Who loves whom? The relationship between love and workload

A previous study (Iha, 2024a) found that men and women who loved their hypothetical opposite-sex partner voluntarily made more costly choice than men and women who were loved by their hypothetical opposite-sex partner. However, it is unknown whether the same effect occurs even when explicit costs are not included. The purpose of the current study was to replicate and extend the results of the previous study. Participants from four countries (Canada, Germany, the UK, and the USA) were recruited to engage in an online scenario experiment. The results indicate that the replication and extension were successful. In other words, across four countries, men voluntarily undertook more work than women in general, but both men and women voluntarily undertook more work if they loved their hypothetical opposite-sex partner than if the hypothetical opposite-sex partner loved them.
