TH EDITION EVOLUTIONARY PSYCHOLOGY, 5 Chapter x David Buss Chapter 12 Status, Prestige, and Social Dominance © 2015 by Pearson Education, Inc. All rights reserved. Emergence of Dominance Hierarchies • Dominance hierarchy – The fact that some individuals within a group reliably gain greater access than others to key resources—resources that contribute to survival or reproduction (Cummins, 1998) © 2015 Pearson Education, Inc. All rights reserved. Dominance and Status in Nonhuman Animals © 2015 Pearson Education, Inc. All rights reserved. Evolutionary Theories of Dominance, Prestige, and Status • An evolutionary theory of status must – Specify the adaptive problems that are solved by ascending status hierarchies – Explain why individuals accept subordinate positions within hierarchies – Predict which tactics people will use to negotiate hierarchies © 2015 Pearson Education, Inc. All rights reserved. Evolutionary Theories of Dominance, Prestige, and Status • Dominance – involves force or the threat of force • Schoolyard bully or a mafia “made man” may attain status through an ability to inflict physical punishment on others • Prestige – “freely conferred deference” © 2015 Pearson Education, Inc. All rights reserved. Prestige Signaling, Reputation, and Leadership • Individuals acquire prestige by displaying high levels of competence on tasks that groups value • Displaying generosity by giving more than taking • Making personal sacrifices that signal commitment to the group © 2015 Pearson Education, Inc. All rights reserved. Prestige Signaling, Reputation, and Leadership • One of the keys to prestige signaling is that others have to be aware of the signals in order to accord prestige to an individual • Leading and following can be viewed as evolved strategies for solving adaptive problems that involve group coordination such as coalitional hunting and coalitional defense, as well as for resolving conflicts that arise within the group © 2015 Pearson Education, Inc.

An Evolutionary Theory of Sex Differences in Status Striving • Elevated dominance and status can give males greater sexual access along two paths: – Dominant men might be preferred as mates by women • High-status men can offer women greater protection and increased access to resources that can be used to help support them, and their children, and perhaps even access to better health care (Buss, 1994b; Hill & Hurtado, 1996) © 2015 Pearson Education, Inc. All rights reserved. An Evolutionary Theory of Sex Differences in Status Striving • Women in polygynous societies often prefer to share with other cowives a bounty of resources that a high-ranking man can provide, rather than have all of the smaller share of resources held by a lower-ranking man (Betzig, 1986) – Dominant men gain increased access to women through intrasexual domination (Puts, 2010) • Dominant men might simply take the mates of subordinate men, leaving these low-ranking men helpless to retaliate © 2015 Pearson Education, Inc. All rights reserved. Leadership and followership: The service-for-prestige theory • Service-for-prestige theory of leader– follower relations – Leaders, according to this theory, provide key services to followers in the form of organizational skills, intelligence, wisdom, and knowledge in relevant domains – Fundamentally based on reciprocal altruism © 2015 Pearson Education, Inc. All rights reserved. © 2015 Pearson Education, Inc. All rights reserved. Status and Sexual Opportunity • Empirical evidence supports the evolutionary rationale for predicting a sex difference in the strength of the motivation to achieve high status • All available evidence suggests that high status in men leads directly to increased sexual access to a larger number of women © 2015 Pearson Education, Inc. All rights reserved. Status and Sexual Opportunity • Elevated status in women, of course, also could confer many reproductive advantages • But the direct increase in sexual access afforded men high in status suggests a more powerful selective rationale for a status-striving motive in men © 2015 Pearson Education, Inc. All rights reserved. Are Men Higher in Status Striving? • Men appear to score higher on attitudes endorsing getting ahead, including those that justify one person’s higher status than another and one group’s dominance over another © 2015 Pearson Education, Inc. All rights reserved. Dominance Theory • Dominance Theory – Humans have evolved domain-specific strategies for reasoning about social norms involving dominance hierarchies • These include: – understanding aspects such as permissions (e.g., who is allowed to mate with whom) – obligations (e.g., who must support whom in a social contest) – prohibitions (e.g., who is forbidden to mate with whom) © 2015 Pearson Education, Inc. All rights reserved. Dominance Theory – These cognitive strategies will emerge prior to, and separate from, other types of reasoning strategies – Selection will favor strategies that cause one to rise in dominance, but also will favor the evolution of subordinate strategies to subvert the access of the dominant individual to key resources © 2015 Pearson Education, Inc. All rights reserved. Dominance Theory • These strategies include: – – – – deception guile false subordination friendship, and manipulation, to gain access to the resources needed for survival and reproduction © 2015 Pearson Education, Inc. All rights reserved. Social Attention-Holding Theory • Social Attention-Holding Theory – Based in part on the concept of resourceholding potential (RHP) • RHP refers to an evaluation that animals make about themselves relative to other animals regarding their relative strengths and weaknesses – Animal might » attack the other, especially