Claims / C-595FCFRQ15

EmpiricalRequires evidence

The most valuable practices often work for reasons no practitioner can state, so a learner who drops the steps she cannot justify, as with manioc detoxification, causes harm that surfaces only years later.

How groups think together

    Thus, the unwillingness of this mother to take on faith, the practices handed down to her from earlier generations would result in sickness and early death for members of her family. Individual learning does not pay here, and intuitions are misleading.

  • 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.

  • groundsSource document

    The problem is that the steps in this procedure are causally opaque. An individual cannot readily infer their functions into relationships or importance.

Replaces

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.

Why. One-sentence rewrite for sprint S-EK48QQ5S0N: the old paragraph mixed the book's finding with our inference; this keeps the finding as one bet, same quotes.
