Owain Evans: Claude's assistant persona maps to elite-school humans

morqon · x · 2026-09-16

Owain Evans shares a finding on model personas: during finetuning the assistant adopts traits from human characters it internally represents as resembling elite-school humans more than non-elite ones. He argues this is not explained by provenance-based trust, citing Slocum et al 2025 showing provenance doesn't matter for belief uptake from finetuning. tenobrus jokes this is 'figuring out which ivy league school Claude went to.'
