I would put myself way higher on the openness trait (probably 99%), and I think my friends and family would agree with that; at least openness to ideas, maybe less openness to experience. As an example of possibly being less open to experience: I’ve never done (recreational) drugs (except alcohol) — although it feels to me like it’s coming from a sound concern for identity preservation and health. As for other conservative ideas I'm "open" to, it seems to be coming from a place of openness to ideas (to the idea that some traditions can play a valuable role or something like that) and not from a place of feeling a strong pressure to follow traditions. I’ve also read that openness could be tracking interest in “art and literature and music” — in which case 70% makes more sense to me.
