Picture yourself walking into a car dealership. Two salespeople are free and ready to help. One is strikingly good-looking. The other is pleasant but ordinary. Which one do you walk toward?
Decades of marketing research would bet on the attractive one. But a set of studies published in Psychology & Marketing offers evidence that the answer depends on something the salesperson can’t see: whether the shopper is in a committed romantic relationship. And the pattern shows up for one group in particular.
The pull of a pretty face
Researchers have long documented what psychologists call the “beauty-is-good” stereotype. People tend to assume that attractive individuals are also more competent, more trustworthy, and more capable. Attractive people are more likely to be hired, promoted, and paid well, and are even less likely to be convicted of crimes.
That bias carries into stores and showrooms. Consumers tend to rate attractive salespeople as more likable, better communicators, and more expert. Studies have linked salesperson attractiveness to higher customer satisfaction, stronger purchase intentions, and better sales numbers. The takeaway for managers has been simple: good looks help.
Veronica L. Thomas of Old Dominion University, along with Stephanie M. Mangus of Baylor University and Dora E. Bock of Auburn University, wanted to test whether that story is complete. The authors argue that the benefits of attractiveness may have limits, and that one of those limits comes from an unexpected place: a shopper’s love life.
Borrowing an idea from relationship psychology
The team drew on research about how people in committed relationships protect those relationships. That body of work finds that partnered individuals often guard against temptation by paying less attention to attractive alternatives. In experiments, people in relationships spend less time looking at photos of attractive potential partners, and some studies of brain activity suggest they mentally lean away from such images.
The researchers reasoned that a sales encounter is a spot where this instinct might surface. Unlike a passing glance at a stranger, choosing a salesperson often means committing to an extended, one-on-one interaction. If an attractive salesperson registers as a possible romantic threat, the authors proposed, a committed shopper might quietly avoid that person and gravitate toward someone less attractive instead.
They laid out two predictions. First, as a consumer’s relationship commitment rises, the consumer becomes more likely to approach a less attractive salesperson rather than a more attractive one. Second, this avoidance happens specifically because the attractive salesperson is perceived as a relationship threat, not because of general discomfort.
Testing the idea across several studies
To keep the salespeople relevant as potential romantic partners, the team ran separate versions of each study for heterosexual women and heterosexual men. Women saw photos of male salespeople; men saw photos of female salespeople. Before the studies, the researchers pretested a pool of images to identify one “attractive” and one “moderately attractive” salesperson of each gender, confirming through participant ratings that the images differed reliably in attractiveness but not in perceived warmth or competence.
In the first pair of studies, 108 women and 100 men recruited through the survey platform Prolific were asked to imagine visiting a car dealership to negotiate a purchase. They then chose which of two salespeople they preferred to work with, and afterward reported how committed they were in their romantic relationship on a seven-point scale.
Among women, the pattern held: as relationship commitment increased, participants were less likely to pick the attractive male salesperson. Among men, relationship commitment made no difference in whom they chose.
The researchers then checked whether that gender gap might be a fluke of a small sample. A second pair of studies, using 149 women and 187 men from a university subject pool, swapped the negotiation setting for a “no-negotiation” dealership where the sticker price was final. This ruled out the possibility that the effect depended on the stress of haggling. The results repeated. More committed women leaned away from the attractive salesperson, while men’s choices were unaffected by their commitment level.
Zeroing in on the “why”
The final study, with 613 participants, was built to test whether relationship protection was really the driver. This time, everyone chose from four salespeople at once: an attractive man, a moderately attractive man, an attractive woman, and a moderately attractive woman.
The logic was to separate two possible explanations. If committed shoppers simply feel uneasy around anyone of the opposite sex, they would avoid all opposite-sex salespeople. But if the concern is specifically about temptation, they would avoid only the attractive opposite-sex option, since that person poses the actual threat.
The results matched the second explanation for women. As relationship commitment rose, women grew less likely to choose the attractive male salesperson compared with any of the other three options. Their commitment level did not push them away from the moderately attractive man, even though he was also of the opposite sex. In the authors’ reading, this suggests that attractiveness itself, not just the salesperson’s gender, is what triggers the avoidance. For men, commitment again had no significant effect on their choice.
The team also checked whether other factors might explain the results. Across follow-up tests, they found the effect was not accounted for by self-presentation concerns, self-esteem, perceptions of the salesperson’s power or warmth or competence, or men’s confidence in negotiating. In one test, men reported similar negotiation confidence regardless of whether the salesperson was male or female, attractive or not.
Why women and not men?
The gender difference was not something the researchers set out to find, and they are cautious about it. They point to prior relationship research suggesting that women, regardless of their relationship status, tend to look at attractive alternatives for shorter periods than men do, and that the strategies people use to guard their relationships can differ by gender. The authors treat the finding as a starting point for further study rather than a settled conclusion.
What it might mean for businesses
For managers, the study complicates the assumption that stocking a sales floor with attractive staff is always a winning move. The authors suggest that in settings where customers choose whom to approach, such as car lots, cosmetics counters, gyms, or real estate and financial services with online agent profiles, some committed shoppers may steer away from the most attractive representative.
They offer a few possibilities for firms to consider. Building sales teams with a mix of representatives gives customers a sense of choice. Marketing materials and online profiles can emphasize a salesperson’s skill, warmth, and credibility rather than looks. And where a customer can’t pick a salesperson, training staff to keep interactions professional and task-focused might reduce any sense of personal threat.
A few caveats are worth keeping in mind. The studies were conducted with heterosexual participants choosing opposite-sex salespeople, and they relied on convenience samples of online survey takers and college students, which may limit how far the findings generalize. Participants also reacted to photographs in imagined scenarios rather than live salespeople in real stores. And because relationship commitment was measured, not assigned, the research shows an association rather than proof that commitment causes the avoidance.
Still, the pattern points in a consistent direction across five samples. As the authors put it, “beauty is not always better.”
