Book Review | Innumeracy: Mathematical Illiteracy and Its Consequences

'Innumeracy' is the mathematical equivalent of an adrenalin-filled rollercoaster ride. This book is a critical-faculty-sharpener of sorts.

John Allen Paulos‘ decision to write Innumeracy was largely a result of the anger and provocation he felt as he witnessed the widespread apathy toward numbers and probability.

As a society that is so dependent on mathematics, Paulos feels that we disregard the importance that should be accorded to the subject. Some might say that mathematics is not about numbers, but the hard truth is, it ultimately is about numbers.

Innumeracy: An inability to deal comfortably with the fundamental notions of number and chance.

A part of his angst stems from his observations that mathematics often gets to be looked down upon as an esoteric science with minor or no relevance to the daily routines.

Worse still, innumerates (shorthand for mathematical laggards) tend to flaunt their lack of mathematical prowess and this further irks the author.

Innumeracy is a significant malaise in its own but what compounds this inadequacy further is our ungrounded and often unshakable belief in dubious domains such as astrology, tarot cards, newspaper psychics, sports and medical claims etc.

A more debilitating situation arises when many educated individuals fall for the spurious appeals of these Pseudosciences. Astrology is called a pseudoscience because of its abject inability to withstand the tests of empirical scrutiny, thus, failing to match up to Science.

According to Paulos, innumeracy is the most potent reason behind the rampant flourish of pseudosciences. And, the blame for innumeracy turning into a sort-of-pandemic lies squarely with our educational systems.

When a child needs to be taught how to calculate estimates to 3 decimal places, he’s guided to take a short-cut and round off numbers instead, laments Paulos.

John Allen Paulos is like an expert ghostbuster who blows to bits many widely-cherished pseudo-scientific theories in the book. However, his galvanizing efforts won’t bear fruition unless society at large decides to turn into a mass of informed skeptics.

It’s simple – the business of baseless doctrines and theories thrives on people’s ignorance.

Only a progressive enlightenment could mitigate the blind beliefs people have in the pseudosciences and in people who propagate them. Paulos’ book is a small step in that direction but largely, the step is for the society to take.

Paulos also takes a cue from Daryll Huff and exposes the widespread statistical chicanery. Unlike Huff, Paulos doesn’t zero in on a particular industry or domain, however, he does enlighten the readers to various statistical pitfalls.

In a stinging recapitulation of what is wrong with Statistics,

When Statistics are presented so nakedly, without any information on sample size and composition, methodological protocols, confidence intervals, significance levels, etc., about all we can do is shrug or, if sufficiently intrigued, try to determine the context on our own.

Paulos deserves acclaim for writing a book so central to our irreducibly probabilistic lives. His use of witty anecdotes in conjunction with his hand-picked mathematical problems works to great effect in imparting the message. The idea is to motivate not to inhibit.

Finally, if you also happen to share an invariable apathy toward mathematics, then, Innumeracy is highly recommended for you. This little book would spur you on and reinvigorate your romance for Maths.
