It is easy for us to believe that as a society we are getting
smarter, at least as measured by IQ tests. This supposed
improvement, the Flynn Effect, suggests that each generation is
brighter than the last. If this improvement in intelligence is real
we should all be much, much brighter than the Victorians. However,
the researchers of this ground-breaking study find the reverse to
be true- the Victorians were cleverer than us! IQ tests may be
effective at picking out the brightest, but they are not reliable
benchmarks of performance over more than a century. Historical
Variance records the exploration of the Flyyn effect hypothesis,
which included the use of high-quality instruments to measure
simple reaction times (a recognised predictor of intelligence) in a
meta-analytic study. The conclusions are very sobering: far from
speeding up, we are slowing down. A decline in general intelligence
(a loss equivalent to about 14 IQ points) since Victorian times may
have resulted from the presence of dysgenic fertility. These
findings, as detailed in Historical Variance, strongly indicate
that the Victorians were substantially cleverer than we are
today...
