Offering people more choices that differ along many dimensions, may diminish their satisfaction with their final choice. Losses are more painful than the corresponding gains are pleasurable, so people think of the dimensions along which their final choice was inferior, and of all the other opportunities passed up. If you can only choose one dessert, you're likely to be happier choosing from a menu of two than from a menu of fourteen. Refusing tempting choices consumes mental energy and decreases performance on other cognitive tasks. A video game that contained an always-visible easier route through, would probably be less fun to play even if that easier route were deliberately foregone. You can imagine a Devil who follows someone around, making their life miserable, solely by offering them options which are never actually taken. And what if a worse option is taken due to a predictable mistake? There are many ways to harm people by offering them more choices.
