Police Reform and Social Responsibility Bill

Debate between Lord Wasserman and Lord Harris of Haringey

Wednesday 29th June 2011 Lords Chamber

[Lord Harris of Haringey]

I am sure that if the noble Lord were to move to Lancashire, that could be arranged. Although I think that that would be an interesting and enticing prospect, and no doubt incredibly scary for the chief constable of Kent, I wonder whether the damascene conversion that the noble Lord, Lord Howard, has described to us several times would not have been made easier had his original proposals for police authorities been subjected to a series of pilots. He could then perhaps have discovered at an earlier point that the model he initially favoured was flawed.

[Lord Wasserman]

My Lords, as a former professional social scientist I welcome the enthusiasm in this House for pilot studies. However, like so much else in life, there is a right place for pilots and a wrong place. I am afraid that the circumstances we are discussing are very much the wrong place for pilots. I hope that your Lordships will allow me to explain why I say this and to do so by reference to the findings of academic experts.

The use of pilots in political or social research is discussed at some length in a book which I commend to your Lordships which can be found in the Library entitled, Research Methods in Politics. The book begins by pointing out that,

“there are times when … a trial run or pilot has considerable advantages. In particular, to test the data collection instruments such as the questionnaire and the sample design”.

Indeed, the Home Secretary herself is a great believer in the use of pilots in the appropriate context. In a speech that she gave about two months ago—I am sure that some noble Lords will have seen it—she announced not one but two new pilots. The first was related to her wish to allow the police to charge more offences themselves. She said:

“We will pilot doubling the number of charges transferred to police officers”.

She added that if the pilot was successful and the scheme was rolled out fully, it could save up to,

“40,000 hours of police officer time”.

In the same speech she announced that the Home Office was working with ACPO to ensure that best practice on domestic abuse processes was effectively shared by all forces. She said that the next step was to pilot these new proposals, and that if the pilots were successful they would be rolled out across the country.

However, the circumstances we are discussing are nothing like those mentioned by the Home Secretary or the academic experts. They are classic examples of circumstances where pilots are not appropriate and lead only to a waste of time and money. According to the experts, the classic example of the inappropriate use of pilots in a political or social context—that is what we are talking about—is to compare jurisdictions over time and/or space, a point made by the noble Lord, Lord Howard. The experts state:

“There are a number of reasons why comparisons can turn out to be meaningless. Most famously, the condition known as ‘too many variables, not enough cases’. This is a reason why experimental control is rarely an option in political science. Additionally, comparative research is affected by two manifestations of the so-called travelling problem: that is, neither theoretical concepts nor empirical measurements are consistent across temporal and/or spatial settings. In other words, they do not ‘travel’. This diminishes the possibility of controlling for the effect of variables other than those of primary interest”.

Translating the jargon, what these experts are trying to say is that it is impossible to make meaningful comparisons between different times and places because there are simply too many factors in play. However, your Lordships do not need academic experts to tell you that the sort of governance arrangements such as those that we are discussing cannot be subject to scientific evaluation.

[Lord Wasserman]

This is not about using a particular bit of legislation in particular areas and comparing them in an academic research environment. The examples that I am giving noble Lords are of real change achieved by real chiefs with real mayors in real cities.

[Lord Harris of Haringey]

The core of the noble Lord’s argument against pilots is that he is cautioning us against the spatial differences between different parts of this country and the temporal differences—because this is a different time. Now he is saying that you can draw from experience 3,000-plus miles away, which is quite a big spatial difference, under a different legal system and so on. The temporal difference is that the improvement under Mayor Giuliani happened a number of years ago. I am not quite sure where this argument is taking your Lordships.

[Lord Soley]

In a circle.
