My research has investigated a variety of topics in human cognitive evolution. I have examined, for instance, the question of how risk taking differs across different domains of everyday life, how it should be defined and measured, and how an evolutionary perspective can help explain why young men in particular are very risk prone. My present research focuses on cognitive adaptations underlying decision making under uncertainty in foraging. I have investigated whether the same mechanisms animals use in foraging for patchy resources are also shared by humans and used in novel tasks such as searching for physical resources or information on the Internet. I am also currently investigating whether people bring to bear heuristics or assumptions about the patchiness of resources and whether these underlie certain well-known phenomena of human judgment, such as the “hot hand” fallacy. In this research, I have expanded my methods to include cross-cultural comparative experiments in a foraging society in Amazonian Ecuador. I am an active collaborator with researchers in adjacent disciplines and regularly interact with other fields of psychology by applying my findings, for example, to research in developmental and clinical psychology.
