Lakoff in 'Moral Politics' talks about how competing models of family influence policy and politics debates in the US. This model duality is not only present in a variety of contexts but I would claim is the very foundation of all policy discourse (argument). In other words, whereever you look at a policy controversy you see a conflict of framings and foregrounding. Here's a good example I culled from two recent podcasts.

Matt Miller has a radical but simple proposal to improve the nation's public schools: federalize funding to eliminate disparities in per-pupil funding between poor and affluent communities. He also proposes a single set of federal standards for math, science and reading, instead of letting each state set its own standards. Scott Simon speaks with Miller, a senior fellow at the Center for American Progress.

How can government create policies that interact with – rather than police - human behaviour? DAVID WILLETTS, Shadow Secretary for Innovation, Universities and Skills, argues that politicians could learn something from the recent surge in the study of human behaviour by game theorists, evolutionary biologists and neurologists. David Willetts will be delivering the Michael Oakeshott memorial lecture on The Ideas that are Changing Politics on Wednesday 20 February at the London School of Economics.

Quite independently, the progressive Matt Miller and conservative David Willetts have provided a great example of retrenchment of two basic models of governance. 1. Local people know best and don't need interference from removed centrals of power. 2. Local people are ignorant and need central control to make sure they don't make a mess of things.

These two models are negotiated in a variety of contexts all over the place. They are given 'scholarly' support and 'narrative' support (the two being often just two sides of the same coin) on almost daily basis. We can also think of stories (real or fictional) where one or the other will apply. For instance, teachers talk about the National Curriculum in the UK today or Voter registration drives in the 1960s in the US south. Plus we could probably list several film and TV storylines that playout one or the other scenario with great conviction.

Now, both Willetts and Miller seem to make good points. How do we decide? Negotiation of framing and generative as well as constitutive metaphors.
