Sure but, while stupid move can be supposed easier to perform by average individual, you can combine both malice and stupidity, and not all regrettable situations are indeed adequately explained by stupidity alone, or even with any stupidity involved at all.

Plus, supposing those at source of disliked outcomes are cleaver than they look can certainly help better preparing counteractions. Just stating "people that did this or that are stupid" might give some immediate feel good feedback with like-minded, but it doesn’t sharp the mind toward relevant plan to improve the situation (according to self and its clique)
