It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.\n\n\u2014 William K. Clifford, Ethics of Belief\n\nWe all like to think that we are wise, that our opinions are well thought out, and that we\u2019re smart enough to spot when we have inconsistent beliefs. Today I want to talk about why believing something without sufficient evidence is wrong, and that idea that how we come to a belief or a conclusion is more important that the whether the belief or conclusion is correct.
