Public Information: From Nosy Neighbors to Cultural Evolution
Étienne Danchin,1Luc-Alain Giraldeau,2Thomas J. Valone,3Richard H. Wagner4
Psychologists, economists, and advertising moguls have longknown that human decision-making is strongly influenced by thebehavior of others. A rapidly accumulating body of evidencesuggests that the same is true in animals. Individuals can useinformation arising from cues inadvertently produced by thebehavior of other individuals with similar requirements. Manyof these cues provide public information about the quality ofalternatives. The use of public information is taxonomicallywidespread and can enhance fitness. Public information can leadto cultural evolution, which we suggest may then affect biologicalevolution.
