I ran into indirect realism quite a while ago, I think in neurophysiology or ethology to begin with. (A percept relating to an object is not the object itself).

Not sure why you bring up that and CWA here at this time though. Does it have something to do with falsifiability from your perspective? I think falsifiability is more of an OWA kind of thing though, isn't it? (The idea being that you never have sufficient information to know if something is true, only if it is positively false. That sounds pretty OWA to me, right?)

I'm interested to hear what you mean by "and the consequences" , because I truly have no idea what you might be seeing, and I'm really curious now. I get the impression you see people making certain kinds of mistakes?
