Reading the Field's Own Claims
The idea
The technique: when a source quotes the delay between research and practice, establish which figure it is using, what that figure measured, and when — then read the claim against its own scope rather than as a fact about healthcare in general.
In practice
A paper opening with "it takes seventeen years for research to reach practice". The figure traced to a report published in 2000 that averaged across a broad range of health interventions. A later study found about fifteen years, across five cancer-control practices only — a narrower scope, quoted as though it were broader. Both figures noted as measuring time from publication to implementation rather than anything about the evidence itself. The companion claim that little published research reaches care recorded as widely agreed in direction and variable in magnitude. The paper's argument then read with its actual evidentiary weight rather than the weight the round number lends it.
Where people slip
A round number repeated for twenty-five years acquires authority its source never claimed. Both the seventeen-year and fifteen-year figures came from specific studies with specific scopes, and this course states both scopes for that reason.
