I do not like the question – do you believe in this/that scientific theory? that is a stupid question to ask. the questions should be – do you understand this/that scientific theory and its strengths and weaknesses and how the scientists came to a consensus to formulate this theory? if you think it is weak, do you think that is because of a lack of scientific studies, or because it goes against yours or your group’s economic/social/political/religious interests? and if you have an alternate theory to a different topic, is your theory based on empirical data, or is it based on stories your parents told you while you were growing up?
that is how the questions should be phrased.
