Epistemic rationality is about conforming our beliefs to the evidence avaialble. Rationality and truth are not the same thing; if all the evidence supports a falsehood, then it is rational to believe it despite its falsehood. Likewise, something may be true, yet irrational to believe - considering the example above, Tom's belief that his teacher is an adulterer is irrational, since he bases his belief on unreliable evidence; it may well be that his teacher is ''in fact'' an adulterer, but while Tom's belief would then be true, it would still be irrational ''for Tom'', since Tom lacks any good evidence for that belief.
