Choice Overload.
If
The time to make a decision grows logarithmically with the number of choices: T = b·log₂(n+1). More options do not just add visual clutter — they measurably slow every user down.

Cut the number of choices on any screen or API surface to the few that matter; push the rest behind defaults and progressive disclosure. Fewer doors, faster decisions.
Unless
Progressive Disclosure / Sensible Defaults
