Post-Purchase Rationalization

Post-purchase rationalization is the tendency to convince oneself, after a purchase or decision, that it was a good choice, typically by emphasizing the option's positive qualities and minimizing or overlooking its flaws. It is treated as a specific consumer-behavior expression of cognitive dissonance: doubt about the cost or drawbacks of a purchase creates psychological discomfort, which the buyer reduces by revising their own judgment of the product upward rather than admitting a possible mistake. The effect is most pronounced after costly, effortful, or hard-to-reverse purchases, where the discomfort of a wrong decision would be greatest.
