I have previously posted about his pitifully poor critical thinking skills and inability to grasp complex and nuanced arguments.
He is of around average intelligence at best, which through the prism of the job he holds makes him stupid. It’s actually astonishing to me that someone so manifestly lacking in intellect holds the position he does, but his professional standing does not of itself demonstrate his intelligence, but rather his output within that role, which displays a conspicuous inability to advance an argument in a balanced, considered and well thought out way. The fact he is calculating is neither here nor there. Plenty of calculating people are thick.
