Paradox**:** The buyer cannot inspect the product without purchasing it, but without inspecting it, the buyer is unwilling to purchase.

To solve this paradox, many entrepreneurs have chosen the "try before you buy" model. For example, free trials, unconditional refunds, or conditional refunds. These models allow the buyer to use the product or service first and then decide whether to make a purchase. A trial allows the buyer to test the product or service without assuming any risks; an unconditional refund gives the buyer the right to return the product at any time after purchase without worrying about getting their money back; a conditional refund provides guarantees on certain metrics and performance of the product or service. This model effectively solves the problem of buyers being hesitant to purchase while also ensuring the company's reputation and the quality of the product or service.

The "try before you buy" model gives users the power to evaluate the product, but most products rely on the user's own morals to provide honest feedback. If users lack moral integrity, in a completely selfish and anonymous one-time game, they have no incentive to provide honest feedback. Instead, they will likely give the worst rating to trigger the refund mechanism and get the product for free.

To solve the issue of impure motives in the game, the P.I.V.O.T. protocol alters the game environment by decoupling the usage, evaluation, and payment of the product, ensuring that the user's optimal decision is always equal to providing an honest evaluation.
