It is much easier to be critical than to be correct.

Finding the flaw in something takes a fraction of the effort that making it did. Criticism can be produced quickly, sounds intelligent, and carries no risk, since you are never on the hook for a proposal of your own. Being right is slower and exposes you. The distinction matters because a room full of critics can feel rigorous while nothing is actually being tested.

When you next object to something, attach what you would do instead. If you cannot produce an alternative, say the objection more tentatively, because you are further from an answer than the confident tone suggests.
