The two goals: 1) having true beliefs, 2) not having false beliefs may seem to be equivalent or something like that, but they in fact result in different optimal strats. Not having false beliefs If one has only goal (2), the optimal strat is to believe as few things as possible, suspending belief about most things. Even if one meticulously checks the evidence to avoid being wrong, one will make mistakes once in a while perhaps simply because the current best available evidence about the subject is misleading (i.e. indicates that a particular thing is true that is actually false). So, the optimal strat is to believe nothing at all, but it is hardly possible to live like that. Unfortunately acquiring beliefs is more or less automatic in the sense that if one is exposed to evidence one will automatically form the relevant beliefs without making a choice about it.
