Some years later, Claude Shannon (also of Bell Labs) would consolidate many of the prevailing ideas on the subject in his 1948 paper "A Mathematical Theory of Communication" which would reference the work of Nyquist significantly.
To have our schools of communication (fairly new institutions) teaching technique as the do without regard for theory is tragic, though not unique to this discipline.
GPs would benefit from feedback about their manner, the quality and simplicity of their communication, their clarity in explaining diagnoses, treatments and next steps -thereby going beyond theory to learning by doing.
