An Insight

One point that the pandemic has brought home to me is just how narrow people's expertise is. I'm regularly surprised by how a celebrated professor of X can exhibit a sub-college-level understanding of Y, even when X and Y are related. /1

Indeed.  One of the greatest harms is when "experts" don't stay their lanes.  Sometimes it results in wonderful cross-pollination but frequently it is a disaster.  To be an expert, particularly an academic expert, is usually a function of high IQ in combination with sustained focus.  This can lead to a false sense of universal expertise rather than narrow expertise.  Humility is the answer but only a few epistimic frameworks cultivate humility.
