Though other studies have examined relationships between whole grain intake and mortality, this paper is the first to look at data compiled on individuals who already have diabetes, according to Lu Qi, an assistant professor in the department of nutrition at HSPH who co-authored the study...
...author wants to draw the wrong conclusion from the fact that simplified models get things wrong (even dramatically wrong). No one denies that we need to better understand and communicate the limitations of data, that it is crucial to guard against unjustified trust in our preferred models (perhaps the author forgets that before the crisis, there were plenty of critics of the efficient market hypothesis who were using data and simulation to predict pathological behavior in asset markets). But a data-driven, formal approach to making policy decisions is quite frankly the best we can do and therefore essential...
Models, by design, are simplifications with clearly false assumptions. But the success of models lies in their ability to rationalize and often rightly predict the behavior of more complex real systems. Confused applications of the uncertainty principle notwithstanding, the author’s disdain for the “data-heavy, model-driven graduate student” is unjustified. Perhaps in his next piece, Mr. Barbieri can suggest an alternative to restrictive modeling in understanding and predicting phenomena...
...imperfectly informed as the experts at the Volcanic Ash Advisory Center might be, their judgments on the basis of data and computer simulation are presumably more useful than the alternative: the intuitions of the CEO of Air-or-Bust, or perhaps, Mr. Barbieri, on when it’s safe...
...study, published in The American Heart Association’s Circulation journal on monday, analyzed data from 7,822 U.S. female nurses with type 2 diabetes and found that the group of individuals with the highest level of grain intake displayed a 16 to 31 percent lower mortality rate than the group at the lowest level...
