“Involuntary Singlehood and Its Causes: The Effects of Flirting Capacity, Mating Effort, Choosiness and Capacity to Perceive Signals of Interest”, Menelaos Apostolou2021-07 (; similar)⁠:

A considerable proportion of the population is involuntarily single; that is, they want to be in an intimate relationship but they face difficulties in doing so. The current paper attempted to assess some possible predictors of this phenomenon.

More specifically, in a sample of 1228 Greek-speaking women and men, we found that participants who scored low in flirting capacity, capacity to perceive signals of interest and mating effort, were more likely to be involuntarily single than in an intimate relationship, and experienced longer spells of singlehood. Mating effort had also a statistically-significant effect on voluntary singlehood, with low scorers being more likely to be in this category than high scorers. Choosiness had also a statistically-significant effect, but only on voluntary singlehood, with high scorers being more likely to prefer to be single than low scorers.
