Open Unknowns (2)

Unknown Does social network homophily causally produce echo chambers and political polarization, or do pre-existing attitude differences drive both homophily and polarization simultaneously? u-homophily-echo-chamber-causality
Unknown Whether network centrality measures (betweenness, eigenvector) causally determine socioeconomic outcomes or merely correlate with them, and whether targeted network interventions can increase social mobility by changing individuals' centrality positions u-social-capital-causal-vs-correlational

Active Hypotheses

Hypothesis The assortativity coefficient of political belief networks quantitatively predicts the within-community vs between-community information spread rate ratio, such that networks with assortativity r > 0.5 show misinformation spreading 10× faster within communities than between, creating measurable belief divergence within 30 days. high
Hypothesis Betweenness centrality (structural holes / brokerage position) in social networks mediates intergenerational income mobility: individuals who bridge disconnected social classes have higher upward mobility, and this effect is partially causal, as shown by interventions that create cross-class network connections high
