It is the convergence of <em>genetic reward architecture — the DRD4 7R+ allele and MAO-A novelty-seeking variant that elevate the dopamine threshold required for satisfaction</em> — 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.</p>
