The Cox-Ince controversy rumbles on, apparently…

Open Parachute

Popular science presenters like Brian Cox are sometimes criticised by colleagues suffering from a bit of professional jealousy – although it’s a lot better than in the old days. I think most scientists today recognise the need for good science communication with the public – who, after all, are financing our science through the taxation system.

Brian Cox and his mate Robin Ince wrote a recent New Statesman editorial promoting a better understanding of the nature of science and its role in public decision-making (see Politicians must not elevate mere opinion over science). It made some good points – but upset some people. The jealousy this time seems to come from a few historians and sociologists – and not scientists themselves.

I think their criticism reveals an unfortunate attitude towards the scientific process, or indeed a misunderstanding of that process. Nevertheless, the debate does reveal some aspects of the…

Science and Politics

It’s a dark dreary December day with a downright deluge descending outside to add to the alliteration.  Fortunately, it being almost Christmas, this weekend is offering a glut of crosswords with which I’ve been occupying myself while waiting for a break in the rain.

Among the puzzles I’ve done was a moderately challenging one in the New Statesman.  I have a subscription to the New Statesman, which means that I get it delivered in the post approximately two days after everyone else has had a chance to read it. After finishing the crossword, which contain a number of hidden (unclued) famous pseudonyms, I had a look at the rest of the magazine and discovered that this issue, the Christmas one, was edited by Brian Cox (who needs no introduction) and Robin Ince (who I believe is a comedian of some sort). It’s nice to see science featured so strongly in a political magazine, of course, but I did raise an eyebrow when I read this (about the LHC) in a piece written by Professor Cox:

The machine itself is 27 kilometres in circumference and is constructed from 9,300 superconducting electromagnets operating at -271.3°C. There is no known place in the universe that cold outside laboratories on earth…

Not so. The cryogenic systems on ESA’s Planck mission achieved a stable operating temperature at the 0.1 K level. This experiment has now reached the end of its lifetime and is warming up, but  the Herschel Space Observatory with a temperature of 1.4 K is still cooler than the Large Hadron Collider. Moreover, there are natural phenomena involving very low temperatures. The Boomerang Nebula has a measured temperature of −272.15°C, also lower than the LHC.  How does this system manage to cool itself down below the temperature of the cosmic microwave background, I hear you asking.  A detailed model is presented here; it’s “supercooled” because it is expanding so quickly compared to the rate at which it is absorbing CMB photons.

Anyway, if this all seems a bit pedantic then I suppose it is, but if prominent science advocates can’t be bothered to check their facts on things they claim to be authorities about, one wonders why the public show pay them any attention in the broader sphere. Fame and influence bring with them difficult responsibilities.

That brings me to another piece in the same issue, this one co-authored by Cox and Ince, about Science and Society entitled Politicians must not elevate mere opinion over science. I’d realised that there was a bit of a Twitter storm brewing about this item, but had to wait until the horse and cart arrived with my snail mail copy before I could try figure out what it was about. I still haven’t because although it’s not a particularly focussed piece it doesn’t seem to say anything all that controversial. In fact it just struck me that it seems to be a bit self-contradictory, on the one hand arguing that politicians should understand science better and on the other calling for a separation of science and politics.   There are two more detailed rejoinders here and here.

For my part I’ll just say that I think it is neither possible nor desirable to separate science from politics.  That’s because, whether we like it or not, we need them both. Science may help us understand the world around us, and (to a greater or lesser degree of reliability) predict its behaviour, but it does not make decisions for us. Cox and Ince argue that

Science is the framework within which we reach conclusions about the natural world. These conclusions are always preliminary, always open to revision, but they are the best we can do.

I’d put it differently, in terms of probabilities and evidence rather than “conclusions”, but I basically agree. The problem is that at some point we have to make decision which may not depend solely on the interpretation of evidence but on a host of other factors that science can say nothing about. Definite choices have to be made, even when the evidence is ambiguous. In other words we have to bring closure, much as we do when a jury delivers a verdict in a court of law, which is something that science on its own can rarely do. Mere opinion certainly counts in that context, and so it should. The point is that science is done by people, not machines. People decide what questions to ask, and what assumptions to proceed from. Choices of starting point are political (in the widest sense of the word) and sometimes what you get out of a scientific investigation  is little more than what you put in.

It’s always going to a problem in a democratic society that scientific knowledge is confined to a relatively small number of experts. We can do our best to educate as many as possible about what we do, but we’re always going to struggle to explain ourselves adequately. There will always be conspiracy theories and crackpots of various kinds. The way to proceed is not to retreat into a bunker and say “Trust me, I’m a scientist” but to be more open about the doubts and uncertainties and to present a more realistic picture of the strengths and limitations of science. That means to engage with public debate, not by preaching the gospel of science as if it held all the answers, but by acknowledging that science is a people thing and that as such it belongs in politics as much as politics belongs in it.
