Correlations between the physical and social sciences

This is probably the most bizarre book I have received for review (so far).  Its title is wide-ranging: Correlations Between the Physical and Social Sciences.  Its cover is enticing: a picture of the young Albert Einstein. Its purpose is wide:

The thesis of this monograph is that societies in general are governed by objective laws that have their roots in human nature. The task of the social scientist is to discover and explore those laws (…) Null hypotheses and alternative rival hypotheses developed by social scientists must eclectically correlated to mathematical formulae or the laws of physics in order to advance non-speculative, unbiased knowledge.” V.J. Belfiglio (p.x)

So the thesis advanced in Correlations Between the Physical and Social Sciences by Valentine Belfiglio is that social problems can be represented in terms of physical laws. The 41 pages book pushes this argument through four cases studies.

The first case study relates marital assimilation of minority groups into dominate core cultures with Graham’s Law for the diffusion of gases. The second case study relates the mutual hostility of political leaders with the Mirror Equation employed in basic geometric optics. The third case study relates the duration of major American military conflicts to the formulae for empirical and subjective probabilities. The fourth case study relates the radioactive decay formula for radioactive substances to the rate of decline of several extinct empires” V.J. Belfiglio (p.xi)

As the author himself recognises, “the four case studies in this monograph do not provide definitive answers.” My opinion is that they do not provide answers at all! Indeed, the first chapter contains two 2×2 tables about the endogamous preferences of Mexican and Italian inhabitants of Dallas, Texas. A chi-square test concludes that Mexicans prefer endogamy and that Italians do not. Although Graham’s Law is re-expressed there as “marital assimilation being inversely proportional to the square root of the population densities” (p.3), there is no result based on the data supporting this law. The second chapter is trying to “explore the mutuality of hostility between the Bush and Ahmandinejad (sic) administrations. Spearman’s Rho correlation coefficient” (p.11) is used and found to demonstrate “a perfect positive correlation” (p.12), although the data is quantitative (intensity of hostility between 1 and 9) and not paired. (The study simply shows that the empirical cdfs of the hostility values for both sides are approximately the same, Spearman’s rho test being inappropriate there.) The connection with optics is at best tenuous. Chapter 3 centres on a table for the durations of major American (meaning US) military conflicts. A mere observation is that the US “has been engaged in major wars 56.5 percent of the time between 1775-2010.” (p.24) but Valentine Belfiglio turns this into “empirical probability” (i.e the frequency of wars), a “subjective probability” (i.e. the average number of years of peace between wars), and the “number of possible interaction channels” (i.e. a combination number) as a way to link American foreign policy with probability theory. Again, the connection is non-existent. The fourth and final chapter is about the “correlation between the decay of radioactive substances and the rate of decline of empires.” (p.31) The data is made of the duration of seven empires, associated with estimates of their half-life. The paper concludes on “a perfect negative correlation between the half-lives of empires and their rates of decline” (p.35), which is not very surprising when considering that one is a monotonic function of the other…

I conclude with the words of Henry Wadsworth Longfellow: “Sometimes we may learn more from a man’s errors, than from his virtues”.” V.J. Belfiglio (p.40)

There is therefore not much to discuss about this book: it does not go beyond stating the obvious, while the connection between the observed social phenomena and generic physical laws remains at the level of a literary ellipse, not of a scientific demonstration. I am deeply puzzled at why a publisher would want to publish this… Any review of the material should have shown the author was out of his depth—his speciality at Texas Woman’s University is Government—in this particular endeavour of proving that “mathematical formulae and the law of physics can take scholars further in deriving conclusions from sets of assumptions than can inferential statistics” (back-cover).
