Methodological Diversity
The deliberate use of methodologically distinct approaches by independent teams in a blind-replication protocol, ensuring that any agreement cannot be attributed to shared algorithm bias.
Methodological diversity is the deliberate use of methodologically distinct approaches by independent teams in a blind-replication protocol, designed so that any agreement between teams cannot be attributed to shared algorithm bias or shared assumptions. The Event Horizon Telescope paired CLEAN-based imaging pipelines (the Americas and Global teams) against Regularized Maximum Likelihood pipelines (the East Asia and Cross Atlantic teams) precisely so that convergence on the M87* image would carry evidential weight beyond what shared-methodology agreement could provide. See integrity-through-convergence and blind-analysis.
