I’ve thought this a very long time ago. We are trained since elementary school to come up with guesses. You are not allowed to say I don’t know. You must come up with something. This is not bad necessarily at this stage because your brain has to develop, making suppositions but later in high school making guesses is encouraged rather than saying I don’t know. I think this is terrible for science and society. You don’t know if a person really knows what he’s talking about or is just taking a wild shot. But if it’s a wild shot by a writer, another writer takes it as truth, and on and on.
