J-space auditing might be unreliable

Across these preliminary experiments, decoded J-space did not seem particularly informative about reward-hacking behaviour. The readouts remained substantially similar across checkpoints and monitoring conditions despite meaningful behavioural differences, and providing J-space to an LLM auditor produced little additional discrimination beyond the information already available from the task or transcript. These results are limited to one model family, one model organism, and one behavioural sett...
