In 2007 the psychologist Gerd Gigerenzer published Bauchentscheidungen, gut decisions. He is director emeritus at the Max Planck Institute for Human Development. The subtitle is Die Intelligenz des Unbewussten und die Macht der Intuition, the intelligence of the unconscious and the power of intuition. Gigerenzer argues that people make most decisions intuitively, by rules of thumb. In his view, following such gut decisions is itself a rational strategy, and good intuitions must ignore information. The magazine Bild der Wissenschaft gave the book its science book award.
The book does not praise haste. Gigerenzer separates a gut feeling from a random idea or from naivety.
