Paul Krugman on open-mindedness

From Ideology and Integrity (back in May 2015):

Times like these call for a combination of open-mindedness — willingness to entertain different ideas — and determination to do the best you can. ... Everyone has an ideology, a view about how the world does and should work. Indeed, the most reckless and dangerous ideologues are often those who imagine themselves ideology-free ... and are, therefore, unaware of their own biases. What you should seek, in yourself and others, is not an absence of ideology but an open mind, willing to consider the possibility that parts of the ideology may be wrong.

I've been quite critical of Krugman's writing in this regard before - its not clear to me that he lives up particularly well to what he claims above. However, in what he says above I think he's right.
