Reciprocity of liking
On average, people who think someone likes them report a little more interest in that person, and tend to underestimate how much they were liked.
Evidence: Supported with caveatsSupported with caveats: Several studies agree, with stated limits such as student samples or lab settings. This is the weakest level among the claims below.
What the research shows
Several studies find that people who believe a particular person likes them tend to report somewhat more interest in that person. The link is small (in the one speed-dating report, a correlation of about .14), the reciprocity is only partial, and the studies are correlational, so they cannot show that being liked causes liking. A separate line of studies finds that after a first conversation people tend to underestimate how much their partner liked them, in lab strangers, new dorm mates and workshop attendees. What you can take from it: nothing here suggests hiding honest interest, and a flat feeling after a conversation is not, by itself, evidence that it went badly.12
What dating marketing says it shows
A typical sales line, written for this page
A typical sales line promises: "Give her something first, and she will feel she owes you her attention." Pages like this present reciprocity as a debt you can create in someone, so that liking becomes something owed.
What doesn't follow
The studies describe a modest average link between feeling liked and liking back; they do not show that any act creates an obligation to like you, and they cannot tell you whether a particular person does.
Limits
Speed-dating events with 156 undergraduates, a seven-month study of singles, and lab, dorm and workshop conversations. Self-report and correlational designs; the reciprocity link is small. The liking gap comes mainly from one research programme and measures general liking, not romantic interest. Population averages: none of it says whether one person likes you.

Evidence: Supported with caveatsPeople who perceive that a particular person likes them tend to report somewhat more interest in that person, although the speed-dating evidence for this is limited and the studies cannot show which comes first.
Why this label
Several studies agree, with stated limits such as student samples or lab settings. In speed-dating, desire that was unique to a pair showed some reciprocity, and in a seven-month study of singles, perceiving that a potential partner was interested was one of the robust positive predictors of one's own interest.
What it does not show
- The speed-dating report is a short report with 156 undergraduates; its full text was read in the S7.1 check, which confirmed the pattern; the reciprocity correlation it reports is small (r = .14). The r = -.41 in the same report belongs to a different finding, that desiring many people predicted being desired less (c3).
- All three sources are correlational: perceived interest and one's own interest are measured by self-report at the same time, so they do not show that being liked causes liking in return.
- Luo and Zhang describe only 'some support' for reciprocity, so the effect is not uniform across samples.
- These are population averages; they do not tell you whether a given person likes you.
- The Luo and Eastwick 2022 abstracts support only 'some' reciprocity and perceived interest as a predictor.
Who it applies to
A pattern across groups of people, not a statement about any one person.

Evidence: Supported with caveatsAfter a first conversation, people tend to underestimate how much their partner liked them.
Why this label
Several studies agree, with stated limits such as student samples or lab settings. The 'liking gap' appeared in several settings: strangers in a lab, first-year dorm mates, and members of the public at a workshop. It lasted across conversation lengths and for months in new dorm relationships. Being liked more than you think is a common situation, not a sign of rejection.
What it does not show
- Samples were lab strangers, college students and workshop attendees, not dating contexts; it measures general liking, not romantic interest.
- Reported mainly from one research programme; independent replication was not checked here.
- A population-level tendency: it does not mean a particular partner is secretly interested.
Who it applies to
A pattern across groups of people, not a statement about any one person.
