Resumo: The possibilities of using behavioral economics as theoretical support for the design of public policies are explored, aimed at the furtherance and promotion of recreational and tourist activities in the town of San Nicolás Tetelco, Tláhuac, for which purpose a Randomized Controlled Trial was performed. Concepts such as loss aversion, perspective and results bias, nudge, signals and expectations, were used to design the experiment and analyze its results. A probabilistic questionnaire was applied to find out the motivations of the inhabitants, with that base two tourist routes were designed in the area (control and study), in which 20 and 22 people respectively participated. The findings of the study confirm: 1) the importance of the detailed design of interventions in human groups, as a mean to bring the results closer to their purposes and 2) that satisfaction levels improve when their expectations are close to the experience results, thereby reducing the hindsight bias.
