For example, "could my belief all the experts are wrong on No-Deal and Brexit stem from that being the most convenient outcome for my own politics?"
I really don't know how to answer that.
Of course it's a possibility, but giving expert advice is about saying what you think at the conviction level you think it.
I think doing so abruptly, chaotically and without a transition period will be disruptive.
I think so pretty strongly 🤷♂️.
