Claim That 8% of The Pile Is Christian Content Challenged: Keyword Method Miscounts Long Books

cis_female · x · 2026-09-18

An ICMI working paper by Tim Hwang estimated, via strict keyword classification on a 100,000-document sample of The Pile (825B tokens), that roughly 67 billion tokens (8.1%) are explicitly Christian content — 32x the Islamic share, 19x Buddhist, 45x Hindu, 93x Jewish, and equivalent to 15x English Wikipedia — proposing a "Christian Prior" hypothesis that frontier models' moral reasoning is by default shaped more by the Christian tradition than any other ethical framework.

However, @cisfemale challenges the methodology: Hwang counts a source as Christian if it hits a keyword threshold, and 90% of his "Christian" sources are just long books that mention Christianity in passing, not Christian books. If correct, the 8.1% estimate is significantly inflated, undermining the paper's quantitative case that the alignment community is neglecting a massive Christian prior in pretraining data.
