On the other hand... that's exactly what it means to be human, and is not the flaw that it is often made out to be in the literature. We as people both forward-chain and backward-chain. If I have principles that are important to me, I might reason forward from them to plan or conclude. And then if I discover an undesirable outcome, then that means I've learned something about myself, and then I can reason backwards to adjust what my principle actually is, and reason forward from that adjustment. There's nothing morally wrong with learning and evolving. It doesn't by definition mean we're inconsistent.
