We provide a first systematic investigation of the most prominent hypotheses about the impact of mate value on interpersonal attraction in real-life early-stage romantic encounters.Using Response Surface Analysis, we simultaneously examined how (a) people's perception of their own mate value, (b) their perception of a potential partner's mate value, and (c) the interplay between the two mate values impact initial romantic attraction and selection as well as subsequent interpersonal outcomes after selection. Data came from the "Date me forScience" speed-dating study (n = 398), in which participants who mutually selected each other at the speed-dating event were followed up with 3 assessments in the 6 weeks after the event to assess subsequent outcomes. Participants' romantic attraction, likelihood of selecting, and subsequent interpersonal outcomes with a dating partner almost exclusively depended on their perception of their dating partner's mate value: the higher, the better. There was no evidence for the popular matching hypothesis, which states that people feel attracted to and select dating partners whom they perceive to have a mate value similar to their own.Implications of these findings for theory and research on the impact of mate value on romantic attraction and selection are discussed.

One of the most crucial questions about mate value is how it influences romantic attraction and partner choice. Two competing theoretical assumptions about this influence dominate the field: the idea that individuals feel attracted to and select potential partners who are similar to themselves in mate value versus the idea that individuals feel attracted to and select potential partners with a high mate value (e.g., Olderbak, Malter, Wolf, Jones, & Figueredo, 2017;Penke et al., 2008; Taylor, Fiore, Mendelsohn, & Cheshire, 2011; Van Straaten, Engels, Finkenauer, & Holland, 2009; see also Ellis & Kelley, 1999). Prior empirical examinations of these hypotheses have predominantly focused on specific aspects of mate value (especially physical attractiveness; e.g., Berscheid, Dion, Walster, & Walster, 1971; Curran & Lippold, 1975;Montoya, 2008; Van Straaten et al., 2009; Walster, Aronson, Abrahams, & Rottman, 1966), but only a few studies so far have investigated global mate value-and these few studies revealed mixed evidence regarding the two hypo...
