There is a lot of stereotyping, and it doesn’t account for the interest axis, i.e. the fact that a lot of very smart people simply do not care for organised politics in any way, shape, or form.
More importantly, it lacks knowledge of consensus mechanics beyond Overton, which is why it struggles to get to grip with the right side of the spectrum - which is, historically speaking, the most consistently successful side, at least in the short or medium term when any new political issue arises. Dismissing that as “I don’t know” shows embarrassingly poor subject knowledge.
So uhm, this piece could have been written by a 16-year-old trying to move his brain for the first time. That it comes from a much older and experienced person, somebody who holds a number of smart positions on other topics, to me is a signal that such person has done very little effort to actually study this particular field in depth.
Maybe it’s an attempt at showing that one can be not-smart about certain topics? If that were the case, I don’t think we really need it - Twitter and Facebook remind us every hour of every day that it is indeed the case.
