Epistemic Percolation

Epistemic percolation is the process by which beliefs, claims, or knowledge claims propagate through a network of interconnected propositions, agents, or institutions, crossing threshold densities at which local acceptance becomes global consensus — or local skepticism becomes systemic doubt. The concept imports the mathematical machinery of percolation theory and the giant component into epistemology, treating belief systems as topological structures with phase transitions rather than as accumulations of individually justified propositions.

The central insight is that belief formation is not linear. A claim does not become accepted gradually, as evidence accumulates point by point. Instead, acceptance behaves like a phase transition: below a certain threshold of supporting connections, the claim remains isolated — believed by a few, resisted by many. Above the threshold, it suddenly becomes part of the giant
