The paradox of choice is a phenomena where having more options can cause us to delay making a decision or give up on making one altogether. We may overthink the decision, as is in the case of analysis paralysis (https://lib.hol.ink/index.php?topic=47). We may experience high cognitive load (https://lib.hol.ink/index.php?topic=31.0) trying to parse too many individual options in a short period of time.
As humans, we tend to seek out as many options as possible, and we often delay making a decision because we think we don't have enough options to pick from. Yet once we do have many more options in front of us, that disrupts the human brain in a different way, and we once again delay the decision. Hence the "paradox." We crave a wide selection that we cannot actually use.
There are various ways we can reduce the effects of this paradox as it's experienced by artists, such as the use of creative constraints (https://lib.hol.ink/index.php?topic=48) and design palettes.
But it's important to remember that our viewers, listeners, players, etc. will also be affected by this paradox. This is why sales people and marketers have things like funnels with only one or two calls-to-action. This is why apps have opinionated layouts and methodologies for accomplishing tasks in their systems. This is why many artists only offer prints in a couple sizes, even when they're using a print-on-demand platform that allows hundreds.
The more options you give people, the less likely they are to ever make a decision.
