I think this is called bikeshedding.

[Normal_gaussian]

Bikeshedding is from Parkinson's law of triviality [1], which essentially says that deciding trivial issues takes a disproportionate amount of time - partly because there are many ways it could be done, and partly because non-trivial issues are hard to comprehend and are therefore easy to agree with.

This differs from the OP, where it is the ability to control an issue that is to blame - in Parkinson's law control is equal yet understanding is not.

Though of course the relation is strong.

Not really that close. Bikeshedding is putting focus on something that doesn't matter, but is easy to argue about.

This is taking something that really does matter, but it's too late to change most of it, and putting too much effort into the remainder.
