Your post reminds of a Singapore story I was told in the late 80s - the national IQ was lowering and they analyzed it and attributed it to the highest IQ females were not marrying and not having children. Their solution was to send young men on a course to teach them "how to date smart women". The IQ curve got back on track. It would be funny to learn if in the same timeframe they removed lead pipes ALSO.
