We study the beliefs in a developed country about the attribution of responsibility for the situation in developing countries, in relation to helping behaviors and level of commitment. Two samples were used: one for the synthesis of knowledge (N=527) and a second for the synthesis of beliefs (N=287). From the results, we analyze the synthesis of beliefs and obtain the structure of beliefs. The synthesis of beliefs sample was made up of 137 individuals who help developing countries and 150 who do not. ANOVAs show that developed countries activate three implicit theories as beliefs to explain poverty in developing countries. Attribution external to the actor is more significant at higher levels of commitment to help. The implications for social communication campaigns in the developed world are discussed.
