About this episode

Alex Mallen discusses the risks posed by fitness-seeking AIs and proposes potential mitigations.

Current AIs routinely take unintended actions to score well on tasks: hardcoding test cases, training on the test set, downplaying issues, etc. This misalignment is still somewhat incoherent, but it increasingly resembles what I call "fitness-seeking"—a family of misaligned motivations centered on performing well in training and evaluations (e.g., reward-seeking). Fitness-seeking warrants substantial concern. In this piece, I lay out what I take to be the central mechanisms by which fitness-seeking motivations might lead to human disempowerment, and propose mitigations to them. While the analysis is inherently speculative, this kind of speculation seems worthwhile: AI control emerged from explicitly taking scheming motivations seriously and asking what interventions are implied, and my hope is that developing mitigations for fitness-seeking will benefit from similar forward-looking analysis. Fitness-seekers are, in many ways, notably safer than what I'll call "classic schemers". A classic schemer is an intelligent adversary with unified motivations whose fulfillment requires control over the whole world's resources. Meanwhile, fitness-seeking instances generally don’t share a…
