btw, any yes/no question that includes the phrase "or not" cannot be properly answered.
for example, "Do you believe in X, or not" is a nonsense yes/no question. If I say "yes" am I saying that I believe in X or that I do not believe in X. Both are valid interpretations of the answer for the question as asked.
poorly structured survey, IMO.
Removing "or not" from several questions would make it more clear.
