{{cquote|In many areas [[Phenotype|phenotypic]] intelligence has been increasing (the [[Flynn Effect|Flynn Effect]]) while [[Genotype|genotypic]] intelligence is decreasing due to the negative association between intelligence and that which is known as "[[Dysgenics|dysgenic]] fertility". Gains of as much as 7.5 IQ points in phenotypic intelligence are much greater than the 0.43 IQ points per generation in the world-wide genotypic IQ that had been estimated for the period 1950-2000. The situation in the industrially developed world appears to follow the lead of the United States and a handful of other developed nations in so far as the phenotypic IQ has been increasing at a greater rate as a result of environmental improvements.

As far as dysgenic fertility (people with lower intelligence having more children) and its effect on population's intelligence, the abstract for journal article ''IQ and fertility: A cross-national study'' published in the journal Intelligence states:
{{Cquote|Many studies have found a small to moderate negative correlation between IQ and fertility rates. However, these studies have been limited to the United States and some European countries. The present study was a between-nation study using national IQ scores and national fertility rates. There were strong negative correlations found between national IQ and three national indicators of fertility.<ref>Abstract for journal article ''Intelligence'', [https://www.sciencedirect.com/science/article/abs/pii/S0160289607000244#:~:text=Numerous%20studies%20have%20confirmed%20that,with%20higher%20levels%20of%20IQ.

In Norway, Sweden, Denmark, Great Britain and Australia phenotypic intelligence has stabilized and now is declining.<ref>[https://www.academia.edu/1203173/The_Rise_and_Fall_of_the_World_1_ ''The Rise and Fall of the World's IQ''] by Thomas Hally</ref>}}
