The Decline in the Transmission of Scientific Ideas
The Decline in the Transmission of Scientific Ideas by Tyler Cowen July 27, 2026 at 12:18 am in Data Source Economics Science We document that the diffusion of new scientific ideas beyond their field of origin has declined substantially over the past four decades. This contraction is closely linked to increasing specialization in scientific language: research that employs more technical terminology tends to be adopted less broadly. We develop a theory of scientific discovery in which the diffusion of new ideas depends on the degree to which potential adopters can understand and process them.

This contraction is closely linked to increasing specialization in scientific language: research that employs more technical terminology tends to be adopted less broadly. We develop a theory of scientific discovery in which the diffusion of new ideas depends on the degree to which potential adopters can understand and process them. When introducing their discoveries, scientists face a tradeoff between technical communication targeted at their immediate peers and more accessible language meant to reach broader audiences.