if it perceives itself to be superior in RHP » flee, especially if it perceives itself to be inferior in RHP © 2015 Pearson Education, Inc. All rights reserved. Social Attention-Holding Theory » submit—relinquishing critical resources to those higher in RHP – Dominance is not a property of an individual per se, but rather is a description of the relationship between two or more individuals – Proposes that humans have coopted RHP for another mode: social attention holding potential (SAHP) • SAHP refers to the quality and quantity of attention others pay to a particular person © 2015 Pearson Education, Inc. All rights reserved. © 2015 Pearson Education, Inc. All rights reserved. Social Attention-Holding Theory – According to this view, humans compete with each other to be attended to, and valued by, others in the group • When group members bestow a lot of high-quality attention on an individual, that individual rises in status • Ignored individuals are banished to low status – Differences in rank, according to this theory, stem not from differences in threat or coercion, but from differences in attention conferred by others © 2015 Pearson Education, Inc. All rights reserved. Social Attention-Holding Theory • Going up in rank produces two hypothesized consequences – Elation – An increase in helping • Plummeting in status has a different set of consequences for mood and emotion: – Onset of social anxiety – Shame © 2015 Pearson Education, Inc. All rights reserved. Social Attention-Holding Theory – Rage – Envy – Depression © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Verbal and Nonverbal Indicators of Dominance – Dominant individuals tend to • stand at full height, often facing the group, with hands on hips and an expanded chest • gaze a lot, looking at others while talking • do not smile much • touch others • speak in a loud and low-pitched voice • gesture by pointing to others © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance – Submissive individuals tend to • • • • stand bent rather than straight smile a lot speak softly listen while the other is speaking and give many deferential head nods • speak less than those who are higher in status • don’t interrupt others who are speaking • address the high-status persons in the group, rather than the group as whole © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • In a busy location in Vienna, Austria, one observer measured the pace of pedestrians. Later, a second observer interviewed each individual about his or her age, body height, and socioeconomic status – Significant positive correlations were found between walking speed and socioeconomic status for men © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance – For women, in contrast, there were no significant positive correlations • Size and Dominance – People prefer their leaders to be tall – Men who are tall believe themselves to be more qualified to be leaders and demonstrate a greater interest in pursuing leadership positions than shorter men © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance – Even with people we know personally, our mental image of their height is exaggerated if we know them to be high in social status – Tall men have an advantage in being hired, promoted, paid, and elected (Gillis, 1982) – Tall men earn higher salaries – In presidential elections in the twentieth century, the taller of the two candidates won 83 percent of the time © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Testosterone and Dominance – High T levels in men might lead to dominating behaviors that lead to high status in some subcultures, but reciprocally, elevations in status appear to lead to rises in T levels (Bernhardt, 1997) © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Serotonin and Dominance – The neurotransmitter serotonin joins T as one of the brain chemicals responsible for mediating one’s position in the status hierarchy © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Needed: A Theory of the Determinants of Dominance – Lacking is a comprehensive theory that can explain precisely what people value in others, why they value those things, and precisely why humans hold some people in esteem and awe while others remain ignored or are humiliated © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Self-Esteem as a Status-Tracking Mechanism – Sociometer Theory • Proposes that self-esteem functions as a subjective indicator or gauge of other people’s evaluations – An increase in self-esteem signals an increase in the degree to which one is socially included and accepted by others – A loss of self-esteem follows from a downward shift in the degree to which one is included and accepted by others © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance – Logic • Humans evolved in groups and needed others to survive and reproduce • This prompted the evolution of motivations to seek the company of others, form social bonds, and curry the favor of others in the group • Failure to be accepted by others would have resulted in isolation and premature death if one were forced to live without the protective covering of the group © 2015 Pearson Education, Inc. All rights reserved. Determinants of Dominance • Given that social acceptance would have been critical to survival, selection would have favored a mechanism that enabled an individual to track the degree of acceptance by others • That mechanism, according to sociometer theory, is self-esteem © 2015 Pearson Education, Inc. All rights reserved. Strategies of Submissiveness • The adaptive problems posed by being low in status – sex differences in submissive strategies – deceiving down – the downfall of “tall poppies” © 2015 Pearson Education, Inc.
