I mean holding something up, looking at it in a fresh light, considering an alternative view, listening to the opposite argument, assessing and weighing the evidence.
Sceptical skills do not come naturally to us and I think we should practice them. Argue with yourself against some deeply-held opinions for a few minutes each day, perhaps. 1
I think we should cultivate the friendship of the smart, good people who despite being smart and good, believe all the wrong things.
We should celebrate when we change our mind or arrive at a fresh perspective. These are moments that don’t come round so often. It’s much more common, apparently, only to really latch on to the fresh information that digs us deeper into the rut we have already chosen.
And finally we should train our sceptical gunsights on those who who are on our side, who are bravely fighting our corner. It isn’t wrong. It’s breathing clean air.
