“New research is putting age-gap relationships back in the spotlight after findings showed both men and women rated younger dates as slightly more desirable after first meetings. Another study found women who were more than 10 years older than their male partners reported higher relationship satisfaction and commitment than women dating…”
Plain restatementTwo research claims are made:
Both research claims in this post are real. The "younger dates rated as slightly more desirable" finding comes from a 2025 peer-reviewed PNAS study by Eastwick and colleagues, which analyzed roughly 4,500 blind dates among middle-aged adults and found a small preference (about 55%) for younger partners with no meaningful gender difference. The "women more than 10 years older reported higher satisfaction and commitment" claim comes from a 2023 Psychology Today blog post by Justin Lehmiller reporting on his own survey of about 200 heterosexual women, which is a much smaller and less rigorous evidence base than the first study. The post treats the two findings as equally weighty, which they are not. The final line about modern dating moving away from old rules is opinion, not something either study demonstrates.
[drifted from the evidence:] New research [drifted from the evidence:] is putting age-gap relationships back in the spotlight after findings showed both men and women rated younger dates as slightly more desirable after first meetings. Another study found women who were more than 10 years older than their male partners reported higher relationship satisfaction and commitment than women dating men closer to their age or older.

Red-tinted words in the claim drifted from the evidence. Green-tinted words are what a neutral restatement needs.
The trace / claim to source
- A real, peer-reviewed PNAS study (Eastwick et al., 2025) found that both men and women were slightly attracted to younger partners in a blind-date setting, with no gender difference. The word "slightly" in the Instagram claim matches the source's own characterization.
- Lehmiller (2023) did report the "10 years older" satisfaction/commitment finding.
- The described comparison ("closer to their age or older") is broadly consistent with the Lehmiller comparison groups (women younger than partners, and other configurations).
- The Instagram post frames both findings as if they were of equal empirical weight. In reality, the blind-dates finding comes from a large peer-reviewed PNAS study, while the "10+ years older" finding comes from a ~200-person survey reported by the researcher on a Psychology Today blog. This is an omitted qualifier / methodology-mismatch issue.
- The concluding line ("Modern dating is clearly moving away from the old rules") is editorial extrapolation not supported by either study. Neither paper makes a claim about generational trends in dating norms.
- The Eastwick study's effect was small (about 55% preference), and the sample was specifically middle-aged adults seeking long-term partners. Generalizing to "modern dating" broadly is a temporal/population overreach.
- The exact wording of the Lehmiller survey items (satisfaction and commitment scales) is not visible in the blog-level source; the underlying data has not been located in a peer-reviewed journal article as of this investigation.
- Whether the Lehmiller finding replicates in larger, peer-reviewed samples remains unclear; some related studies find mixed or opposite patterns for age-gap satisfaction.
Claim 1 (blind dates / younger preferred): A 2025 PNAS study by Eastwick and colleagues analyzed a set of blind dates among middle-aged adults seeking long-term partners. The sample was a set of N = 6,262 middle-aged adults who signed up for a blind date service, and preregistered tests revealed that people were (slightly) attracted to younger partners on average, and this association did not differ by gender. Coverage of the study describes the effect as small but consistent: both men and women were slightly more likely to rate younger partners as desirable, with daters choosing the younger of two potential partners about 55% of the time. The study specifically examined attraction in a blind-date context, not stated preferences. Claim 2 (women 10+ years older report higher satisfaction): Reported in a March 2023 Psychology Today blog post by Justin Lehmiller. Lehmiller reported that women who were more than 10 years older than their male partners were the most satisfied with and committed to their relationships compared with both women who were younger than their partners, as well as women in other age configurations. Lehmiller proposed a mechanism: when a woman is older than her male partner, this may shift power dynamics toward greater equality, and older women may feel more empowered to get what they want in their relationships, sexually and otherwise. Sample size context: in Lehmiller's survey of roughly 200 heterosexual women, those more than 10 years older than their male partners were, on average, thriving.
