Serial Cheating and the Brain: Why Genetic Reward Architecture Drives Repeat Infidelity The serial cheating brain is not a moral defect or generic willpower failure. It is the convergence of genetic reward architecture — the DRD4 7R+ allele and MAO-A novelty-seeking variant that elevate the dopamine threshold required for satisfaction — with mesolimbic pathway tolerance produced by repeated novel-partner stimulation. Each successive novel encounter produces a smaller dopaminergic response than the one before. The behavior escalates rather than resolves because the reward threshold keeps rising. ...
