The Daniel Finkelstein (pbuh) has noted that David Cameron’s parting has moved from one side of his head to the other. Clearly, quoting The Who was what had to be done there.

However, as one very decent economist will point out to you, namely Glenn Whitman, this is the start of something much more serious. Yes, I’m afraid it’s true, leave aside whether the Boy Dave (C) is marginally left of centre of marginally right of it, this is really serious.

It seems obvious there must be some degree of self-deception going on.

Could be, could be.

They must believe that others don’t notice. But how did they get there? What
psychological mechanism facilitates this level of delusion?

A bit harsh there Glenn.

Naturally, I have a theory.  I surmise that it didn’t happen all at once, but by degrees.

Indeed: chasing the centre ground and before you know it you’re praising Polly Toynbee.

I conclude that he has fallen victim to a version of the sorites paradox,
also known as the paradox of the heap. This paradox shows that when a
concept has vague or fuzzy boundaries, it’s possible to move, by a
series of individually logical or sensible steps, to an outcome that is
thoroughly untenable.

Well, there are those who think it entirely tenable but I’m with you here Professor.

For instance, if you start with a heap of sand, you can always remove
one grain of sand and still have a heap. But apply that premise
repeatedly, and you’ll eventually conclude that a single grain of sand
constitutes a heap.

Or a Tory Party of course.

No, sorry, actually, it’s even worse than that. This is the start of the comb-over.
