Thought Style Resistance to Displacement

A thought style is not a garment that can be removed and replaced. It is a perceptual architecture — a load-bearing structure supporting not merely beliefs but an entire way of being: professional identity, social networks, career investments, institutional affiliations, accumulated judgments a life's work has deposited. Displacing a thought style means displacing all of these simultaneously. The resistance is proportional to the investment, and the investment is typically enormous. Fleck traced the pattern through medical history, finding that the most experienced practitioners were invariably the most resistant to new frameworks — not because they were less intelligent than younger colleagues but because they had the most to lose. The price of accepting a new way of seeing was the devaluation of everything the old way had produced.
