This may be true in some cases, but I’ve also seen issues with too many stamps, signatures, red-tape, tribunals/committees, and multi-stage approval chains.

There’s a balance somewhere put there, but that balance is different for everyone.

Personally I think problematic decision making is more to do with the “blame” side of ownership. It benefits the unsure more than the certain, and not many people are okay with making and admitting to mistakes.
