Genetic Predisposition and Infidelity: From Molecular Variation to Relationship Behavior-A Narrative Review.
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Trust and pair bonding are central to human social life, and their violation through infidelity carries a measurable psychological cost. Whether individual differences in such behavior are partly genetic remains contested, because the available evidence combines heterogeneous phenotypes with candidate gene designs of limited statistical power. This narrative review synthesizes genetic evidence on infidelity, pair bonding, responses to trust violation and indirect traits such as novelty seeking, grading it by evidentiary strength. Twin modeling of extrapair mating yields broad-sense heritability of approximately 62% in men and 40% in women, but this specific estimate has not been reproduced in a comparable sample and describes population variance, not individual causation.
