It is harder to answer the question 'What do you think?' than the question 'What do you feel?'. It may be harder to put feelings into words, but that may not be necessary. All that may be needed is a Good/Bad or Yes/No response. We can have visceral emotional reactions to issues and questions we have little knowledge about. Intuition is always on. Thought has to be turned on. We may not have the tools required to think about the issue. Thinking may require hard work. Most of our beliefs and opinions are based on how we feel.
