What Should We Be Worried About: Real Scenarios That Keep Scientists Up at Night (2013)John Brockman

7. Larger families are likely to be poorer, and poverty triggers earlier puberty and earlier reproduction (a good deal of recent research suggests that this phenomenon is linked to biological life-history patterns and unfolds independent of any normative inputs from religions or local culture). These factors combine to ensure that poorer, less-educated young people are more likely to stay that way and produce the next (slightly larger) generation of poor, less-educated young people.

The chapter explores the interplay between family size, poverty, education, and biological life-history patterns, arguing that larger, poorer families tend to perpetuate cycles of early reproduction and low education. It discusses the potential reversal of the Flynn Effect due to demographic shifts and the political consequences of a growing anti-intellectual population that may reduce funding for education and scientific research, thereby undermining economic growth. The chapter also includes expert perspectives on the challenges of public understanding of complex issues, the cultural foundations of human intelligence versus AI, and the socio-economic implications of automation and technological advances.
