Regular errors are unconditional, meaning that they incorporate model selection uncertainty. Outcome is a 3-level categorical variable: `P2 did not steal' = player 2 didn't steal; `P2 stole no DI' = player two stole but this didn't result in P2. We incorporated scenarios C and D to additional delineate two disadvantageous inequality for P1; and `P2 stole DI' = player 2 stole and this resulted in in disadvantageous inequality for P1. For outcome, 'P2 didn't steal' was the reference level. Estimates from the very same model when the reference level for outcome is ' P2 stole no DI' presented in S3 Table). doi:ten.1371/journal.pone.0159769.tA non-negligible proportion of players have been prepared to incur a cost to harm their partner, even when their companion did not steal any cash (Fig 1). The tendency to pay to harm a nonstealing (and even an overtly cooperative) partner has been observed in numerous other studies (e.g. [2, 22, 27?0, 39?3], exactly where it has variously been described using the labels 'antisocial punishment' or 'spite'. For ease, we are going to stick together with the term 'antisocial punishment' to describe the punishment of a non-stealing partner within this paper. Even though antisocial punishment was more common amongst the India-based than the US-based subjects, Indian subjects were usually much more punitive than US-based players in all treatment options and scenarios.Fig 1. The proportion of P1 who punished when P2 didn't steal (`Didn't steal'), P2 stole however the stealing did not outcome in disadvantageous inequality (`Stole no DI') or P2 stole along with the outcome was disadvantageous inequality for P1 (`Stole DI'). Information are shown for players primarily based in a) the USA and b) India. Error bars show the 95 binomial self-confidence intervals (Agresti-Coull process). Sample sizes for each and every situation are indicated in parentheses.

Cross-cultural variation in antisocial punishment is thought to be predicted by weak rule of law, that is itself negatively linked to Gross Domestic Item (GDP) [30]. In line with the Globe Bank [44], title= rstb.2015.0074 in 2013 the GDP of your USA title= geronb/gbp074 was 16,800,000 million dollars, compared with 1,876,797 million dollars for India in the same year.Contrast, punishment was improved when stealing resulted in disadvantageous inequality for the punisher.PLOS 1 | DOI:ten.1371/journal.pone.0159769 August 3,7 /Motivations for PunishmentTable 2.
