This mechanism is accentuated if the idea of reform sounds appealing at first blush: voters may respond positively to pollsters when they have not really thought the matter through, only for doubts to develop as they engage later. Examples of this abound. The most familiar in the UK is the electoral reform referendum of 2011: the idea of shaking up the political system, particularly after the expenses scandal, initially appealed to many voters; but as they engaged more, they worried about AV’s possible implications, and most ended up voting No. More strikingly still, Ireland’s voters opted in October 2013 to retain their Senate, even though polls had long shown a majority for abolition: fear of empowering the government too far changed many minds.
