The effect of uncertainty about the number of rounds the game will take is hence enlightened. For instance, how much time the players have to avoid the consequences of surpassing a dangerous verge. Surprisingly, the results indicate that, for low levels of this timing uncertainty, not only collective success does not decrease significantly, but they observe a behavioral shift. Contrarily to what happens when there is no uncertainty, participants invest earlier and in a more polarised manner.
Moreover, a behavioural analysis of the experimental data reveals that, under timing uncertainty, participants of successful groups tend to reciprocate in a similar fashion to the group analogous of the Tit-for-Tat strategy, where players only increase their investments if the group does the same. Such a result indicate that certain behavioral ecosystems are more successful than others in achieving the equilibrium that is socially optimum.
