The reproduction of intelligence
TLDR
The relationship between fertility and education has been described consistently in most countries of the world, but less is known about the relationship between intelligence and reproductive outcomes as discussed by the authors, and also the paths through which intelligence influences reproductive outcomes are uncertain.About:

One Century of Global IQ Gains: A Formal Meta-Analysis of the Flynn Effect (1909–2013)
Jakob Pietschnig,Martin Voracek +1 more
TL;DR: Findings include that IQ gains vary according to domain, are stronger for adults than children, and have decreased in more recent decades, while factors associated with life history speed seem mainly responsible for the Flynn effect’s general trajectory.
Journal ArticleDOI
Is the Flynn effect on g?: A meta-analysis
TL;DR: A psychometric meta-analysis on all studies with seven or more subtests reporting correlations between g loadings and standardized score gains was carried out, based on 5 papers, yielding 11 data points (total N = 16,663) as discussed by the authors.

Assortative mating and differential fertility by phenotype and genotype across the 20th century
Dalton Conley,Thomas Laidley,Daniel W. Belsky,Jason M. Fletcher,Jason D. Boardman,Benjamin W. Domingue +5 more
TL;DR: Changing patterns of the number of children ever born by phenotype are not matched by shifts in genotype–fertility relationships over time and trends provide no evidence that social sorting is becoming increasingly genetic in nature or that dysgenic dynamics have accelerated.

Cognitive Capitalism: Human Capital and the Wellbeing of Nations
TL;DR: Rindermann as discussed by the authors established a new model: the emergence of a burgher-civic world, supported by long-term background factors, furthered education and thinking, resulting in past and present cognitive capital and wealth differences.

Massive IQ gains in 14 nations: What IQ tests really measure.
TL;DR: In this article, the authors show that IQ tests do not measure intelligence but rather a correlate with a weak causal link to intelligence, which can explain differential trends on various mental tests, such as the combination of IQ gains and Scholastic Aptitude Test losses in the United States.
Journal ArticleDOI
We Acquire Vocabulary and Spelling by Reading: Additional Evidence for the Input Hypothesis
TL;DR: The most promising hypothesis is that vocabulary and spelling are acquired in fundamentally the same way the rest of language is acquired as discussed by the authors, and these areas can be useful laboratories for the study of language acquisition in general.

General Mental Ability in the World of Work: Occupational Attainment and Job Performance.
Frank L. Schmidt,John M. Hunter +1 more
TL;DR: The research evidence is presented that GMA predicts both occupational level attained and performance within one's chosen occupation and does so better than any other ability, trait, or disposition and better than job experience.
[The second demographic transition in Western countries: an interpretation]
TL;DR: This article argued that the demographic changes since the 1950s in the Western world with respect to family formation and dissolution form a sufficiently cohesive set to warrant a more holistic treatment instead of a variable by variable approach.
Journal ArticleDOI
How Much Does Schooling Influence General Intelligence and Its Cognitive Components? A Reassessment of the Evidence.
TL;DR: This article found that much of the causal pathway between IQ and schooling points in the direction of the importance of the quantity of schooling one attains (highest grade successfully completed), which fosters the development of cognitive processes that underpin performance on most IQ tests.
