The European Union has decided that it is going to abolish the role of chief scientific adviser. The usual suspects are outraged but in reality I can't see why this should be a problem for policymakers. There is no particular reason why the advice of a cell biologist like Anne Glover - the last incumbent of the role at the EU - should be important in the debate over, say, climate change. Many readers of this blog could lay claim to as much or more expertise than the good professor, brilliant individual though she may be in her own field.
Moreover, much of the demand for CSAs in government is driven by a wish to keep pressure on policymakers to fund science and scientists. CSAs end up as public-funded shop stewards, a shameful thing.
If policymakers want advice on particular subjects, let them go to experts in the area concerned.
