  • Chapter 10 summarizes future possibilities. In this review, we focus on chapters 2—4, which explore the 3 downoad which the authors claim big data will bring to the scientific table and which we believe will be of most interest and most concern to readers of the Journal. The authors argue that new technologies will allow data scientists to passively collect, store, and analyze much more data in real time.


    However, the authors seem to misunderstand random sampling. As far as we can understand with regard to this passage, the authors are confusing issues of precision and validity: A simple random sample of the 11 years' worth of sumo bouts might have had less power to reveal the finding than an analysis of all bouts, but it is nonsense to suggest that the same pattern would not have emerged in a simple random sample of the bouts.

    Google Flu Trends Google, Inc. If we were interested in a disease that was more concentrated among persons without access to computers, would Google searches work as well? Similar criticisms can be made of the authors' claim that when the data is [sic] collected devolution while people do what they normally do anyway, the old biases associated with sampling … disappear.

    We can now collect information that we couldn't before, be it relationships revealed via mobile phone calls or sentiments unveiled through tweets 1p. The idea that information revealed through tweets is free from bias is simply risible: Twitter Twitter Inc. Moreover, public health science is frequently faced with finite resources: It is far from clear that it is in the interests of public health to devote resources to for example expensive assays in a hransform large sample of individuals when a simple random sample will provide the same point estimate and negligibly worse precision.

    A meta-analysis of 10 studies with the same measurement error bias will be more precise, but no more valid, than any single one of those studies. At the same time, the increased precision will offer increased but false confidence in those fundamentally flawed results.

    To expand daya this: Whether a larger but messier data set is preferable to a smaller but less messy data set is a substantive question on which we believe epidemiologists should take a consequentialist thzt 5 : The data set to be preferred is the one that will yield an answer that will in turn lead to the greatest improvement in human health. It is far from obvious that more is always better—indeed, more may sometimes be less.

    Thus, the authors argue, if we believe that E causes D, but E is not associated with D in x correlational analysis of big data, we can safely conclude that E does not cause D. Of course, this is wrong: Confounding bias among other types of bias can just as easily erase a true causal effect as create a spurious one.

    Throughout this chapter, the authors offer examples of how estimation of correlations in big data has yielded insights leading to improved practices—for instance, predicting infection in premature infants in intensive care 24 hours before overt symptoms appear 6 or predicting who will be readmitted to the hospital after discharge 1p. The authors are right that such predictive analyses can play an important role in improving health, even without establishing causality; but at the same time, they fail to appreciate the central role of understanding causality in improving public health, and too often conflate predictive and etiologic inference.

    Accessible in style, the book provides: A synoptic overview of big data, open data and data infrastructures An introduction to thinking conceptually about data, data infrastructures, data analytics and data markets Acritical discussion of the technical shortcomings and the social, political and ethical consequences of the data revolution An.

London: Murray, 2 José Van Dijk. Ultimately, Big Data: A Revolution That Will Transform How We Live, Work and Think is for forward thinkers who crave and fear new data techniques that could spur profits and understanding, but who also recognize the dangers that Big Data might pose to privacy and individual liberty.

    Their phrasing raises the question of the x goal of the exercise. If our goal is merely to identify patients likely to go into remission in the future, then the authors are correct; but if our goal is to help additional people who are suffering with cancer go into remission, then it matters a great deal whether it is a combination of orange juice and aspirin that caused the remissions or rather some other, associated thatt. If it is the latter, obviously, a recommendation to drink more orange juice and take more aspirin is unlikely to have an effect on individual or population health.

    We recall early perhaps apocryphal notions that scurvy was associated with not being on land, and therefore sailors were treated by being buried neck-deep in dirt, to no avail. Chapters 5—10 do a good and highly readable job of giving examples of how big-data approaches may transform both business and health in the coming decades, as well as the potential dangers of the datafication of society.

    However, the perspective of this book offhandedly discounts decades of work in numerous fields with little justification or explanation, in a way rife with misconceptions.

    Yet it seems equally clear that the perspectives offered in this book would benefit from a firmer tdansform in existing scientific approaches and perspectives, and thus at present they may have relatively little utility for the practicing epidemiologist. Google Scholar. Google Preview.
