I agree with Adirian. Rationalization is a process of rational-explanation-seeking. It starts from statement that was obtained by non-rational process (as when you overheard something, or intuitively guessed something) and then creates a rational explanation according to one’s concept of rationality, concurrently adjusting statement if necessary. So normal rationalization does change the conclusion: it can change its status from ‘suspicious statement’ to ‘belief’, or it can adjust it to be consistent with facts. Now biased rationalization uses ‘biased rationality’ according to which it builds explanation, for example that ‘clever arguer’ applies selection bias.
