The "80/20 rule cheating" theory suggests people cheat to find the "missing 20%" of needs not met by their primary partner (who provides the "80%"), often chasing temporary excitement while risking the stable relationship they already have. It's a justification where individuals focus on unmet desires (like physical attraction or specific validation) in someone new, ignoring the substantial good their primary partner offers, which can lead to losing the valuable 80% for a fleeting 20%. While often linked to infidelity, the core idea (from the Pareto Principle) is about focusing efforts, but in relationships, it's misused as an excuse for seeking perfection or avoiding work in a healthy, but imperfect, union.
