“…While players are best reply reasoners when their beliefs about the action of the other is fixed (in line with the ratifiability assumption), they are not in presence of uncertainty. xiii Masel (2007) formalises the idea of ADB in a 'Bayesian model of quasi-magical thinking', and shows that in public good games a positive correlation between the players' contributions and their beliefs about the strategy of others can explain cooperative behaviours. Hammond (2009) also defended ADB as a case of 'rational folly', since although players know that their actions cannot directly influence the actions of others, they could be better off if they actually hold that belief: it would therefore be rational for them to hold irrational and false beliefs (see Lecouteux, 2015, propositions 11 and 12, for an evolutionary justification of 'rationally irrational' behaviours).…”

“…Although this characterization behavior is simple, it can allow for a rich analysis as a form of minimal cognition (Beer 2003) and we can associate a cognitive cost for this extra decision-making ability (Kaznatcheev 2010). Or push this genotype to behavior map even further (Kaznatcheev, Montrey, and Shultz 2014) by having evolving agents act rationally on their evolved perceptions of the game payoffs and (potentially-biased) estimates of other's probability to cooperate (for this direction, see also Masel (2007)).…”

“…42 Specifically, because in these models all Kantians or rule utilitarians evaluate strategies in the same way, any heterogeneity in nonstandard behavior is driven completely by asymmetry in the physical aspects of the game (e.g., variations in the cost of voting). In contrast, even in symmetric games, our model captures heterogeneity in behavior (e.g., in the sets of PD games that different players choose to cooperate in).43 Additional models in which players' beliefs about opponent play may be biased includeOrbell and Dawes (1991),Bernheim and Thomadsen (2005),Masel (2007),Capraro and Halpern (2015), alNowaihi and Dhami (2015).44 In addition, our behavioral model introduces the possibility of equilibrium multiplicity even in the PD, depending on F . It is then the axioms that rule out models with multiplicity, again showing that the second concern can also be addressed axiomatically.…”
