Science isn’t truth. Science is a method for determining facts. Science is about asking questions and doing the best we can to find the right answers. It’s about understanding our biases as scientists and thinking “OK, now, this may be the answer I wanted / was expecting / will get me funding. Is it really true? What ELSE could be causing this? How can I look at this from a different angle? If I do, what should I expect to be the answer if I’m right?”
It’s about how to look at and think about questions in a way that gives you a way to ask the next questions. It lets you model things in a way that allows you to predict the answer to the next question. If the prediction is wrong, then so is your understanding and you need to take a step back and look at the previous question.
