If they asked, "On a scale of 1 to 10, how strongly to you believe in a creator who influences events in the world?" or "On a scale of 1 to 10, how likely are you to base an important decision on what you feel is right in God's eyes?" or "How often do you go to church?"
These would seem like objective measures of Secular-Rational Values and Traditional values. No?
Well, maybe if you were to believe the personal interpretations of each respondent. In the end, though, the answers are not ‘fact’ but interpretations and feelings.
I guess what bothers me most about the whole graph being subjective is the term “Secular-Rational” values vs. “Traditional” values as if the former were the preferable because it is rational.
To me, it seems more humanistic even though some of the questions were related to belief in God, etc.
