I'm not sure I get it, how is a paranoid one just as good?LOL
What Demon said: you can't possibly know you're paranoid at least until day 2 and wtf...! Two guilty results could mean your insane xDDD which is as good as a sane one, not useless. I still don't see how it would be selfish anyway even after you explained it o.o it's not like a paranoid detective can benefit solely his own self in any case @.@ he can't do anything
