Why do you assume a random DuPont agriculturalist, who pushes papers all day, understands food better than a professional farmer our their in the empirical field?
Back in the real world, BigCo agriculturalists also go out into the literal field. I used to work for a company that did agricultural telemetry, and our clients were big and small, and our BigCo contacts were frequently contacting us from somewhere other than an airconditioned office.
Why do you assume that professional farmers out in their empirical fields aren't intensively trained in much the same manner as the employees of Dupont? People get degrees in agriculture.
