Open access is in the news again.
Index on Censorship held a debate on open data on December 6th.
The video of of the meeting is now on YouTube. A couple of dramatic moments in the video: At 48 min O’Neill & Monbiot face off about "competent persons" (and at 58 min Walport makes fun of my contention that it’s better to have more small grants rather than few big ones, on the grounds that it’s impossible to select the stars).

The meeting has been written up on the Bishop Hill Blog, with some very fine cartoon minutes.
It was gratifying that my remarks seemed to be better received by the scientists in the audience than they were by some other panel members. The Bishop Hill blog comments "As David Colquhoun, the only real scientist there and brilliant throughout, said “Give them everything!” " Here’s a subsection of the brilliant cartoon minutes
The bit about "I just lied -but he kept his job" referred to the notorious case of Richard Eastell and the University of Sheffield.
We all agreed that papers should be open for anyone to read, free. Monbiot and I both thought that raw data should be available on request, though O’Neill and Walport had a few reservations about that.
A great deal of time and money would be saved if data were provided on request. It shouldn’t need a Freedom of Information Act (FOIA) request, and the time and energy spent on refusing FOIA requests is silly. It simply gives the impression that there is something to hide (Climate scientists must be ruthlessly honest about data). The University of Central Lancashire spent £80,000 of taxpayers’ money trying (unsuccessfully) to appeal against the judgment of the Information Commissioner that they must release course material to me. It’s hard to think of a worse way to spend money.
A few days ago, the Department for Business, Innovation and Skills (BIS) published a report which says (para 6.6)
“The Government . . . is committed to ensuring that publicly-funded research should be accessible
free of charge.”
That’s good, but how it can be achieved is less obvious. Scientific publishing is, at the moment, an unholy mess. It’s a playground for profiteers. It runs on the unpaid labour of academics, who work to generate large profits for publishers. That’s often been said before, recently by both George Monbiot (Academic publishers make Murdoch look like a socialist) and by me (Publish-or-perish: Peer review and the corruption of science). Here are a few details.
Extortionate cost of publishing
Mark Walport has told me that
The Wellcome Trust is currently spending around £3m pa on OA publishing costs and, looking at the Wellcome papers that find their way to UKPMC, we see that around 50% of this content is routed via the “hybrid option”; 40% via the “pure” OA journals (e.g. PLoS, BMC etc), and the remaining 10% through researchers self-archiving their author manuscripts.
I’ve found some interesting numbers, with help from librarians, and through access to The Journal Usage Statistics Portal (JUSP).
Elsevier
UCL pays Elsevier the astonishing sum of €1.25 million, for access to its journals. And that’s just one university. That price doesn’t include any print editions at all, just web access and there is no open access. You have to have a UCL password to see the results. Elsevier has, of course, been criticised before, and not just for its prices.
Elsevier publish around 2700 scientific journals. UCL has bought a package of around 2100 journals. There is no possibility to pick the journals that you want. Some of the journals are used heavily ("use" means access of full text on the web). In 2010, the most heavily used journal was The Lancet, followed by four Cell Press journals
But notice the last bin. Most of the journals are hardly used at all. Among all Elsevier journals, 251 were not accessed even once in 2010. Among the 2068 journals bought by UCL, 56 were never accessed in 2010 and the most frequent number of accesses per year is between 1 and 10 (the second bin in the histogram, below). 60 percent of journals have 300 or fewer usages in 2010, Above 300, the histogram tails on up to 51878 accesses for The Lancet. The remaining 40 percent of journals are represented by the last bin (in red). The distribution is exceedingly skewed. The median is 187, i.e. half of the journals had fewer than 187 usages in 2010), but the mean number of usages (which is misleading for such a skewed distribution, was 662 usages).
Nature Publishing Group
UCL bought 65 journals from NPG in 2010. They get more use than Elsevier, though surprisingly three of them were never accessed in 2010, and 17 had fewer than 1000 accesses in that year. The median usage was 2412, better than most. The leader, needless to say, was Nature itself, with 153,321.
Oxford University Press
The situation is even more extreme for 248 OUP journals, perhaps because many of the journals are arts or law rather than science.
The most frequent (modal) usage of was zero (54 journals), followed by 1 to 10 accesses (42 journals) 64 percent of journals had fewer than 200 usages, and the 36 percent with over 200 are pooled in the last (red) bin. The histogram extends right up to 16060 accesses for Brain. The median number of usages in 2010 was 66.
So far I haven’t been able to discover the costs of the contracts with OUP or Nature Publishing group. It seems that the university has agreed to confidentiality clauses. This itself is a shocking lack of transparency. If I can find the numbers I shall -watch this space.
