Large language models often succeed on one formulation of a problem while failing on an equivalent formulation. Whether these failures arise from distinct internal circuits or different activation states of a shared circuit remains unknown. This study investigates whether arithmetic heuristic neurons are form-invariant across symbolic arithmetic, natural language word problems, and Python code in Llama-3 models. Using a two-stage pipeline of attribution patching and activation patching, we identify a compact set of neurons shared across all formats. Targeted interventions show this shared circuit is necessary and sufficient for late-layer arithmetic computation. Transferring activations from successful to failed executions recovers over 97% of errors for addition and subtraction, indicating cross-format failures arise from activation states rather than distinct circuits. Shared neurons consistently belong to the same heuristic families, demonstrating neuron-level form-invariance.

A new study uses a simple car-wash question to reveal that language models often pre-commit to an answer before reasoning, failing to derive logically correct conclusions. Experiments on Qwen3-8B show systematic wrong commitments (recommending 'walk' when 'drive' is the only valid option). Activation-level analysis suggests hidden states already lean toward the wrong answer before output, even for rollouts that eventually answer correctly. The findings highlight a pre-reasoning decision bias in LLMs.
