What does it mean to act rationally? Mr. Perfect (homo economicus) is an optimizer endowed with special foresight. He has his desires and his other assessments well ordered and aligns his decisions with these desires. However, Mr. Perfect has come under criticism. In the meantime, a Mrs. Smart has taken his place: she adapts smoothly to action environments and acts not optimizing but according to rules of thumb. Although she does not act “perfectly” but only “limitedly” rationally, she reaches better results faster in many cases.

Susanne Hahn is an associate professor of philosophy at the University of Düsseldorf, and in 2017 received for “Rationality. A Mapping” the Philosophy Prize of the Max Uwe Redler Foundation and is currently working primarily on artificial intelligence and ethics.
