Bike shed effect

We tend to spend more time on figuring out trivial things rather than spending time on the important things.

Example

A committee whose task is to create plans for a nuclear power plant might spend a disproportionate amount of time on deciding materials to use in the bike shed of the plant(hence, the name of the effect)

Cause

People might be less inclined to comment on complex parts(like a nuclear plant) - but are confident to comment on simpler things(bike shed).
