Abstract

fetched live from OpenAlex

In this study we used social network analysis of incel-related videos on YouTube to understand the recommendations, patterns, and dissemination of incel ideology on a popular multimedia platform, i.e., YouTube. Results revealed 12 distinct groups in the network (e.g., Female Hypergamy, Gynocentric Bias). Central videos in each group revealed the spread of ideological material on YouTube. Videos with the highest betweenness centrality scores were evaluated to map the pathways from groups with more innocuous video content to groups with more extremist incel-ideological content.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
