The many sorrows of our recent history suggest that we humans have a learning disability.

We're wired to forget history

There's something both sobering and oddly comforting in Sagan's observation. We watch the same conflicts repeat across centuries, the same biases resurface in new clothes, the same warnings go unheeded. It's tempting to feel hopeless about it—like we're fundamentally broken, unable to evolve past our worst impulses. But calling it a "learning disability" rather than pure evil or stupidity actually shifts something important. It suggests the problem isn't malice; it's capacity.

We struggle to learn from history partly because the lessons arrive too slowly and too distantly. A famine in a distant country, a war that ended before we were born, a mistake made by people we'll never meet—these don't land the way a burned hand does. We're wired for immediate feedback, not civilizational patterns. And there's another layer: even when we do recognize a pattern, institutional inertia, tribalism, and the sheer complexity of modern systems make change glacially slow. We can know something is wrong and still feel powerless to stop it.

The hopeful part is hidden in the diagnosis itself. Learning disabilities aren't permanent. They're edge cases in human cognition, not death sentences. It means the problem is solvable—just differently than we've been trying.
