Book Review: The Escape from Hunger and Premature Death, 1700-2100 by Robert Fogel

This book presents good arguments that hunger was a major cause of health problems everywhere a century ago, and that the effects last long enough that even the richest countries are still suffering from problems caused by hunger. His arguments imply that experts persistently underestimate improvements in life expectancy, and even with little improvement in medical technology life expectancy will improve a good deal because people born today have much better nutrition than today’s elderly had as children.

This goes a long way toward explaining the Flynn effect (even though the book doesn’t mention Flynn or IQ). It correctly implies the biggest intelligence increase should be seen at the low end of the IQ range, unlike a number of other interesting theories I’ve come across.

Another peculiar fact that the book helps to explain is the high frequency with which the tallest presidential candidate wins. Fogel’s arguments that height has been one of the best indicators of health/wealth suggest that this is not an arbitrary criterion (although it is probably a selfish I-want-to-ally-with-a-winner strategy that may be obsolete).

The book is mostly non-idealogical, but occasionally has some good political arguments (page 42):

government transfers were incapable of solving the problems of beggary
and homelessness during the eighteenth and much of the nineteenth centuries,
because the root cause of the problems was chronic malnutrition. … At
the end of the eighteenth century British agriculture, even when supplemented
by imports, was simply not productive enough to provide more than 80 percent
of the potential labor force with enough calories to sustain regular manual
labor.

(page 106):

Readers may be surprised that I have not emphasized the extension of health insurance policies to the 15 percent of the population not currently insured. The flap over insurance has more to do with taxation than with health services. … Most proposals for extending health insurance involve taxing their wages for services they already receive.