Almost all of these journals are not open access. The academics do the experiments, most often paid for by the taxpayer. They write the paper (and now it has to be in a form that is almost ready for publication without further work), they send is to the journal, where it is sent for peer review, which is also unpaid. The journal sells the product back to the universities for a high price, where the results of the work are hidden from the people who paid for it,
It’s even worse than that, because often the people who did the work and wrote the paper, have to pay "page charges". These vary, but can be quite high. If you send a paper to the Journal of Neuroscience, it will probably cost you about $1000. Other journals, like the excellent Journal of Physiology, don’t charge you to submit a paper (unless you want a colour figure in the print edition, £200), but the paper is hidden from the public for 12 months unless you pay $3000,
The major medical charity, the Wellcome Trust, requires that the work it funds should be available to the public within 6 months of publication. That’s nothing like good enough to allow the public to judge the claims of a paper which hit the newspapers the day that it’s published. Nevertheless it can cost the authors a lot. Elsevier journals charge $3000 except for their most-used journals. The Lancet charges £400 per page and Cell Press journals charge $5000 for this unsatisfactory form of open access.
Open access journals
The outcry about hidden results has resulted in a new generation of truly open access journals that a open to everyone from day one. But if you want to publish in them you have to pay quite a lot.
Furthermore, although all these journals are free to read, most of them do not allow free use of the material they publish. Most are operating under all-rights-reserved copyrights. In 2009 under 10 percent of open access journals had true Creative Commons licence.
Nature Publishing Group has a true open access journal, Nature Communications, but it costs the author $5000 to publish there. The Public Library of Science journals are truly open access but the author is charged $2900 for PLoS Medicine though PLoS One costs the author only $1350
A 2011 report considered the transition to open access publishing but it doesn’t even consider radical solutions, and makes unreasonably low estimates of the costs of open access publishing.
Scam journals have flourished under the open access flag
Open access publishing has, so far, almost always involved paying a hefty fee. That has brought the rats out of the woodwork and one gets bombarded daily with offers to publish in yet another open access journal. Many of these are simply scams. You pay, we put it on the web and we won’t fuss about quality. Luckily there is now a guide to these crooks: Jeffrey Beall’s List of Predatory, Open-Access Publishers.
One that I here from regularly is Bentham Open Journals
(a name that is particularly inappropriate for anyone at UCL). Jeffery Beall comments
"Among the first, large-scale gold OA publishers, Bentham Open continues to expand its fleet of journals, now numbering over 230. Bentham essentially operates as a scholarly vanity press."
They undercut real journals. A research article it The Open Neuroscience Journal will cost you a mere $800. Although these journals claim to be peer-reviewed, their standards are suspect. In 2009, a nonsensical computer-generated spoof paper was accepted by a Bentham Journal (for $800),
What can be done about publication, and what can be done about grants?
Both grants and publications are peer-reviewed, but the problems need to be discussed separately.
Peer review of papers by journals
One option is clearly to follow the example of the best open access journals, such as PLoS. The cost of $3000 to $5000 per paper would have to be paid by the research funder, often the taxpayer. It would be money subtracted from the research budget, but it would retain the present peer review system and should cost no more if the money that were saved on extortionate journal subscriptions were transferred to research budgets to pay the bills, though there is little chance of this happening.
The cost of publication would, in any case, be minimised if fewer papers were published, which is highly desirable anyway.
But there are real problems with the present peer review system. It works quite well for journals that are high in the hierarchy. I have few grumbles myself about the quality of reviews, and sometimes I’ve benefitted a lot from good suggestions made by reviewers. But for the user, the process is much less satisfactory because peer review has next to no effect on what gets published in journals. All it influences is which journal the paper appears in. The only effect of the vast amount of unpaid time and effort put into reviewing is to maintain a hierarchy of journals, It has next to no effect on what appears in Pubmed.
For authors, peer review can work quite well, but
from the point of view of the consumer, peer review is useless.
It is a myth that peer review ensures the quality of what appears in the literature.
A more radical approach
I made some more radical suggestions in Publish-or-perish: Peer review and the corruption of science.
It seems to me that there would be many advantages if people simply published their own work on the web, and then opened the comments. For a start, it would cost next to nothing. The huge amount of money that goes to publishers could be put to better uses.
Another advantage would be that negative results could be published. And proper full descriptions of methods could be provided because there would be no restrictions on length.
Under that system, I would certainly send a draft paper to a few people I respected for comments before publishing it. Informal consortia might form for that purpose.
