The chains of wedlock are so heavy that it takes two to carry them; sometimes three.

Jealousy has often been considered a dangerous emotion because it motivates a wide range of behavior including spousal violence and abuse. It is therefore a major task of jealousy research to identify potential determinants of jealousy-motivated behavior. One such potential determinant is the intensity of the jealousy feeling. It appears reasonable to assume that mild jealousy feelings promote rather innocuous mate retention tactics such as heightened vigilance. In contrast, very intense feelings are more likely to evoke ferocious reactions including violence and abuse.

Several determinants of jealousy intensity have been identified. First, sneaking suspicions of a partner’s infidelity appear to result in mild, anxious-insecurity like jealousy feelings, whereas the certainty of actual infidelity is associated with intense, rage-like jealousy feelings.

Secondly, based on evolutionary psychological considerations, Buunk and his colleagues provided substantial empirical evidence that rival characteristics affect jealousy intensity. These authors found that a (potential) rival’s high physical attractiveness elicits more jealousy in women than in men. In contrast, a (potential) rival high in social and physical dominance and social status evokes more jealousy in men than in women.

Third, a fundamental factor contributing to the intensity of jealousy concerns the infidelity type the partner engages in. Empirical evidence continues to accumulate confirming the evolutionary psychological hypothesis that men respond with more intense jealousy than women to a mate’s sexual infidelity whereas, conversely, women respond with more intense jealousy than men to a mate’s emotional infidelity.

As the unfaithful partner most likely tries to conceal his or her infidelity, the jealousy mechanism often needs to rely on indirect evidence from which a mate’s infidelity can be inferred. An important source of such indirect evidence consists of sudden and conspicuous changes in the partner’s behavior. (…) However, the sudden and conspicuous changes in the partner’s behavior as factors contributing to jealousy intensity and thus determinants of jealousy-motivated behavior have several limitations. First, these behavioral changes are often ambiguous with respect to the infidelity type (e.g., the clothing style suddenly changes; he or she stops returning your phone calls), thus presumably requiring complex inference processes that are prone to errors. Second, some if not most of these behavioral cues to infidelity were certainly not available during our ancestors’ past, (e.g., the clothing style suddenly changes; he or she stops returning your phone calls). As a consequence, they could not have shaped the jealousy mechanism during its evolutionary history. (…)

These considerations raise the question whether there are possible additional cues to infidelity that do not suffer from the limitations mentioned above. The present study picks up this question and examines a hitherto neglected but fundamental proximate contextual factor in jealousy research: The spatial distance between the persons involved in the “eternal triangle” (Buss, 2000), that is the partner, the potential rival and the jealous person. Spatial distance between the three persons (a) was recurrently available to our ancestors and thus could have been exploited by the jealousy mechanism throughout our evolutionary past, (b) can be clearly detected, (c) is not ambiguous and thus does not require complex inferential processes, (d) informs rather directly about appropriate mate guarding behavior (e.g., moving closer to the partner; increasing the distance between the partner and the potential rival or stepping between the partner and the potential rival).
