The older I grow the more I distrust the familiar doctrine that age brings wisdom. — H.L. Mencken

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Author: H.L. Mencken

Insight: We like to imagine that getting older automatically downloads wisdom into our brains—that the years just pile up and suddenly we understand things. But Mencken's skepticism points to something real: age mostly just gives you more experience being confidently wrong. Someone who's been in their field for thirty years isn't necessarily wiser than someone halfway through; they might just be better at sounding certain. The real problem is that familiarity breeds its own kind of blindness. The longer you've done something one way, the harder it becomes to question whether that way still makes sense. You accumulate opinions that feel like facts because you've held them so long. Meanwhile, someone younger might ask the obvious question you've stopped seeing. Wisdom isn't just about having lived through stuff—it's about staying willing to learn from it, and that gets harder as our habits calcify. This matters now more than ever, when experience and fresh thinking keep pulling in opposite directions. The most useful people aren't necessarily the oldest or the youngest, but those rare ones who've learned something without letting it close their mind.
