This paper presents the results of an experiment where people can reduce (`burn`) other subjects` money at a cost to their own, with the decisions of one of them (randomly chosen after all decisions are made) getting implemented to determine final winnings. Almost 50% of the subjects engage in...

A positive correlation between relative position and the neurotransmitter serotonin exists in non-human primates, within an optimal range. This paper explores the reasons of this correlation. The main function of serotonin appears cognitive: it determines how optimally agents perceive and behave...

The conjunction fallacy occurs whenever probability compounds are thought of as more likely than its component probabilities alone. In the experiment we present, subjects chose between simple and compound lotteries after some practice. Depending on the condition, they were given more or less...

An experiment on choices between single and compound lotteries is presented, and results are calibrated with neural network models. Many subjects tend to average out probabilities, though behaviour becomes more rational with more exposure to compound lotteries in the practice stage. The Prior...

Trust responsiveness is the tendency to fulfill trust because you believe that it has been placed on you. The experiment presented in this paper uses two simple trust games to measure directly or indirectly the robustness of trust responsiveness in three conditions: when beliefs are elicited and...
