Note: This started as a comment on a thread at RealClimate about the Guardian’s investigation of the CRU emails fiasco. The Guardian has, until recently, had an outstandingly good record on it’s climate change reporting. It commissioned Fred Pearce to do a detailed investigation into the emails, and he published his results in a 12-part series. While some parts of it are excellent, other parts demonstrate a complete misunderstanding of how science works, especially the sections dealing with the peer-review process. These were just hopelessly wrong, as demonstrated by Ben Santer’s rebuttal of the specific allegations. In parallel, George Monbiot, who I normally respect as one of the few journalists who really understands the science, has been arguing for Phil Jones to resign as head of the CRU at East Anglia, on the basis that his handling of the FOI requests was unprofessional. Monbiot has repeated this more recently, as can be seen in this BBC clip, where he is hopelessly ineffective in combating Delingpole’s nonsense, because he’s unwilling to defend the CRU scientists adequately.
The problem with both Pearce’s investigation, and Monbiot’s criticisms of Prof Jones is that neither has any idea of what academic research looks like from the inside, nor how scientists normally talk to one another. The following is my attempt to explain this context, and in particular why scientists talking freely among themselves might seem to rude or worse. Enough people liked my comment at RC that I decided to edit it a little and post it here (the original has already been reposted at ClimateSight and Prof Mandia’s blog). I should add one disclaimer: I don’t mean to suggest here that scientists are not nice people – the climate scientists I’ve gotten to know over the past few years are some of the nicest people you could ever ask to meet. It’s just that scientists are extremely passionate about the integrity of their work, and don’t take kindly to people pissing them around. Okay, now read on…
Once we’ve gotten past the quote-mining and distortion, the worst that can be said about the CRU emails is that the scientists sometimes come across as rude or dismissive, and say things in the emails that really aren’t very nice. However, the personal email messages between senior academics in any field are frequently not very nice. We tend to be very blunt about what appears to us as ignorance, and intolerant of anything that wastes our time, or distracts us from our work. And when we think (rightly or wrongly) that the peer review process has let another crap paper through, we certainly don’t hold back in expressing our opinions to one another. Which is of course completely different to how we behave when we meet one another. Most scientists distinguish clearly between the intellectual cut and thrust (in which we’re sometimes very rude about one another’s ideas) and our social interactions (in which we all get together over a beer and bitch about the downsides of academic life). Occasionally, there’s someone who is unable to separate the two, and takes the intellectual jabs personally, but such people are rare enough in most scientific fields that the rest of us know exactly who they are, and try to avoid them at conferences.
Part of this is due to the nature of academic research. Most career academics have large egos and very thick skins. I think the tenure process and the peer review process filter out those who don’t. We’re all jostling to get our work published and recognised, often by pointing out how flawed everyone else’s work is. But we also care deeply about intellectual rigor, and preserving the integrity of the published body of knowledge. And we also know that many key career milestones are dependent on being respected (and preferably liked) by others in the field: for example, the more senior people who might get asked to write recommendation letters for us, for tenure and promotion and honors, or the scientists with competing theories who will get asked to peer review our papers.
Which means in public (e.g. in conference talks and published papers) our criticisms of others are usually carefully coded to appear polite and respectful. A published paper might talk about making “an improvement on the methodology of Bloggs et al”. Meanwhile, in private, when talking to our colleagues, we’re more likely to say that Bloggs’ work is complete rubbish, and should never have been published in the first place, and anyway everyone knows Bloggs didn’t do any of the work himself, and the only decent bits are due to his poor, underpaid postdoc, who never gets any credit for her efforts. (Yes, academics like to gossip about one another just as regular people do). This kind of blunt rudeness is common in private emails, especially when we’re discussing other scientists behind their backs with likeminded colleagues. Don’t be fooled by the more measured politeness in public: when we think an idea is wrong, we’ll tear it to shreds.
Now, in climate science, all our conventions are being broken. Private email exchanges are being made public. People who have no scientific training and/or no prior exposure to the scientific culture are attempting to engage in a discourse with scientists, and neither side understands the other. People are misquoting scientists, and trying to trip them up with loaded questions. And, occasionally, resorting to death threats. Outside of the scientific community, most people just don’t understand how science works, and so don’t know how to make sense of what’s going on.
