When I’m worried about bias in the answer, I do by best to no inject my opinions or thoughts into the question. Sometimes I go a step further and ask the question with the opposite bias and leading thoughts of what I think the answer is or should be, to see if it tells me I’m wrong and corrects me to the thing I secretly thought it would be (or hoped it would be). This gives me more solid footing to believe it’s not just telling me what I want to hear.
