The Delphi Method
Here's a another method for trying to see into the future by the systematic pooling of insights and ideas from a group of experts. Developed by RAND in the 1950s. A good discussion is contained in this article on the future of netcrime. The idea, in essence, is to have structured questioning, anonymous responses (to let information and opinion flow freely), and a system of iteration and feedback. As Sheridan Morris of the UK Home Office puts it in the paper,
This is an interesting idea...and not unlike some notions from physics. Even if complete and specific prediction is not possible, qualitative prediction may be possible.
of course, one might compare this with the various futures markets that pool information to make predictions, apparently with considerable accuracy.
...a Delphi approach may also be combined with other futures techniques such as the use of scenarios. The Delphi technique may be found in areas where there is an absence of sufficient data and/or an incomplete theory on cause and effect in regard to the area under study. Sitting between knowledge and speculation, the outcome of the panel may be considered informed judgement.

The dismal science
You must have a chapter on the appalling science of economics, and how it has failed forever to make decent predictions. A good starting place is this post from Leiter Reports. He's a lawyer or philosopher and has a lot to say, with many links, to deep criticisms of the field, its scientific status, and its ability or inability to make predictions. A couple selections:
and
As fate would have it, an economist has been posting on the topic du jour--the scientific status of economics: see Tyler Cowen here and here. Professor Cowen's perspective on this question (rather typical of economists, I fear) is well-expressed by a colleague of mine:
"I guess the reason that I think economics is a science is that empirical testing is a huge part of economics. I.e., if economics were only about the mathematical models, without falsifiable claims, I would agree it's not scientific. But economics makes falsifiable claims all the time and tests them frequently. And some are confirmed, repeatedly, and they become accepted wisdom. Others are falsified, and they fall by the wayside. Isn't that what science is all about?"
This isn't, however, what "science is all about" on any plausible account. Pest control, for example, would be a science on this account (exterminators operate with evidentiary hypotheses ["ah-ah, tell-tale rat droppings!"], which they test ["since it's rats, we'll lay this kind of poison"], and which are sometimes falsified ["well, I'll be damned, it turns out it's not rats, but field mice"]), which doesn't seem the right conclusion. And lots of paradigmatic scientific propositions ("there are black holes," "there are quantum singularities") wouldn't be "scientific", because they aren't falsifiable (I owe the examples to Larry Laudan). Some philosophers of science go further, and argue that no claims are falsifiable (on evidentiary or logical grounds) because of the underdetermination of theory by evidence (the "Duhem-Quine" thesis as it is known) (Laudan has interesting arguments against this point--a nice presentation is in the so-titled chapter on undeterdetermination in his Science and Relativism [Chicago, 1990], which is still the best introduction to the subject I've read.)
and
Often, modern economic analyses of law turn out to be remarkably indifferent to the empirical facts. Even predictions generated from the Coase Theorem--the cornerstone of modern law-and-economics--have been empirically falsified! (See Robert Ellickson, Order Without Law: How Neighbors Settle Disputes (Cambridge, Mass: Harvard University Press, 1991)). The Coase Theorem says that "if there are no transaction costs to impede bargaining, legal rights will be allocated efficiently through private exchanges, regardless of the underlying rule of law." Robert Cooter, "Against Legal Centrism," California Law Review 81 (1993), pp. 417-429, at 419 n. 6. As Cooter explains: “Liability rules can be structured in different ways. With cattle, for example, the law can make owners of cows responsible for fencing them in ("closed range") or non-owners responsible for fencing them out ("open range"). Coase reasoned that owners will fence cows in or non-owners will fence them out, whichever is cheaper, regardless of the law. . ..Ranchers need only bargain together. . ..The law simply tilts bargaining against the party who is legally liable. Thus the law affects who pays for the fence ("distribution prediction"), but not its extent or location ("efficency prediction"). Id. at 419. What Ellickson found is that neither prediction was borne out among real ranchers that Ellickson studied in Northern California. Cooter notes: "Not only does the Coase Theorem fare poorly in empirical tests, but theorists who have tried to prove it mathematically usually conclude that it is either false or a tautology." Id. at 422. None of this, remarkably, has undermined its importance for the "science" of economics!
