Decomposition-resistant representations appear in both neural networks and psychotherapy outcome research

summary

Both neural network representations and psychotherapy outcomes resist decomposition into independent factors, suggesting a shared structural property of complex adaptive systems.

In mechanistic interpretability, SAEs succeed locally but fail to provide global decompositions. In psychotherapy research, treatment outcomes resist decomposition into specific technique effects (the 'dodo bird verdict'). Both phenomena may reflect a shared property: complex systems that optimize for multiple objectives simultaneously develop representations that are irreducibly entangled.

supports · claim

SAEs function as local atlases on a non-globally-separable manifold

The SAE local atlas claim directly supports the decomposition resistance interpretation.
