I wonder what would be a more personal (and interesting) question than:
- Describe your relationship with your mother
- Describe your relationship with your father
Completely open-ended, yet, is universal to everyone. Being candid in that area can provide a lot of foundational underpinning to understand someone.
But - would people find it awkward? Would they take offense? Feel pain thinking about the answer?
As for someone's political opinion in a specific area, I'm worried self-presentation pressures and social environment crafts us to more heated (or passive, to not make a stir) for us to conform. In fact, on that subject, Wikipedia's page on this area is amazing: https://en.wikipedia.org/wiki/Conformity
The thing is - isn't the interesting thing someone's true hardships, needs, dreams, interpretations of life events, and desires, rather than something stemming from an idealized image they want to portray others, to be "good"? When social pressures of trying to say things the "right way", it's not a good read. Sure, they may be lashing out at others in outrage. Perhaps its very righteous and personal (most of the time?)
But what if, paradoxically, they're doing it out of pressure to be apart of the herd so they themselves are not ostracized? https://en.wikipedia.org/wiki/Self-monitoring
So I worry that even if we ask sensitive questions, there will be so much splitting, and so many people who are coy on their responses so as to avoid the people who really make a fuss of stuff. Maybe we'd find people are scared to validate their true feelings and needs. What if environment and fear of being an outcast/ridiculed for showing candor has them in a compliance state?
And that'd take us back to psychoanalysts in the 1940's and 50's :) https://en.wikipedia.org/wiki/Karen_Horney#Theory_of_neurosi..., https://en.wikipedia.org/wiki/Character_orientation. It's hard to come up with a new idea in this space.
