They also live in societies characterized by examples of cooperation of unmatched complexity, such as organized armies, the cooperative building of infrastructures such as roads and railways, and tax-paying, among others. (We exclude, of course, the ‘‘anonymous’ ’ societies of some social insects in which the animals themselves are not aware of the cooperative roles they play.) The emphasis on these unique aspects of our behavior 1 has sometimes distracted scientists from paying attention to the more common aspects of our daily lives, which share characteristics with those of our fellow primates. We invite friends for dinner, console others after a loss, intervene in ongoing fights, and even groom others. 2–4 These small acts of altruism, which constitute a large part of our daily social life, tend to resemble those of nonhuman primates.

Moreover, tourists are becoming increasingly sophisticated and discerning, and destination choice is now a considerable indication of lifestyle and a way to express identity. Thus, destinations robust. The method we use allows us to test in a simple way whether identical hotels with identical characteristics and seasonality differing only in their destination are priced differently in their room price. We control for a set of hotel characteristics and use the well-known Oaxaca-Blinder decomposition.1 Our results indicate*Correspondence to: Dr. Josep Raya Vilchez, Escola Univer-
