Select Committee on Science and Technology Minutes of Evidence


Examination of Witnesses (Questions 1120-1139)

PROFESSOR SIR GORDON CONWAY KCMG, PROFESSOR PAUL WILES AND PROFESSOR FRANK KELLY

7 JUNE 2006

  Q1120  Mr Newmark: Do any of your departments publish all research that is used to underpin policy development?

  Professor Wiles: Any social research within the Home Office is published subject to three constraints. The first one is that I say it is of good enough quality to be published. When I say "I say" actually what happens is we have external and independent peer review and on the basis of that peer review I then take the decision as to whether it should be published. If I decide, as a result of peer review, it is not good enough to be published, if it is external research the authors are then free to seek publication if they can. The other two conditions in which I might constrain publication are first of all if I think it is in the national interest not to. I have done that very rarely but to give you a concrete example we recently had some research done on how the Internet could be used for child pornography. That actually literally explained how you could do it. I did not think it was in the national interest that that should be published. We made it available on restricted circulation to limited police officers and I thought that was the right thing to do. The third thing, occasionally, is commercial confidentiality.

  Q1121  Mr Newmark: I can understand the points you are making but generally expert advice that is given to ministers . . .

  Professor Wiles: Forgive me, that is a different question. You asked me initially about research and I am saying when we commission or carry out social research in the Home Office then that is published subject to what I have just said. Advice to ministers is quite different. We do not publish the content of our advice to ministers.

  Q1122  Chairman: Do you think you should?

  Professor Wiles: I think it is sensible to do what we do, which is to publish the underlying research on which that advice has drawn.

  Professor Sir Gordon Conway: In principle I think all our research is meant to be available. I would not guarantee it is all out there. We have a new research portal which is being geared up at the moment so that is where that research will be published. I do not agree that advice to ministers as such should be published because I think it changes the nature and the quality of what you write. There has to be within government some areas where you can speak very frankly in a way that if it got out more openly and picked up by the press it would be distorted and misinterpreted.

  Professor Kelly: There will always be some tension between the quality of something—whether it is not of high enough quality to publish—and political sensitivities or media sensitivities. I think a large part of what I have been doing with great help from the Civil Service team who work with me is to get routinely the presumption established that our research management database, the web portal to our research, that that is populated, that the material is there. It aids with transparency, peer review and it pushes the quality up for the writers if they know it is going to be accessible.

  Q1123  Mr Newmark: Specifically on the advice side, advice to ministers?

  Professor Kelly: I do not have anything to add to what Gordon said. I think it is a tricky, difficult issue.

  Q1124  Mr Newmark: You feel you could not be as open with some of what you would like to say.

  Professor Kelly: I think that a key activity for CSAs ought to be to attempt to separate out those aspects of the issue which can be debated within, say, a learned society. For example, debating regression to the mean in the Royal Statistical Society, it was easy enough because I had very sympathetic ministers to convince them that this was a group who would actually view regression to the mean as hugely sexy and what they wanted to talk about, rather than death on the road. Similarly the Royal Academy of Engineering was very, very keen on the technology of road user charging and were not looking to a newspaper headline. That is part of what the CSA has to help do to separate out those areas that can be put into a useful, transparent, open peer review area, and try to separate off other areas.

  Q1125  Margaret Moran: On advice to ministers you specifically referred to a research done on Internet child pornography. Would that advice be shared with other ministers in other relevant departments like DfES?

  Professor Wiles: Yes, it was. It was shared with other departments but its publication was restricted to officers and police forces.

  Q1126  Adam Afriyie: I am a relatively jolly person. I think that people's happiness should perhaps be the ultimate goal for politicians and their politics. Poor communication of risk can cause an enormous amount of stress and unhappiness for people, especially when it is misperceived or they are worrying about things which may or may not happen. Public consultation is the basis of this question and in particular I would argue that it may well be a cruel trick because it either raises the expectations of people taking part that something good may happen or it alerts them to risks that really have no relevance in their lives in the very long term. In your view what is the primary role of public consultation when it comes to evidence based policy creation? The alternatives might be: is it to shake government policy? Is it to inform the public? Is it to make the government aware of the public concerns?

  Professor Wiles: It is an interesting question and in a sense I was half guessing at that when I gave my example of the crime statistics. One of the reasons I gave that example is that I think that if we are not very careful people are left with an incorrect and overestimation of their risks. I think there is a very important balance we have to get right here. On the one hand you do want people to be sufficiently aware of the risks in order to take sensible precautions to manage those risks. I do not want to go around saying that there is no risk whatsoever of being a crime victim. That would be a silly and counter-productive thing to say because people do need to take precautions. What I do try to do—and I think it is important to try to do this—is to try to make sure that people understand that risk as much as possible, understand that it may vary from place to place and from people to people, and more to the point that as part of making that available we also make available the evidence we have on what you can do to mitigate the risk. For example—and I am glad to see the press have been very helpful on this—we have made very clear over a number of years in the Home Office that there are things that people can do to reduce the risk of household burglary and we have got good evidence on that. Therefore getting that message across that this is the risk and this is what you can do to mitigate and reduce that risk is a very important part of that process.

