Negatives are easier to identify than positives. Building up is much harder than tearing down. Finding the bad is far easier than pointing out the good. Criticism flows much easier from the tongue than praise.
Pointing out what's wrong is not rocket science. Solution crafting is our real work, and that requires optimism, engagement, creativity, buy-in, and teamwork, none of which are the fruits of wrongfinding.
Viewing the world and engaging others from a deficit mindset changes little and wins few converts.
The best leaders I know follow the road less taken; they choose to find and accentuate the stuff that's going right disproportionately over the stuff that's going wrong. And yes, it is a choice.
Wrongfinding is a fool's errand.
