People generally see what they look for, and hear what they listen for. — Harper Lee

People generally see what they look for, and hear what they listen for.

Author: Harper Lee

Insight: We like to think we see the world as it actually is, but the truth is far stranger—we mostly see what we've already decided to look for. If you're convinced your coworker doesn't respect you, you'll spot the eye-roll and forget about the three times they asked your opinion. If you're looking for signs that people are generally kind, you'll notice the stranger who held the door and barely register the one who didn't. This isn't cynicism or optimism winning out; it's just how attention works. Our brains are bombarded with far too much information, so they use our existing beliefs as a filter to decide what's worth noticing. The tricky part is that this filtering happens almost invisibly. You're not consciously ignoring evidence; you genuinely don't see it in the first place. So when two people experience the same situation and walk away with completely different stories, they're not lying or being stubborn—they're literally operating from different perceptions. The person convinced the world is unfair will find proof everywhere. The person looking for opportunity will too. This matters because it means change often starts not with convincing yourself to think differently, but with deciding what to actually pay attention to. What would you notice if you started looking for it?
