A student at Rhodes College and I have been working through some of our original research on how parent-child relationships may affect political conversation.
- The Y-axis is "How comfortable are you discussing politics with parent?"
- X-axis is whether you have congruent (the same) politics as that parent, or incongruent.
- Both participant ideology and parents ideology are self-reported nominal categories by the participant (Liberal, Moderate, Conservative, Libertarian, Socialist, Other).
So it looks like the relationship is broadly that incongruent politics decreases "comfort talking about politics" but sons and mothers have a unique pattern of no correlation. Son and mother "comfort" is not affected by politics.
Also, not pictured here, these trends are the same with a Y-axis of general, non-political "I feel close to my Dad/Mom"... daughters and fathers with incongruent political beliefs lose an entire point in "closeness" but moms and sons suffer no difference whatsoever.
