From the perspective of professional security circles, school 1 applies, ātarget hardeningā I believe they call it.There are two schools of thought.
1 - Open carry provides a deterrent; a bad guy is likely to go elsewhere looking for unarmed victims.
2 - open carry is a sign that says "shoot me first".
There's not actually any evidence at all to support either position, so go with your gut. I lean slightly towards the "shoot me first" sign, and also feel like open carry is attention seeking behaviour. So I conceal.
From the perspective of single carriers, who want to be left alone and move about, school 2 applies.
Niether is wrong, just used differently.
