The โ€œEpstein Filesโ€ and the anatomy of hidden social networks How secrecy reshapes structure and why its analysis is conditional on the data

A lot of โ€œnetwork analysisโ€ about the Epstein Files.

Nearly all of them missing the point: when a system operates under strong incentives for discretion, what gets documented is NOT a neutral sample of reality.
Results are conditional on what is observed!
