Jonathan Haidt (who is mentioned in the article) did a study years ago. He separated a group of people into conservatives and liberals and then gave them a questionnaire on politics. Then he got a second group, separated them, and gave them the same questionnaire. Only he asked the second group of liberals and conservatives to answer the questionnaire the way they imagined the other side would. What he found was that…
Not sure why you are getting downvotes. For anyone curious, Haidt is a liberal professor who is dedicated to figuring out how to get people talking across political ideologies. The book that covers this topic is called The Righteous Mind and is an excellent read or listen.
Conservatives didn't have "no problem" answering as liberals.
Conservatives were better able to estimate what liberals would answer for individual concerns, but were wrong about group concerns.
Moderates were better able to estimate how both groups would answer for group concerns. Both liberals and conservatives overestimated how much conservatives cared for group concerns.
Liberals underestimated how much conservatives cared for individual concerns and overestimated how much they cared for group concerns. Liberals also overestimated how much liberals cared for individual concerns and underestimated how much the cared for group concerns.
In light of that, we could even frame it as liberals see themselves closer to conservatives than vice versa. Because that's how they answered for the groups. They think there's less difference than there actually is. So they under and overestimate appropriately.
Framing it as "conservatives know liberals better than vice versa" is wrong and is a tactic to put the onus on liberals to do all the changing. Because conservatives can fill out a morality questionnaire better.
Or let me put it this way, if the question was "How many puppies is it acceptable to kick in a lifetime?"
The fact that puppy kickers were correctly able to guess "zero" for the non-kicking group while the non-kickers said the kickers would say "ten" while the kickers really said "twenty" doesn't mean that the puppy kickers are the better group.
