Humans differ greatly in their tendency to discount future events, but the reasons underlying
such inter-individual differences remain poorly understood. Based on the evolutionary …

How organisms discount the value of future rewards is associated with many important
outcomes, and may be a central component of theories of life-history. According to life …

Although theories from economics and evolutionary biology predict that one's age, health,
and survival probability should be associated with one's subjective discount rate (SDR), few …

Individuals exposed to deprivation tend to show a characteristic behavioral syndrome
suggestive of a short time horizon. This pattern has traditionally been attributed to the …

Background Why do some people live for the present, whereas others save for the future?
The evolutionary framework of life history theory predicts that preference for delay of …

We synthesized life history theory and the antagonistic pleiotropy hypothesis to form an
integrative framework for understanding delay discounting (DD). We distinguished between …

Why do some people take risks and live for the present, whereas others avoid risks and save
for the future? The evolutionary framework of life history theory predicts that preferences for …

Three societies, namely the hunter-gatherer, the agrarian and the industrial, represent the
course of human history of cultural and economic development. In this course, each society …

We explore the standard expected utility model and alternatives to it. We then examine the
behavioral and neurological evidence for hyperbolic discounting. We discuss evidence …

This study tested specific predictions of risk preference in human choice derived from
evolutionary hypotheses. The overall choice pattern revealed that subjects receiving a life …
