I tried making an LLM generate different titles for a given article and compared their ranking scores. There seems to be a lot of variation in the ranking scores based on the way the title is worded. Titles that are more likely to generate 'outrage' seems to be getting ranked higher, but at the same time that increases is_hn_flagged score which tries to predict if a entry will get flagged.
i.e. do HN users upvote more based on the title of the article or on actually reading them?
