beliefs came from, we can begin evaluating them on their own merits.
That is where genuine learning begins.
I’ve come to believe that intellectual humility doesn’t mean having fewer opinions. It means holding those opinions with enough curiosity that you’re always willing to ask one more question:
“Why do I believe this?”