And scientists don’t really know how to engage with these strange outsiders. Scientists normally only interact with other scientists. We live rather sheltered lives; they don’t call it the ivory tower for nothing. When scientists are attacked for political reasons, we mistake it for an intellectual discussion over brandy in the senior common room. Scientists have no training for political battles, and so our responses often look rude or dismissive to outsiders. Which in turn gets interpreted as unprofessional behaviour by those who don’t understand how scientists talk. And unlike commercial organisations and politicians, universities don’t engage professional PR firms to make us look good, and we academics would be horrified if they did: horrified at the expense, and horrified by the idea that our research might need to be communicated on anything other than its scientific merits.
Journalists like Monbiot, despite all his brilliant work in keeping up with the science and trying to explain it to the masses, just haven’t ever experienced academic culture from the inside. Hence his call, which he keeps repeating, for Phil Jones to resign, on the basis that Phil reacted unprofessionally to FOI requests. But if you keep provoking a scientist with nonsense, you’ll get a hostile response. Any fool knows you don’t get data from a scientist by using FOI requests, you do it by stroking their ego a little, or by engaging them with a compelling research idea that you need the data to pursue. And in the rare cases where this doesn’t work, you do some extra work yourself to reconstruct the data you need using other sources, or you test your hypothesis using a different approach (because it’s the research result we care about, not any particular dataset). So to a scientist, anyone stupid enough to try to get scientific data through repeated FOI requests quite clearly deserves our utter contempt. Jones was merely expressing (in private) a sentiment that most scientists would share – and extreme frustration with people who clearly don’t get it.
The same misunderstandings occur when outsiders look at how we talk about the peer-review process. Outsiders tend to think that all published papers are somehow equal in merit, and that peer-review is a magical process that only lets the truth through (hint: we refer to it more often as a crap-shoot). Scientists know that while some papers are accepted because they are brilliant, others are accepted because its hard to tell whether they are any good, and publication might provoke other scientists to do the necessary followup work. We know some published papers are worth reading, and some should be ignored. So, we’re natural skeptics – we tend to think that most new published results are likely to be wrong, and we tend to accept them only once they’ve been repeatedly tested and refined.
We’re used to having our own papers rejected from time to time, and we learn how to deal with it – quite clearly the reviewers were stupid, and we’ll show them by getting it published elsewhere (remember, big ego, thick skin). We’re also used to seeing the occasional crap paper get accepted (even into our most prized journals), and again we understand that the reviewers were stupid, and the journal editors incompetent, and we waste no time in expressing that. And if there’s a particularly egregious example, everyone in the community will know about it, everyone will agree it’s bad, and some of us will start complaining loudly about the idiot editor who let it through. Yet at the same time, we’re all reviewers, and some of us are editors, so it’s understood that the people we’re calling stupid and incompetent are our colleagues. And a big part of calling them stupid or incompetent is to get them to be more rigorous next time round, and it works because no honest scientist wants to be seen as lacking rigor. What looks to the outsider like a bunch of scientists trying to subvert some gold standard of scientific truth is really just scientists trying to goad one another into doing a better job in what we all know is a messy, noisy process.
The bottom line is that scientists will always tend to be rude to ignorant and lazy people, because we expect to see in one another a driving desire to master complex ideas and to work damn hard at it. Unfortunately the outside world (and many journalists) interpret that rudeness as unprofessional conduct. And because they don’t see it every day (like we do!) they’re horrified.
Some people have suggested that scientists need to wise up, and learn how to present themselves better on the public stage. Indeed, the Guardian published an editorial calling for the emergence of new leaders from the scientific community who can explain the science. This is naive and irresponsible. It completely ignores the nature of the current wave of attacks on scientists, and what motivates those attacks. No scientist can be an effective communicator in a world where people with vested interests will do everything they can to destroy his or her reputation. The scientific community doesn’t have the resources to defend itself in this situation, and quite frankly it shouldn’t have to. What we really need is for newspaper editors, politicians, and business leaders to start acting responsibly, make the effort to understand what the science is saying, make the effort to understand what is really driving these swiftboat-style attacks on scientists, and then shift the discourse from endless dissection of scientists’ emails onto useful, substantive discussions of the policy choices we’re faced with.
[Update: Joe Romm has reposted this at ClimateProgress, and it's generated some very interesting discussion, including a response from George Monbiot that's worth reading]
[Update 2: 31/3/2010 The UK Parliament released its findings last night, and completely exonerates Prof. Jones and the CRU. It does, however, suggest that the UEA should bear responsibility for any mistakes that were made over how the FoI requests were handled, and it makes a very strong call for more openness with data and software from the climate science community]
