An accusation constantly levelled at the current Labour Party is it operates by focus group, moving position, designing policy, according to what people say in those things.
It’s no more true of them than anyone, I suppose, although they do have that feel of twisting in the wind at the moment.
Risky things, focus groups. Sometimes we do them at newspapers and they’re not, putting it mildly, 100% accurate. The results vary, because people feel obligated to tell you what you want to hear, or take the chance to say something outrageous.
