Experimental Evidence for Attractions to Chance

Abstract

Divide the decision-maker's future into: (i) a pre-outcome period (lasting from the decision until the outcome of that decision is known), and (ii) a sequel post-outcome period (beginning when the outcome becomes known). Anticipated emotions in both periods may influence the decision, in particular, with regard to an outcome that matters to the person, the enjoyable tension from not yet knowing what this outcome will be. In the experiments presented, lottery choice can be explained by this attraction to chance, and cannot be explained by either convex von Neumann-Morgenstern utility, or by rank-dependent risk-loving weights: attraction to chance is a separate motivator.

Institutional choice versus communication in social dilemmas—An experimental approach

“…In those cases where defection occurred, the players in more than 50 percent of the cases extracted less than the maximum possible 2000 fish suggesting that the corresponding players wanted to defect without heavily diminishing the CPR in the case of success. This seemingly irrational behavior supports the notion put forth by Albers et al (2000), who argue that the mere existence of chance constitutes a source of positive utility that is independent of the structure of payoffs. At the same time, warm-glow effects are likely to have prevented excessive defection (e.g.…”

Excess entry in an experimental winner-take-all market

“…On the other hand, subjects could perceive the process of choosing the winner as not completely random and outside of their influence; that is, they have an "illusion of control" (Langer, 1975). Another possible explanation for excess entry is that people like the "thrill of competition" or experience an "attraction to chance" (see Albers et al, 2000). They might attach a higher value to a win in the game than just its monetary payoff.…”

'Excess Entry, Ambiguity Seeking, and Competence: An Experimental Investigation'

“…Similarly, many people -even with little talent -choose professions that allow them to demonstrate competence even if they fail to earn well let alone reach prominence (consider, e.g., the arts, academia, or professional sports). Finally, we also suspect that, as a group, entrepreneurs receive additional utility from the thrill of competition and/or experience attraction to chance (Albers, Pope, Selten, & Vogt, 2000).…”
