Summary

In this conference, physicist and philosopher Etienne Klein addresses the question of whether knowledge is necessary for decision-making. He argues that excessive knowledge can lead to paralysis and that decisions are often made in the face of uncertainty. He critiques the Dunning-Kruger effect, which shows that incompetence breeds overconfidence, and discusses the changing perception of risk in modern society. He contrasts the historical belief in progress with the contemporary emphasis on innovation, which is often seen as risky and obligatory. Klein suggests that decision-making is facilitated not by knowledge alone but by a personal philosophy of history that clarifies what one wants. He also touches on the precautionary principle, noting its misuse in reducing anxiety rather than danger. Ultimately, he advocates for embracing risk and decision-making despite incomplete knowledge.