Philosophers, too, have recently launched a devastating attack on the scientific and cognitive credentials of economics, starting from the observation that, "[E]conomic theory [is] one of the more dismal empirical failures in the history of science" (John Dupre). This is widely conceded about the laughably unsuccessful predictions of macroeconomics, but it is only somewhat less true of microeconomics, which "has made no advances in the management of economic processes since its current formalism was first elaborated in the nineteenth century" (Alexander Rosenberg, "If Economics Isn't Science, What Is It?" reprinted in D. Hausman (ed.), The Philosophy of Economics: An Anthology, 2nd ed. (Cambridge: Cambridge University Press, 1994), p. 377. Cited hereafter in the text by page number only as Rosenberg II. See also, Wassily Leontief, "Input-Output Economics," Scientific American 185 (1951), pp. 15-21.) This last point bears elaboration.

Limits to prediction
A paper here by David Wolpert on the idea of "inference machines" -- any physical machine that would make predictions of the future -- and the inherent limits to their abilities. The abstract:
We show that physical devices that perform observation, prediction, or recollection share a mathematical structure. We call devices with that structure ``inference devices''. We present existence and impossibility results for inference devices. These results hold independent of the precise physical laws of our universe. The impossibility results establish that Laplace was wrong to claim that even in a classical, non-chaotic universe the future can be unerringly predicted. Alternatively, they can be viewed as a non-quantum mechanical ``uncertainty principle''. The mathematics of inference devices is related to the theory of Turing Machines (TM's), e.g., some impossibility results for inference devices are related to the Halting theorem for TM's. Furthermore, one can define an analog of Universal TM's (UTM's) for inference devices, which we call ``strong inference devices''. We use strong inference devices to define the ``inference complexity'' of an inference task, which is analogous to the Kolmogorov complexity of a string. A task-independent bound is derived on the difference in inference complexity of an inference task performed with two different inference devices. This is analogous to the ``encoding'' bound on the difference in Kolmogorov complexity of a string between two UTM's. However whereas the Kolmogorov complexity of a string is arbitrary up to specification of the UTM, there is no such arbitrariness in the inference complexity of an inference task. We informally discuss philosophical implications of these results, e.g., for whether the universe ``is'' a TM. We also derive some graph-theoretic properties governing sets of multiple inference devices. Next we extend the framework to address physical devices used for control, and then to address probabilistic inference.
Predicting crime
Some information in predicting crime. There are a several interesting areas:
1) Predicting changes in overall crime rates (say within a nation or community). The two major factors useful for doing so are either demographic or economic, as indicated in this article from the Canadian Justice Department. The key demographic factor is the number of male between 15-25; crime rates also correlate with economic conditions (although there seems to be sme ambiguity as to whether the link is positive or negative, which makes me wonder what is really known...some argue more wealth leads to more crime ---there's more to steal -- while others say more wealth makes for less crime -- fewer people need to steal).
2) Predicting slightly more specific changes by looking for meaningful patterns. For example, there are a number of well documented seasonal cycles, as described at Crimepsychblog. For example, I quote:
3) Predicting more specific changes by treating crime in an epidemiological kind of way, realising that it has correlations in space and time. See, for example, the work of Kate Bowers, Shane Johnson and Ken Pease. Or work showing that one burglary in an area increases the chance of another crime within a few hundred yards for several months. For example:
There is, of course, also the notable work of Glaeser, Sacerdote and Scheinkman, showing that crime has significant spatial fluctuations, more than can be accounted for by economic fluctuations:
In another paper, Glaeser and Sacerdote note that crime is much more pronounced in larger than in smaller cities, although they don't go a long way to explaining why. I wonder: could this simply reflect another scaling law like those seen in many other variables such as energy consumed, the average speed of walking, etc? [I can't find the link to this at the moment, but it's the work, I think, of Geoffrey West, Luis Bettencourt and others].
A few more random observations on crime patterns:
* Another link from Crimepsychblog
to work showing that the sites where crimes are committed are not equally. Rather, they tend to be power law distributed in terms of the likelihood of crime:
The paper to see is Understanding Risky Facilities published by the US Department of Justice.
* Another interesting idea is that of Hot Products -- particular products that, in a physics sense, act as catalysts for crime. Think mobile phones or other expensive electronics stuff. A report from the UK Home Office gives more detail:

2) Predicting slightly more specific changes by looking for meaningful patterns. For example, there are a number of well documented seasonal cycles, as described at Crimepsychblog. For example, I quote:
Peaks in the summer months and troughs in the winter months: […Two sexual] offences follow very similar seasonal patterns to each other with a large peak in July, when indecent assault on a female is 21 per cent above trend and rape of a female is 14 per cent above trend. Theft of a pedal cycle has a very clear seasonal pattern; peaks start in May and continue to reach 29 per cent above trend in September… Arson, unlike other criminal damage offences, shows rises in summer months…
Peaks in the winter and troughs in the summer months: Just four crime types display seasonal peaks in the winter and falls in the summer. These are
all property crimes. Domestic burglary peaks to 11 per cent above trend in January. … It is important to note that domestic burglary has an opposite seasonal pattern to nondomestic burglary.
