The Excel sheet is divided into 3 tabs, reflecting the three different waves of Singles in America used in this work and all raw variables needed to draw identical results described in our paper. This dataset does not include transformations (e.g. Stress remains in categorical, not numeric, form). Singles in America is sponsored by the online dating company Match.com; however, participants were not drawn from the Match.com or subsidiary site populations. Additional details on how each sample was collected are available in the manuscript. This dataset contains only a subset of the original Singles in America dataset, both in terms of individuals included and variables measured. The original data in Study 1 and 2A limited participation to US residents age 21+ identifying their sex as male and female. Further, those individuals were only included if they were not married, engaged, in a domestic partnership, or living together. The sample provided here is further limited to heterosexuals who were not currently dating someone and also excludes those not providing their marital status. Study 2B recruited individuals as young as 18 who were single in the legal sense (i.e. being unmarried). The sample shown here includes only heterosexuals identifying as male or female who were not in a commited dating relationship and were either single and not seeing anyone or casually dating one or more people. Data Provided (Varying by Study): Age: In Years Sex: Male or Female Sexual-Timing Strategy: "How long do you typically wait before having sex with a new partner?". Blanks in Study 2B reflect individuals who preferred not to answer or did not give a response. Sexual Thoughts Frequency: How often participants thought about sex. Sexual Activity Frequency: How often participants had sex in the past 12 months. Stress Over Biological Clock: Stress produced by ticking of biological clock on a 5-point Likert-type scale. Comments on Single Status A Month: 0-19, with individuals replying '20+' having their response removed.

Data contains personnal and ascoustics information on every participant in the study. Corrigendum: This dataset has been updated (update on 26.07.2019). A few errors were reported in the previous one, so use this one instead if you want to re-run the analyses. Also note that the individuals marked as MD_17012017_14 and MD_08022017_56 were not used in the analyses, and this was unfortunately not mentioned in the article. Those individuals were removed as they presented an unusually high number of mating partners. However, adding or removing these two individuals from the analyses did not change qualitatively the results.

Data supporting meta-analysis and systematic review of the 'Watching Eyes' effect on anti-social behaviour, accepted for publication in Evolution & Human Behaviour. The paper systematically reviews the eye cue literature noting failed replication attempts, and two meta-analyses which raise doubts about the reproducibility of the watching eyes effect on generosity. However, it also highlights that much of the wider evidence on eye cues has still not been systematically reviewed, notably that which is most relevant to its practical application: the effect of eye cues on antisocial behaviour. Given the evidence of humans' heightened sensitivity to threat and negative information, it is hypothesized that the watching eyes effect would be more consistent on antisocial behaviour. In a meta-analysis of 15 experiments from 13 research papers we find a reduction in the risk of antisocial behaviour of 35% when eye cues are present. By contrast, reviews suggest that CCTV cameras reduce crime by only 16%. Our meta-analytic evidence for a watching eyes effect on antisocial behaviour is sufficient to justify the use of eye cues in the very low-cost and potentially high-impact real-world interventions that are proliferating in public policy, particularly in the UK.
