The Negative Flynn Effect: A Systematic Literature Review

Edward Dutton, Dimitri van der Lindenb, and Richard Lynn, Science Direct, October 20, 2016

Abstract

The Flynn Effect (rising performance on intelligence tests in the general population over time) is now an established phenomenon in many developed and less developed countries. Recently, evidence has begun to amass that the Flynn Effect has gone into reverse; the so-called ‘Negative Flynn Effect.’ In this study, we present a systematic literature review, conducted in order to discover in precisely how many countries this reverse phenomenon has been uncovered. Using strict criteria regarding quality of the sample and the study, we found nine studies reporting negative Flynn Effects in seven countries. We also discuss several possible explanations for the negative Flynn Effect as an attempt to understand its most probable causes.