3) Predicting more specific changes by treating crime in an epidemiological kind of way, realising that it has correlations in space and time. See, for example, the work of Kate Bowers, Shane Johnson and Ken Pease. Or work showing that one burglary in an area increases the chance of another crime within a few hundred yards for several months. For example:
Crime Patterns of Risk: A Cross National Assessment
of Residential Burglary Victimization
Shane D. Johnson Æ Wim Bernasco Æ Kate J. Bowers Æ Henk Elffers Æ
Jerry Ratcliffe Æ George Rengert Æ Michael Townsley
Springer Science+Business Media, LLC 2007
Abstract Using epidemiological techniques for testing disease contagion, it has recently been found that in the wake of a residential burglary, the risk to nearby homes is temporarily elevated. This paper demonstrates the ubiquity of this phenomenon by analyzing space–time patterns of burglary in 10 areas, located in five different countries. While the precise patterns vary, for all areas, houses within 200 m of a burgled home were at an elevated risk of burglary for a period of at least two weeks. For three of the five countries, differences in these patterns may partly be explained by simple differences in target density. The findings inform theories of crime concentration and offender targeting strategies, and have implications for crime forecasting and crime reduction more generally.
There is, of course, also the notable work of Glaeser, Sacerdote and Scheinkman, showing that crime has significant spatial fluctuations, more than can be accounted for by economic fluctuations:
The high degree of variance of crime rates across space (and across time) is one of the oldest puzzles in the social sciences (see Quetelet (1835)). Our empirical work strongly suggests that this variance is not the result of observed or unobserved geographic attributes. This paper presents a model where social interactions create enough covariance across individuals to explain the high cross- city variance of crime rates. This model provides a natural index of social interactions which can compare the degree of social interaction across crimes, across geographic 1units and across time. Our index gives similar results for different data samples and suggests that the amount of social interactions are highest in petty crimes (such as larceny and auto theft), moderate in more serious crimes (assault, burglary and robbery) and almost negligible in murder and rape. The index of social interactions is also applied to non-criminal choices and we find that there is substantial interaction in schooling choice.
In another paper, Glaeser and Sacerdote note that crime is much more pronounced in larger than in smaller cities, although they don't go a long way to explaining why. I wonder: could this simply reflect another scaling law like those seen in many other variables such as energy consumed, the average speed of walking, etc? [I can't find the link to this at the moment, but it's the work, I think, of Geoffrey West, Luis Bettencourt and others].
A few more random observations on crime patterns:
* Another link from Crimepsychblog
to work showing that the sites where crimes are committed are not equally. Rather, they tend to be power law distributed in terms of the likelihood of crime:
This one points out the maths of crime: it is almost always a small fraction of any kind of place (convenience store, bar, etc) that accounts for most of the crimes. Which is maybe not so surprising as most everything works this way. But this is undoubtedly useful for policy, as in treating the spread of diseases.
The paper to see is Understanding Risky Facilities published by the US Department of Justice.
* Another interesting idea is that of Hot Products -- particular products that, in a physics sense, act as catalysts for crime. Think mobile phones or other expensive electronics stuff. A report from the UK Home Office gives more detail:
The mobile phone
A good example of a hot product is the mobile phone. Expansion of the mobile phone market has been rapid. The targeting of mobile phones is already a factor in increasing rates of street robbery. As mobile phone handsets incorporate internet technology mobile phone crime is likely to continue and increase. The ‘no-contract’ mobile phones are particularly attractive to criminals because: they allow greater anonymity for callers; there are loopholes in the ‘pay as you go’ mobile phone schemes that enable knowledgeable users to switch to other networks and avoid payment; the vouchers used to pay for calls can also be targeted for theft; vouchers are easy to reproduce; and, criminals have reprogrammed ‘prepaid’ mobile phones to obtain free calls (reported in Association of British Insurers 2000: 14). http://www.insurance.org.uk/ResearchInfo/
Examples of future hot products include (Association of British Insurers 2000)
The launch of Digital Television and the switch off of analogue transmissions may spark a crime epidemic in the rush to replace obsolete televisions. However, the offer of set-top boxes free of charge is likely to reduce their attractiveness to thieves.
Portable Digital Virtual Disc (DVD) players are now available weighing 900 grams and costing up to £1000.
