What explains the wide variation in reported cheating rates in meta-analyses?

• A. Differences in culture
• B. Differences in sample size
• C. Differences in age
• D. Differences in definitions

Answer: (D)

The main thing that explains wide variation in reported cheating rates across meta-analyses is differences in how cheating is defined and measured. Some studies count only sexual infidelity, others include emotional or financial breaches, and still others use varying timeframes (lifetime, past year, past month) or different relationship contexts. When one study counts a broad set of behaviors as cheating and another uses a narrow definition, their reported rates can look very different even if they’re studying similar populations. How cheating is assessed also matters—self-reports vs. partner reports, anonymous surveys vs. face-to-face interviews—which affects what people are willing to admit. While culture, age, and sample size can influence prevalence, the biggest driver of inconsistency across meta-analyses is the lack of a standardized, consistent definition and measurement approach. Researchers address this by examining heterogeneity and, when possible, keeping definitions aligned or analyzing by definitional subgroups to make comparisons more meaningful.
