Concepts about evidence

Use information based on good science.

Any claim should be backed up by reliable, relevant evidence. Unfortunately, not all evidence is created equal.  Sometimes people distort or selectively report the science behind their favoured claim.  Or there might be multiple studies that appear to contradict one another. Studies should make fair comparisons, designed to minimize the risk of systematic errors (biases) and random errors (the play of chance).

Use information based on good science and always ask: “Is the evidence reliable?”
