Social Decision Making

AbstractWhile there already is a huge body of research examining the advantages and disadvantages of physical attractiveness in social and economic decisions, little research has been made to explore the role of individual differences in social decision-making with regard to beauty. To close this scientific gap, we conducted a multiparadigm online study (N = 210; 52% females) in which participants were asked to make decisions in four different economic games facing differently attractive counterparts. Additionally, the personality trait agreeableness was assessed to test for individual differences in decision-making. In exploratory analyses, we also assessed which facet of agreeableness is the most appropriate to predict individual differences in the various economic games. In the study, we were able to replicate the finding of a beauty premium and a plainness penalty but did not find any support for the idea of a beauty penalty. Furthermore, evidence for an opposite-sex advantage was found, which was greater when men were facing women than the other way around. While agreeableness as an overall trait influenced decision making across various paradigms, interactions of distinct facets of agreeableness with the partners’ attractiveness remain heterogeneous and ambiguous. This underlines the importance of integrating the specificity of certain traits in experimental research and the necessity of combining them with different social situations.

Social Decision Making

As humanoid robots become more advanced and commonplace, the average user may find themselves in the position of wondering if their robotic companion truly possesses a mind. It is important for scientists and designers to consider how this will likely affect our interactions with social robots. The current paper explores how social decision making with humanoid robots changes as the degree of their human-likeness changes. For that purpose, we created a spectrum of human-like agents via morphing that ranged from very robot-like to very human-like in physical appearance (in increments of 20%) and measured how this change in physical humanness affected decision-making in two economic games: Ultimatum Game (Experiment 1) and Trust Game (Experiment 2). We expected increases in human-like appearance to lead to a higher rate of punishment for unfair offers in the Ultimatum Game, and to a higher rate of trust in the Trust Game. While physical humanness did not have an impact on economic decisions in either of the experiments, follow-up analyses showed that both subjective ratings of trust and agent approachability mediated the effect of agent appearance on decision-making in both experiments. Possible consequences of these findings for human- robot interactions are discussed.

Social Decision Making

AbstractShoals formed by many piscine species are fission-fusion societies where decisions to leave or join a group can have consequences on the fitness of individuals. Some important factors that determine shoal choice are shoal size, familiarity and species composition. However, individuals and species often exhibit distinct shoaling preferences. Individual differences in shoaling preferences may also be related to personality traits such as boldness and sociability. In this study, we examined the link between shoaling decisions and personality traits in a hatchery reared population of an endangered megafish, the Deccan Mahseer (Tor khudree). We found that this fish exhibits a distinct preference for larger shoals at ratios of 1:2 or greater. However, they did not prefer to associate with an isolated familiar individual over unfamiliar ones or with a member of their own species over an invasive species. Moreover, shoaling preferences in individuals did not correlate with their boldness or sociability. These results suggest that hatchery reared mahseers which are reintroduced into natural habitats may shoal with invasive species, negatively affecting their viability. Modifying social behaviour of mahseers by amending rearing practices may be a useful strategy to improve outcomes of restocking interventions.

Social Decision Making

As humanoid robots become more advanced and commonplace, the average user may perceive their robotic companion as human-like entities that can make social decisions, such as the deliberate choice to act fairly or selfishly. It is important for scientists and designers to consider how this will affect our interactions with social robots. The current paper explores how social decision making with humanoid robots changes as the degree of their human-likeness changes. For that purpose, we created a spectrum of human-like agents via morphing that ranged from very robot-like to very human-like in physical appearance (i.e., in increments of 20%) and measured how this change in physical humanness affected decision-making in two economic games: the Ultimatum Game (Experiment 1) and Trust Game (Experiment 2). We expected increases in human-like appearance to lead to higher rates of punishment for unfair offers and higher ratings of trust in both games. While physical humanness did not have an impact on economic decisions in either of the ex-periments, follow-up analyses showed that both subjective ratings of trust and agent approachability medi-ated the effect of agent appearance on decision-making in both experiments. Possible consequences of these findings for human-robot interactions are discussed.

Malicious Intent

Paranoia is the exaggerated belief that harm will occur and is intended by others. Although commonly framed in terms of attributing malicious intent to others, recent work has explored how paranoia also affects social decision-making, using economic games. Previous work found that paranoia is associated with decreased cooperation and increased punishment in the Dictator Game (where cooperating and punishing involve paying a cost to respectively increase or decrease a partner’s income). These findings suggest that paranoia might be associated with variation in subjective reward from positive and/or negative social decision-making; a possibility we explore using a pre-registered experiment with US-based participants (n=2,004). Paranoia was associated with increased self-reported enjoyment of negative social interactions and decreased self-reported enjoyment of prosocial interactions. More paranoid participants attributed stronger harmful intent to a partner. Harmful intent attributions and the enjoyment of negative social interactions positively predicted the tendency to pay to punish the partner. Cooperation was positively associated with the tendency to enjoy prosocial interactions, and increased with participant age. There was no main effect of paranoia on tendency to cooperate in this setting. We discuss these findings in light of previous research.

Gains And Losses

The role of the loss-gain context in human social decision-making remains heavily debated, with mixed evidence showing that losses (vs. gains) boost both selfish and prosocial motivations. Herein, we propose that the loss context, compared to the gain context, exacerbates intuitive reactions in response to the conflict between self-interest and prosocial preferences, regardless of whether those dominant responses are selfish or altruistic. We then synthesize evidence from three lines of research to support the account, which indicates that losses may either enhance or inhibit altruistic behaviors depending on the dominant responses in the employed interactive economic games, prosocial/proself traits, and the explicit engagement of deliberative processes. The current perspective contributes to the ongoing debate on the association between loss-gain context and human prosociality by putting forward a theoretical framework to integrate previous conflicting perspectives.

Social Decision Making

AbstractOutcome transparency and the weight given to social information both play important roles in decision making, but we argue that an overarching influence is the degree to which individuals can and do gather information. Evolution, experience, and development may shape individual specializations in social decision making that carry over across contexts, and these individual differences may influence collective behavior and cultural evolution.
