There are many policies and courses of action that reflect good ideas, but are imperfectly or poorly implemented. On my wedding day, I was trying to make efficient use of time making final arrangements before the ceremony by talking to a friend about one task whilst walking backwards in the direction of my next task. As I finished the conversation, I turned forwards whilst maintaining my momentum and promptly walked into a door that I had not realised 
was behind me, leaving a clearly obvious cut down my forehead for day (see right). Alongside finding it hilarious, my partner did ask why I had not thought more carefully about where I was walking. While I accepted the criticism of that question, I retained that my attempts to work efficiently on that morning were to be commended. We continue to disagree on whether the merit of my aim outweighs the demerit of my execution.
The same tension arises elsewhere. In the current UK university climate, departments are assessed, amongst other things, on the extent to which their research has influence beyond the academic community. A few weeks ago David argued that there are good reasons for academics to think about how their work has political influence and I think these reasons offer some support for assessing research ‘impact’. However, many people criticise how this assessment is implemented. Questions have been raised whether it places too much weight on easily observable, short-term impact. Such criteria would be problematic if, for example, they would not identify, and would, thereby, discourage, the immense and sustained impact of Pythagoras Theorem because many of its impacts have developed from other disciplines using it in applied research many years later. If such criticisms have merit, we, again, face the question: how should we balance valuing a policy’s basic form against valuing (or disvaluing) some of its substance?
