I don't even know how long ago people stopped believing they had the agency to improve things in their own lives themselves, but it seems.to have coincided with the 24-hour worldwide news cycle.
It used to be that most of the bad things you found out about in the world were things you might be able to do something about. Your neighbor's car breaks down and she needs a ride to work. A family has a fire and needs furniture or clothes.
These days it's hard even to find those kinds of local mews stories. Instead you're reading about gigantic crises all over the world you can't possibly touch and need to be solved at a scale far, far removed from your influence.
I'm not saying having "low information voters" because people are illiterate or innumerate isn't a problem. I just don't think it's the primary one influencing the kinds of candidates that run or the kinds of promises that get them elected.
While there's ongoing argument about the extent to which that's a selection bias and there's other skills that aren't captured in this metric (and already were well before LLMs demonstrated that it's definitely possible to train for those tests), IQ scores do correlate with the ability to perform across those kinds of skills.

It has always been like this—just the end of a cycle, accelerated by the invention of social networks, which broke the monopoly of information gatekeeping and broadcasting, once controlled by a few TV/radio stations and newspapers. Adding to this is the outsourcing of most low-wage industries (so where most of these 18% of voters worked) to Asia. What you call a "low information voter" has always existed and will continue to exist.
