Participants were invited via online recruitment on Facebook, with a maximum of 18 participants invited for each session, and took part in several tasks for a set of studies. Each session consisted of either men, or women only. Only self-reported heterosexuals were recruited for the study in order to clearly discern relationships between the measured variables on a sample of the target size. In total, 158 people participated in the experiments (74 men, 84 women, mean age=21, median of age=21).<br>Participants were greeted at the reception and led to the computer lab with seats separated by cardboard screens, so that the subjects could not see each other or otherwise interact during the experiment. They read and signed their informed consent and were able to ask questions about it before the commencement of the experiments. At the beginning of the computer-based survey, participants viewed twenty neutral-expression frontal portrait color photos of people of the opposite sex. The priming part of the session was always overseen by an experimenter of the same sex as the subjects.<br>The subjects were asked to rate the attractiveness of the faces on an 8-point Liekert scale. One half of the subjects was randomly allocated photos rated as less attractive on the same Liekert scale by an independent sample in a previous online questionnaire (Machová 2018), the other half was shown the twenty faces rated as more attractive. The unattractive sample of men was originally rated 2.73 on average, the attractive 3.97 (t=7.98, df=37.67, p&lt;0.0001) on a 8-point scale. In women, the unattractive sample had an average rating of 3.01, the attractive 5.21 (t=9.64, df = 33.05, p&lt;0.0001) on the same scale. Differences of the priming sets in other characteristics are shown in Table S1 in Supplementary Material.<br>Afterwards, the subjects played the Dictator and Ultimatum Games, each for 400 tokens translatable into 40 CZK (approx. 2 USD). They were presented with the rules and truthfully told that they would be randomly matched with another subject in the room and that their earnings at the end of the experiment would reflect the outcome of both games. Each subject was asked how much they want to give and offer the other player, what is their minimum acceptable offer (MAO) in the UG from their co-player and also whether they would hypothetically accept or reject an offer of 120 tokens (30% of the pie). The survey contained control questions to assess whether the participants understood the rules of the games before they played and also a question about previous knowledge of the games (e.g. from university classes, popular science reading etc.).<br>The participants subsequently filled a questionnaire asking about the number of sexual and romantic partners during the past year and during their life so far. Three questions were aimed at one’s own self-perceived attractiveness in terms of both physical appearance and personality. Big Five personality factors (agreeableness, extraversion, openness, neuroticism and conscientiousness) were also measured via Ten-Item Personality Inventory, or TIPI (Gosling et al. 2003), as previous research found a connection of each of them with some aspects of altruism and cooperation and they might modulate the participants’ responses (Clark et al. 2014, Oda et al. 2014).<br>Finally, in order to avoid the possible confounding effects of one’s status, the participants were also asked about their economic and social-family life satisfaction. Other data was collected for related studies on conditions of Triversian reciprocity and hormonal effects, respectively (Novakova et al., in preparation): health, temporal discounting, cognitive reflection, intelligence, memory, risk-taking propensity, facial photograph, 2D:4D and salivary cortisol and testosterone levels. At the end of the testing, subjects were informed about the goals of the experiment and paid their reward.<br>
