is there such thing?
"belief" is something you cannot prove. ever. as soon as you can prove it, it's no longer belief, but knowledge. science so to speak.
as long as you believe somthing you cannot prove, it most probably is a genuine belief. one doesn't believe in something he/she doesn't believe in. thus, i'll make the point that there is no such thing as "false belief". there are only "true believes". as long as you don't have knowledge, that is.
