Researcher Personality

Each researcher in the topical-homophily cohort gets a four-letter type assembled from four career-stage-neutral axes. Cell counts give the population inside each of the 16 types; click a cell to filter the table to its members. The classification covers the researchers with a homophily score (≥3 coauthors with semantic communities).

16 personality cells (4×4 grid)

Rows: Mover/Stayer × Heterophilous/Homophilous. Columns: Broker/Local × Team/Solo. Click a cell to filter the table; click again to clear.

Who collaborates with whom (16×16)

For each ordered pair of personality types, the heatmap shows the coauthor edges between them. Switch between row share (what fraction of type-i's edges land in type-j) and lift (row share divided by type-j's population fraction; ×1 = chance).

Per-author profile

Default sort is by citations. Click a column header to re-rank. The four binary axes are shown as separate columns; the combined type is in the first column.
The Mover signal uses the §9 trajectory class when available (≥3 five-year bins after truncating the partial 2025–29 window), falls back to a simple Stayer/Mover cut on raw bins for authors with ≥2 observable bins, and defaults to Stayer for authors whose career history is too short to register movement. The Bridge axis is binary on weighted betweenness centrality (Broker iff bcw > 0); 78% of the cohort sits at bcw = 0 in this 32k-node graph, so brokerage is genuinely rare.
