+## Introduction
+Reasoning-augmented models sometimes fail by generating **overly short**, abstract chain-of-thought (CoT) reasoning, hurting their accuracy.
+**ThinkEdit** is a lightweight weight-editing method that:
+- Identifies ~4% of "short reasoning" attention heads
+- Edits only ~0.2% of total parameters
+- Removes the "short reasoning" direction from their output
+- Boosts performance, especially on cases with short reasoning traces