  Q1127  Adam Afriyie: In terms of public consultation what is the aim of it?

  Professor Wiles: First of all I think it would be arrogant and stupid for government to think that it knows everything and knows best. I think it is extremely important that we regularly test the assumptions that we are operating on and our perceptions against a wider public understanding and sometimes what happens of course is that you go out there and say, "This is the problem and this is what we propose" and people blow raspberries at you and tell you you have got it wrong. I have done that kind of thing myself, going round local communities, talking about crime rates and local communities saying, "Look, you've got it wrong; it's not what you're saying it is, it's something else". It is very important to have that dialogue because it is one of the checks against the evidence base you are using.

  Professor Sir Gordon Conway: I would agree with Paul. What works with consultation is that every answer you get has usually got something new in there in terms of at least a perspective or maybe some new information. That broadens the range of views that we can take into account.

  Professor Kelly: I have nothing useful to add to that.

  Chairman: We are moving onto just yourself, Paul. You are quite welcome, Gordon and Frank to leave at this point, but we are only going to be here for another five minutes and I am sure you will be fascinated by what Paul has to say and if you want to add a question you can do so.

  Q1128  Margaret Moran: I am sure that you are aware that the evidence we have had around the scientific basis for ID cards has been somewhat critical. Can you tell us what your involvement has actually been in the development and implementation of the policy? Why does Sir David King chair the Biometrics Assurance Group rather than you?

  Professor Wiles: First of all, what has my own role been and, I suppose more importantly, what has the role of a scientific adviser been in the development of ID cards? You are asking specifically about ID cards; I actually see the problem as slightly broader than that because ID cards is not the only Home Office area where the use of biometrics to manage identity is being used. It is also there in the e-borders programme; it is also there in the biometrically enabled passports. There is a broad range of things. What have I been doing on that? First of all we have an overall Home Office committee which covers the range of those different biometric identity management processes but they are in different parts of the Home Office. There is a technical sub-committee of that which I chair. There is a technical sub-committee in order to ensure that happens. What I have also done—and I referred to this earlier on—is to recruit and appoint a senior biometric adviser for the Home Office, Dr Marek Rejman-Greene, who is there precisely to ensure that there is scientific advice and we recruited Marek because of his previous experience at BT and particularly his involvement in the development of international standards and so on. I have made sure that additional advice is brought into the Department as these processes began to develop. We have, as you know—I think you were told this by my colleagues when they were before you—a biometric expert advisory group made up of people from within the Home Office and we also have the biometrics advisory group chaired by Sir David, as you have already said. Why does Sir David chair it rather than me chairing it? Because at the time that I felt it was necessary to have such an advisory group it was also clear that, although at the moment the first developments of biometrics identity management are happening in the Home Office, it was likely to spread to other departments in government as well. This is a new technology which I think is probably going to have wider application. It therefore seemed to me it would make more sense to have an advisory committee that was chaired by the Government's Chief Scientific Adviser so that it could act as a scientific advisory committee in the first instance for the Home Office development but then subsequently for development anywhere else in government. That was the reason why I asked Sir David to chair it and I am delighted so say he agreed.

  Q1129  Margaret Moran: You focussed on biometrics but obviously the issue of ID cards within the Home Office is much wider than that.

  Professor Wiles: Yes.

  Q1130  Margaret Moran: You said earlier, as I understood it, that you had halved the number of social researchers within the Department.

  Professor Wiles: Correct.

  Q1131  Margaret Moran: How does that impact on the social science in respect of ID cards? Surely it means, from the sound of it, you are neglecting that aspect of scientific policy altogether.

  Professor Wiles: No, I do not think I am neglecting it. We still have about 250 social researchers and statisticians in the Home Office. This was not a matter of reducing the numbers to the point where the work that was needed could not be done. It was a matter of balancing the portfolio skills, as it were. For example, when I arrived at the Home Office two things were not happening that are now happening. First of all there was no social research programme on immigration. Five years ago now I put that in place because I felt that was important. There was only one person having any interest in drugs research; we now have a drugs research team, so that was another re-balancing. We had a very, very tiny group of economists and we now have a slightly larger group of economists. Again I thought that was a necessary thing to do. The reason I referred to biometrics is because I do not have responsibility for ICT in the Department and of course if you are talking about ID cards there are I think two critical areas of dependency: one is the biometric technology and how well that does or does not work and the other is the IT platform on which that biometric technology will sit. I have been focussing on the biometrics side of that problem.

  Q1132  Margaret Moran: On the issue of the requirement for the ID card we have had a lot of evidence that there is a severe lack of clarity as to what ID cards are supposed to achieve and the extent that that poses a serious risk to the entire programme and indeed home security risks because of the way the proposals have been put together without any clarity about what they are expected to achieve. Are you satisfied that the scientific advice that is being provided is being taken into account in this whole programme?

