Human behavior and decision making

Josep Perelló

We investigate the behaviour of each individual in relation to his own benefit and the collective benefit. We use the infrastructure of the Board Games Festival DAU Barcelona to empirically find answers about humans’ behaviour through games and social dilemmas. We develop and design on digital platforms collective experiments to follow the humans’ decision making.

The first experiment of this project was conducted during the DAU in Fabra i Coats (Barcelona, 15 and 16 December 2012). The experiment is based on a model of conflicts that has been studied in detail to model, analyse and/or solve many real world situations: the prisoner's dilemma.

In the next edition (14 and 15 December 2013), we developed "Mr. Banks, the stock exchange game". Based on information related to the financial markets, the participants were asked if they think that the market will rise or fall. The game is available on line

In 2014, we proposed a new character called Dr. Brain, to study human behavior in an ample suite of games: prisoner's dilemma, harmony, stag-hunt and snowdrift games. We there explored the behaviour of subjects accross these ample collection of social dilemmas.
