Interpretability researchers clash over whether readout-steering mismatch undermines representation analysis
rgblong · x · 2026-10-09
An X thread debating interpretability methodology: the author questions how to read a paper's findings—if readout results (when a direction is naturally active) serve as evidence about representation content while steering behavior shows how models respond to out-of-distribution nudges along it, then any "functional mismatch" seems like a problem for the analysis axis and/or setup. The counterpart argues these are meaningfully different signals; the author confesses this makes the paper's various findings even harder to construe.