  Professor Wiles: The brief answer is yes, but let me explain a little bit. First of all, the overall purpose of ID cards is of course a matter for you in Parliament and that was debated and put through the House. The bald purpose is there. The specific requirements for the development are of course precisely going to go out—and they are about to go out now—in terms of the start of the procurement process. We cannot possibly get into a procurement process for ID cards without being clear what we expect those ID cards to be able to do, so there will be specification in there. Have I been involved in that? Yes, I have, and so have my other colleagues. I keep stressing that it is not just me personally who is involved, it is other scientists in the Home Office and we have been involved in that. There are various groups and Sir David's group has also set up some sub-groups to work on particular issues of that to make sure those specifications are clear and will deliver the purposes for which we want ID cards.

  Q1133  Margaret Moran: Given that the objective has changed during this debate, if you accept that during the course of the debate the issues relate not just to the Home Office, are other scientific advisers in other parts of government also involved in informing the outcomes on the ID cards?

  Professor Wiles: You will forgive me, I am not going to comment on what was an implicit policy question there about the overall goals, but are there other scientific advisers involved? Certainly in terms of the Cabinet Office's responsibility for broad ICT platforms, yes that is happening. The other thing that has been going on—and it is important—is to try to make sure we understand the business cases and the potential business applications of identity management programmes across government. Clearly there is an important issue here about interoperability and whether we can ensure there is interoperability. My experience of that is that the most difficult problem—this is true both inside the Home Office and elsewhere in government—is not so much if you ask people "If you had ID cards, if you had this method of identify management now, what difference would it make to your business?" People tend to answer that in terms of their current business model. I think the more interesting question is: "Would it enable you to change your business model? Would it enable you to do something in a different way than you are doing it now?" That is where I think we have been working across government trying to get a greater degree of clarity.

  Q1134  Dr Iddon: We are doing three case studies. One is ID cards; the second one is the classification of drugs. Is the Home Office happy that the current classification of drugs is working for society?

  Professor Wiles: Can I just go back a little bit? Prior to the current legislation in this country we did not classify drugs into different categories, we simply banned drugs. Indeed, I think I am right in that more than half the EU countries still do that.

  Q1135  Chairman: That is not the question.

  Professor Wiles: I am answering the question, I assure you. We decided we wanted that classification and the question is, is the classification working? In a broad general sense yes, I think it is. I think there is broad agreement on the different risks at one end from the possession of a small amount of cannabis and on the other hand the supply of crack cocaine. I think there is broad agreement that those are clearly at opposite ends of a spectrum of harm and risk. I also think that generally speaking the classification system, since it has been in place, has provided a framework for those in the criminal justice system—the police, the judges or whatever—to implement the legislation. I think broadly it has done that. I think it has also broadly enabled most members of the public to understand the relative risks of these different drugs. I think broadly yes, it has. However, I am well aware—I read your exchanges with my colleagues from the Drugs Advisory Committee—that of course within that classification are some very difficult arguments about the relative rank order and the reason why you have those difficult questions—and Sir Michael, I know, made this point to you—is because we do not have a drugs classification system that has a single criterion running through it. If you had a single criterion then it might be easier to do that. We have a system that asks the Drugs Advisory Committee to take into account a number of different risks and those risks are not necessarily uniform in the way that they are hierarchically organised.

  Q1136  Dr Iddon: Sir Michael Rawlins and David Nutt (Chairman of the Technical Committee of the ACMD) told us that drugs are classified in that classification according to the risk to society and the risk to an individual approximately 50/50. I put it to them that psilocin and psilocybin, which are class A drugs, I have never seen them for sale on the street, I have never heard of anybody using them, I have never heard anybody dying from using either psilocin and psilocybin. If the Advisory Committee on the Misuse of Drugs is correct in its definition, why are psilocin and psilocybin in class A?

  Professor Wiles: I think, as they both discussed with you when they were here before you, once you have a classification system like this there is a problem of historical accretion, as it were, at which point decisions are made. I think the point that I know you questioned them on and it is difficult, is of course that the evidence base is changing. I think what you are really raising is: should it be the case that we go back to zero and re-do at some point in time as the evidence changes? That is not the way the Committee has operated; the Committee has tended to operated as new problems emerge, as significant new evidence emerges. It has never gone back and, as it were, re-done the whole classification from base zero.

  Q1137  Dr Iddon: Do you attend meetings with the Advisory Council on the Misuse of Drugs?

  Professor Wiles: No, I do not and I should not do so. It is an independent scientific advisory committee.

  Q1138  Chairman: In terms of the re-classification, David Nutt and Colin Blakemore have actually produced a complete new classification. Why has that not been adopted?

  Professor Wiles: I assume you are referring to the unpublished Lancet paper which I have also read and I know you have seen. I think, as Professor Nutt explained to you, that is increasingly the basis on which the technical sub-committee of the advisory committee on drugs is operating and which of course Professor Nutt chairs. We do not have time, which is a shame, because actually there are some interesting issues even within that paper.

  Q1139  Chairman: Paul, we would be very interested in actually getting a response to that particular question as to why in fact Professor Nutt's work has not been adopted by the Home Office.

  Professor Wiles: Sorry, I think what I said was it is increasingly the basis on which Professor Nutt is operating as the head of the technical group on that committee.
