'Conventional wisdom', based on contempt for voters, got it wrong
The decent thing to do now is to bury the conventional wisdom. Bury it in a marked grave as a reminder and a warning to others. Again and again it has led us up the garden path, again and again it has got it wrong.
The conventional wisdom was wrong about the property boom. It said there would be a 'soft landing'. We got a very hard landing. We were told the Arab Spring would be just that. Instead, Libya and Syria are waking nightmares.
Our home-grown purveyors of the conventional wisdom got our General Election wrong. They told us Fine Gael would fare pretty well and Labour better than the polls.
