Which metrics were used to assess mating success in the studies?

• A. Number of sex partners
• B. Age of first intercourse
• C. Sociosexuality
• D. All of the above

Answer: (D)

Mating success is best understood as a multi-faceted outcome, so researchers assess it using several indicators that capture different aspects of mating opportunities and strategies. The number of sex partners reflects realized mating events and the extent of actual mating opportunities someone has had. The age of first intercourse signals mating onset and timing, which can influence reproductive opportunities and strategic sexual behavior over a lifetime. Sociosexuality measures attitudes and behaviors related to pursuing uncommitted or casual sex, tapping into mating strategies and willingness to pursue multiple partners even in the absence of long-term commitment.

Using all three together provides a fuller picture: actual mating success through partner count, the timing of initiating sexual activity, and the individual’s orientation toward casual mating. While each metric has limitations on its own, their combination yields a more comprehensive assessment of mating success.
