TL;DR
An empirical analysis of Hacker News content found roughly 65% of posts carry negative sentiment and those posts average higher points than the site mean. The pattern was consistent across six different classifiers, though the study does not establish causal direction between negativity and engagement.
What happened
A researcher analyzing Hacker News attention dynamics processed a collection of about 32,000 posts and 340,000 comments to measure sentiment and engagement. Using six different classifiers — three transformer-based models (DistilBERT, BERT Multi, RoBERTa) and three LLMs (Llama 3.1 8B, Mistral 3.1 24B, Gemma 3 12B) — they found a persistent negative skew: nearly 65% of posts were labeled negative. Negative posts averaged 35.6 points on Hacker News compared with an overall average of 28 points, a roughly 27% performance uplift. The author noted possible classifier calibration issues but observed the pattern across all models; results shared in a dashboard are based on DistilBERT for efficiency in a Cloudflare pipeline. The researcher characterizes most negative content as substantive technical critique rather than personal attacks and plans to publish a preprint on SSRN plus code, data, and a public dashboard soon.
Why it matters
- Negative-framed technical critique on a major tech forum correlates with higher measurable engagement.
- Findings could influence how researchers and platform managers think about attention dynamics and content ranking.
- Classifier calibration can affect sentiment distributions, so multilayer validation matters for empirical studies.
- Distinguishing substantive criticism from toxic content is important for moderation and community standards.
Key facts
- Dataset analyzed: ~32,000 Hacker News posts and ~340,000 comments.
- About 65% of posts were labeled as having negative sentiment across the study sample.
- Negative posts averaged 35.6 points on Hacker News versus an overall average of 28 points.
- Calculated uplift for negative posts is approximately 27% relative to the site average.
- Six classifiers were evaluated: DistilBERT, BERT Multi, RoBERTa, Llama 3.1 8B, Mistral 3.1 24B, and Gemma 3 12B.
- The negative skew appeared across all six models, although the score distributions varied.
- Dashboard outputs use DistilBERT in a Cloudflare-based pipeline for operational efficiency.
- The researcher described most negative posts as substantive technical critique rather than interpersonal abuse.
- A preprint is available on SSRN and the author intends to release code, the dataset, and a public dashboard.
What to watch next
- Release of the full code, dataset, and public dashboard from the researcher (planned but not yet published).
- The SSRN preprint for methodological details and robustness checks.
- Whether follow-up analyses address causality — i.e., whether negative framing drives engagement or attention attracts negative framing (not confirmed in the source).

Three transformer-based classifiers (DistilBERT, BERT Multi, RoBERTa) and three LLMs (Llama 3.1 8B, Mistral 3.1 24B, Gemma 3 12B).
How large was the dataset?
Approximately 32,000 posts and 340,000 comments from Hacker News were analyzed.
Will the code and data be available?
The author stated they will publish the full code, dataset, and a dashboard soon.
