People who are ill informed can also have a high level of common sense.
I think the issue can arise from life experience.
Working class people (for want of a better description) imo generally have more common sense in certain areas because their life experiences come from living in a world, where they are more likely to be involved in violence, crime and people who want to rip them off.
We call it ‘street smart’.
Street smarts allow you to spot someone who’s no good pretty quickly and is a very transferable skillset imo when it comes to politics. Of course there are degrees of it and how it is deployed.
On the other hand, an educated person who has almost non of these experiences is open to vastly more amounts of manipulation. They are especially susceptible to appeals to empathy because they aren’t street smart. They don’t have much experience of when someone is exploiting that.
Again not a be all and end all but I believe a valid position as to why common sense ‘street smarts’ is potentially more valuable than a university degree, when it comes to spotting good ir bad ideas, by good or bad people.
