To guess is to admit not knowing in the first place.
The problem with Dilbert’s coworkers and with most managerial teams is resisting to admit they don’t know. Even horoscopes and guesswork should start with the acknowledgment of a knowledge gap. Without such an acknowledgment, the time and effort needed to formulate and solve a problem is not justified. To guess is then to pretend knowing.
Guesswork supersedes learning from data because there is nothing to learn when it is all known. Successful data centric companies need a culture that encourages not knowing as much as knowing.
