Conjecture
Henrich's manioc case puts the best of cumulative culture beyond anyone's understanding: Tucanoan processing removes cyanide by steps whose function no practitioner can infer, and a learner who drops the steps she cannot justify still removes the bitter taste, so nothing tells her she has failed until her family sickens years later. This cuts against our habit of treating legibility as the route to correction. A collective that prunes practices it cannot ground will delete working know-how, and the feedback that would expose the loss arrives too late to be traced to the change.

groundsSource document
Often, most or all of the people skilled in deploying such adaptive practices do not understand how or why they work, or even that they do anything at all.
