Single-neuron truth editing only fixes the lie it was trained on, chart shows

Sauers_ · x · 2026-10-20

A follow-up on research into editing models to tell the truth: the author notes the technique doesn't generalize to other narrow-liar organisms. The heatmap shows that editing the best single neuron for one lie topic (e.g. Battle of Lepanto) boosts truthful answers only on that topic (+50 percentage points), with near-zero effect on others (Treaty of Utrecht, The Rite of Spring) and even a -32 regression on The Night Watch — suggesting single-neuron honesty edits are highly topic-specific rather than a general alignment fix.
