08 Nov Peanuts, ecstasy, and the perils of scientific advice to government

Writing in the New Scientist, David Nutt, recently fired as chair of Britain’s scientific advisory council on the misuse of drugs, offers cogent thoughts on the nature of scientific advice to government. Moneyquote:

I can trace the beginning of the end of my role as chairman of the UK’s official advisory body on drugs to the moment I quoted a New Scientist editorial (14 February, p 5). Entitled, fittingly enough, “Drugs drive politicians out of their minds”, the editorial asked the reader to imagine being seated at a table with two bowls, one containing peanuts, the other the illegal drug MDMA (ecstasy). Which is safer to give to a stranger? Why, the ecstasy of course.

I quoted these words in the Eve Saville lecture at King’s College London in July. This example plus other comments I have made – such as horse riding is more harmful than ecstasy – prompted Alan Johnson, the home secretary, to say that I had crossed the line from science to policy. This, he said, is why I had to go.

But simple, accurate and understandable statements of scientific fact are precisely what the advisory council is supposed to provide…

More after the jump.

Policies that ignore the realities of the world we live in are doomed to fail. This is true for just about all the biggest issues that we confront, from energy and climate to criminal justice, health and immigration. I’m not arguing that science dictate policy; considerations such as cost, practicality and morality also have a role. But scientific evidence should never be brushed aside from the political debate.

The current British government has said repeatedly that it wants its policies to be evidence-based, but actions speak louder than words. On ecstasy, for example, it made policy first, sought advice second – and cynically rejected the advice it was given. The result is shambolic policy-making which gives great cause for concern if that is how governments operate more generally.
