Mirror, mirror on the wall: The effect of time spent grooming on wages

It is well understood that personal grooming provides an important source of communication about individuals, their values and personalities. From an economic point of view, grooming is a non-market activity. The standard view is that time spent in non-market activities is counterproductive as it reduces work effort and job commitment. But grooming is different. There is reason to believe that certain productive personality traits may be inferred on the basis of personal grooming. Using data from the American Time Use survey, we investigate whether workers who spend more time grooming earn higher wages. The evidence shows that while higher levels of grooming time increases wages for men, there is no significant effect on women’s wages. We also find evidence that the returns to grooming are even larger for minority males.

Characterizing Pedophile Conversations on the Internet using Online Grooming

Cyber-crime targeting children such as online pedophile activity are a major and a growing concern to society. A deep understanding of predatory chat conversations on the Internet has implications in designing effective solutions to automatically identify malicious conversations from regular conversations. We believe that a deeper understanding of the pedophile conversation can result in more sophisticated and robust surveillance systems than majority of the current systems relying only on shallow processing such as simple word-counting or key-word spotting. In this paper, we study pedophile conversations from the perspective of online grooming theory and perform a series of linguistic-based empirical analysis on several pedophile chat conversations to gain useful insights and patterns. We manually annotated 75 pedophile chat conversations with six stages of online grooming and test several hypothesis on it. The results of our experiments reveal that relationship forming is the most dominant online grooming stage in contrast to the sexual stage. We use a widely used word-counting program (LIWC) to create psycho-linguistic profiles for each of the six online grooming stages to discover interesting textual patterns useful to improve our understanding of the online pedophile phenomenon. Furthermore, we present empirical results that throw light on various aspects of a pedophile conversation such as probability of state transitions from one stage to another, distribution of a pedophile chat conversation across various online grooming stages and correlations between pre-defined word categories and online grooming stages

Evolution of Human-like Social Grooming Strategies regarding Richness and Group Size

Human beings tend to cooperate with close friends, therefore they have to construct strong social relationships to recieve cooperation from others. Therefore they should have acquired their strategies of social relationship construction through an evolutionary process. The behavior of social relationship construction is know as "social grooming." In this paper, we show that there are four classes including a human-like strategy in evolutionary dynamics of social grooming strategies based on an evolutionary game simulation. Social relationship strengths (as measured by frequency of social grooming) often show a much skewed distribution (a power law distribution). It may be due to time costs constraints on social grooming, because the costs are too large to ignore for having many strong social relationships. Evolution of humans' strategies of construction of social relationships may explain the origin of human intelligence based on a social brain hypothesis. We constructed an individual-based model to explore the evolutionary dynamics of social grooming strategies. The model is based on behavior to win over others by strengthening social relationships with cooperators. The results of evolutionary simulations show the four classes of evolutionary dynamics. The results depend on total resources and the ratio of each cooperator's resource to the number of cooperators. One of the four classes is similar to a human strategy, i.e. the strategies based on the Yule--Simon process of power law.Comment: 21 pages, 10 figure

Two Types of Social Grooming Methods depending on the Trade-off between the Number and Strength of Social Relationships

Humans use various social bonding methods known as social grooming, e.g. face to face communication, greetings, phone, and social networking sites (SNS). SNS have drastically decreased time and distance constraints of social grooming. In this paper, I show that two types of social grooming (elaborate social grooming and lightweight social grooming) were discovered in a model constructed by thirteen communication data-sets including face to face, SNS, and Chacma baboons. The separation of social grooming methods is caused by a difference in the trade-off between the number and strength of social relationships. The trade-off of elaborate social grooming is weaker than the trade-off of lightweight social grooming. On the other hand, the time and effort of elaborate methods are higher than lightweight methods. Additionally, my model connects social grooming behaviour and social relationship forms with these trade-offs. By analyzing the model, I show that individuals tend to use elaborate social grooming to reinforce a few close relationships (e.g. face to face and Chacma baboons). In contrast, people tend to use lightweight social grooming to maintain many weak relationships (e.g. SNS). Humans with lightweight methods who live in significantly complex societies use various social grooming to effectively construct social relationships.Comment: Accepted by Royal Society Open Scienc

The grooming process in sport: Case studies of sexual harassment and abuse

Drawing on interviews with two elite female athletes from different sports, one from a study in Norway and the other from a study in England, this article explores the process of 'grooming' in the context of sport. Both athletes experienced grooming for sex by their male coaches yet were able to stop the process at a particular point. Grooming has been used to demarcate 'sexual harassment' and 'sexual abuse' as separate points on a continuum of sexually exploitative behaviours. Grooming involves slowly gaining trust before systematically breaking down interpersonal barriers. Elite athletes can become trapped into compliance because they trust and like, or even love, their abusers. The motivation behind sexual harassment and abuse is often power, whereby the harasser seeks to take control over another individual. The abusers use threats (such as being cut from the team) and rewards or privileges to secure co-operation and manipulate the victims to maintain secrecy. Our primary purpose here is to use these adapted realist tales to provide a richer and more personal illustration of these events (within-case) than is presented through extrapolated checklists of 'risk factors' (cross-case). The stories also illustrate vividly elements from the different stages in the grooming process in sport, as described in previous literature. Finally, they reinforce the need to identify protective factors as part of anti-harassment and abuse prevention programmes with both coaches and athletes

A ‘Grooming Chamber’ For Antisemitism

If Jewish Bolsheviks could put an end to the imperial rule of the Romanovs, could they pose a threat to the vision of a Third Reigh? A question the German National Socialists are likely to have asked themselves before and on the eve of plotting the rise of the Nazi regime. After all, Europe had had a long-standing relationship with blaming the Jews for the world’s miseries. A relationship Germany was ready to refuel, as indicated by German Field Marshal Walter von Reichenau, when he stated that ‘the most essential aim of war against the Jewish-bolshevistic system is a complete destruction of their means of power and the elimination of Asiatic influence from the European culture.’ But the German fears of Jewish interference with their great scheme for Europe’s future, must surely have been inspired by more than just the age-old conspiratorial allegation that Jews were the main forces behind world politics. As such, this essay will seek to inspect the apparent rise of antisemitic fears at the time, and put a case forward to show how religion played into all this

The pivotal role of rank in grooming and support behaviour in a captive group of bonobos (Pan paniscus)

We investigated dyadic grooming relationships in a captive group of bonobos (Pan paniscus) and questioned what social function grooming fulfils in the market of services and favors. Hereto we examined which of two theoretical models - grooming for support (Seyfarth, 1977, 1980) or grooming according to the similarity principle (de Waal & Luttrell, 1986) - best accounted for the observed grooming distribution. Similarity in traits did not correlate with increased grooming or close proximity among the individuals. Therefore, the similarity hypothesis was rejected. Seyfarths model of rank-related grooming was largely confirmed. The animals distributed their grooming according to the rank of the receivers. We found an exchange between grooming and receipt of support. There was more grooming up than down the hierarchy. However, not all predictions about rank-related competition over grooming were confirmed. We found that dyadic grooming reciprocity indeed increased with decreasing rank distance. Yet, there was no increase of grooming within the dyad with decreasing rank distance and high ranking individuals were not competed over at the highest rates. The observed correlation between grooming and support received represents an important fit with Seyfarths prediction, but does not allow for conclusions about underlying causal processes. Other causal explanations, besides the groom to receive support hypothesis, that could explain a similar correlation are discussed
