Evolutionary psychologists found evidence more than three decades ago for sex differences in jealousy towards infidelity (Burchell, & Ward, 2011). An abundance of studies have been conducted to increase our understanding of these sex differences, and a multitude of theories have been created to explain them (Levy, Kelly, & Jack, 2006; Sagarin & Guadagno, 2004; Tagler & Gentry, 2011; Walum et al., 2013).

It is widely believed that men and women respond differently to infidelity in the way they think and act (Buss, Larsen, Westen & Semmelroth, 1992; Takahashi et al., 2006; Walum et al., 2013). Past research has found that women tend to report more It states that due to female fertilisation, males are threatened by a reduction in reproductive success and females are threatened by resource withdrawal (Levy, Kelly, & Jack, 2006; Walum et al., 2013). Binary-choice measures use simultaneous presentation which can alter how well a person is able to approximate each scenario.
