Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026Fission-fusion dynamics implies distributed information processing analogous to that occurring in "liquid brains." Collective intelligence through complementary knowledge sharing! 🧠✨ Collaborators:Ross S. Walker, @mattjsilk.bsky.social, Denis Boyer and @sandrateles-esmag.bsky.social 020
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026Maximal simplicial degree centrality shows sigmoidal scaling with simplex size: intermediate-sized simplices (4-6 individuals) are most central to the network. Centrality is independent of age, sex, or immigration status → knowledge asymmetry driven by mobility, not individual traits. 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026These holes persist across multiple filtration values, indicating robust complementarity. Even when including less redundant interactions, spatial overlaps don't form trivial structures - unique knowledge pockets remain across various subset sizes. 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026We constructed filtered simplicial complexes using α as a filtration parameter (scaled by deviation from w*). Persistent homology reveals topological holes, which we interpret as structural signatures of complementary information distribution 🕸️ 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026We found that in some cases, the observed w values closely follow the predicted convex decreasing function of set size n. Smaller sets (2-6 individuals) show higher variance, suggesting this range is most dynamic for knowledge complementarity. 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026We derived an optimal intersection/union ratio (w*) that maximizes information transfer between n individuals: w* = 1/(n+1) This balances redundant overlap (coincidence opportunities) with unique knowledge (areas known exclusively by subsets). 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026We estimated individual core ranges (60% utilization distributions) from 6 years of location data in Yucatan, Mexico. We assumed that these core ranges represent an individual's spatial knowledge for a given season, while partial overlaps create opportunities for information transfer. 100
Gabriel Ramos-Fernandez @grf.bsky.social · 09/01/2026Spider monkeys (Ateles geoffroyi) exhibit high fission-fusion dynamics - individuals form subgroups that join and split frequently. We asked whether distributed spatial knowledge across individuals enabled collective processing of foraging information beyond individual capacity. 100