The publication bias that results from non-publication of negative results is a serious problem, mainly, but not exclusively, for clinical trials, It is mandatory to register a clinical trial before it starts, but many of the results never appear. (see, for example, Deborah Cohen’s report for Index on Censorship). Although trials now have to be registered before they start, there is no check on whether or not the results are published. A large number of registered trials do not result in any publication, and this publication bias can costs thousands of lives. It is really important to ensure that all results get published,
The ArXiv model
There are many problems that would have to be solved before we could move to self-publication on the web. Some have already been solved by physicists and mathematicians. Their archive, ArXiv.org provides an example of where we should be heading. Papers are published on the web at no cost to either user or reader, and comments can be left. It is an excellent example of post-publication peer review. Flame wars are minimised by requiring users to register, and to show they are bona fide scientists before they can upload papers or comments. You may need endorsement if you haven’t submitted before.
Peer review of grants
The problems for grants are quite different from those for papers. There is no possibility of doing away with peer review for the award of grants, however imperfect the process may be. In fact candidates for the new Wellcome Trust investigator awards were alarmed to find that the short listing of candidates for their new Investigator Awards was done without peer review.
The Wellcome Trust has been enormously important for the support of medical and biological support, and never more than now, when the MRC has become rather chaotic (let’s hope the new CEO can sort it out). There was, therefore, real consternation when Wellcome announced a while ago its intention to stop giving project and programme grants altogether. Instead it would give a few Wellcome Trust Investigator Awards to prominent people. That sounds like the Howard Hughes approach, and runs a big risk of “to them that hath shall be given”.
The awards have just been announced, and there is a good account by Colin Macilwain in Science. UCL did reasonable well with four awards, but four is not many for a place the size of UCL. Colin Macilwain hits the nail on the head.
"While this is great news for the 27 new Wellcome Investigators who will share £57 million, hundreds of university-based researchers stand to lose Wellcome funds as the trust phases out some existing programs to pay for the new category of investigators".
There were 750 applications, but on the basis of CV alone, they were pared down to a long-list if 173. The panels then cut this down to a short-list of 55. Up to this point no external referees were used, quite unlike the normal process for award of grants. This seems to me to have been an enormous mistake. No panel, however distinguished, can have the knowledge to distinguish the good from the bad in areas outside their own work, It is only human nature to favour the sort of work you do yourself. The 55 shortlisted people were interviewed, but again by a panel with an even narrower range of expertise, Macilwain again:
"Applications for MRC grants have gone up “markedly” since the Wellcome ones closed, he says: “We still see that as unresolved.” Leszek Borysiewicz, vice-chancellor of the University of Cambridge, which won four awards, believes the impact will be positive: “Universities will adapt to this way of funding research."
It certainly isn’t obvious to most people how Cambridge or UCL will "adapt" to funding of only four people.
The Cancer Research Campaign UK has recently made the same mistake.
One problem is that any scheme of this sort will inevitably favour big groups, most of whom are well-funded already. Since there is some reason to believe that small groups are more productive, it isn’t obvious that this is a good way to go, I was lucky enough to get 45 minutes with the director of the Wellcome Trust, Mark Walport, to put these views. He didn’t agree with all I said, but he did listen.
One of the things that I put to him was a small statistical calculation to illustrate the great danger of a plan that funds very few people. The funding rate was 3.6% of the original applications, and 15.6% of the long-listed applications. . Let’s suppose, as a rough approximation, that the 173 long-listed applications were all of roughly equal merit. No doubt that won’t be exactly true, but I suspect it might be more nearly true than the expert panels will admit. A quick calculation in Mathcad gives this, if we assume a 1 in 8 chance of success for each application.
And this gloomy outcome supposed that you made 8 grant applications -an enormous amount of work. If you submitted four applications then you have a nearly 60% chance of getting nothing at all, and only a i in 3 chance of getting one grant.
These results arise regardless of merit, purely as consequence of random chance. They are disastrous, and especially disastrous for the smaller, better-value, groups for which a gap in funding can mean loss of vital expertise. It also has the consequence that scientists have to spend most of their time not doing science, but writing grant applications. The mean number of applications before a success is 8, and a third of people will have to write 9 or more applications before they get funding. This makes very little sense.
Grant-awarding panels are faced with the near-impossible task of ranking many similar grants. The peer review system is breaking down, just as it has already broken down for journal publications.
I think these considerations demolish the argument for funding a small number of ‘stars’. The public might expect that the person making the application would take an active part in the research. Too often, now, they spend most of their time writing grant applications. What we need is more responsive-mode smallish programme grants and a maximum on the size of groups.
Conclusions
We should be thinking about the following changes,
- Limit the number of papers that an individual can publish. This would increase quality, it would reduce the impossible load on peer reviewers and it would reduce costs.
- Limit the size of labs so that more small groups are encouraged. This would increase both quality and value for money.
- More (and so smaller) grants are essential for innovation and productivity.
- Move towards self-publishing on the web so the cost of publishing becomes very low rather than the present extortionate costs. It would also mean that negative results could be published easily and that methods could be described in proper detail.
