Within the context of Brexit, the leavers had their own group of "experts" i.e. the ERG but any attempt at economic prediction was clearly shunned on the grounds of it being "Project Fear" despite no specific biases being demonstrated. Because that's the only way, along with blatant lies, to get people believe that leaving the largest trading block - possibly even with no replacement deal with anyone - could possibly be a good thing (At all costs being the current mantra i.e. No Deal)
It's not the lack of listening to certain experts that bothers me, it's them clearing playing the card. Gove, and most of the others on the leave side, is very well educated and damn well knows that careful thought ("expert"ism) is important.
