About us
Fermat's Library is a platform for illuminating academic papers. Just as Pierre de Fermat scribbled his famous last theorem in the margins, professional scientists, academics and citizen scientists can annotate equations, figures and ideas and also write in the margins.

A sequence of six 9’s (known as the Feynman Point) begins immediately after the 761st decimal place of π. Nobel prize-winning physicist Richard Feynman expressed a wish to memorize the digits of π as far as that point so that when reciting them, he would be able to end with “. . . nine, nine, nine, nine, nine, nine, and so on.”

This week's paper is "Categorizing Variants of Goodhart’s Law" by David Manheim and Scott Garrabrant. Goodhart's law is often stated as "when a measure becomes a target, it ceases to be a good measure". The authors note that there are various ways in which systems can fail when optimized excessively based on specific metrics. This occurs when a metric, initially useful for system improvement, is pushed to a point where further optimization becomes either ineffective or counterproductive. The paper argues that these failure modes are often misunderstood, partly due to unclear terminology and partly because discussions using this ambiguous language fail to distinguish between different types of failures within this broader category. Goodhart's law can be observed in action across diverse domains, including public policy, corporate management, and artificial intelligence alignment. In their paper, Manheim and Garrabrant examine several distinct failure modes, providing mathematical explanations to elucidate each type. Paper: https://buff.ly/3y0Oi2n
