Reagan would be unlikely to provide support to unwed mothers, but maybe as part of a deal in which he got what he wanted, a reduction in expenditures.

When I did fieldwork in the late 1960s in backcountry Botswana I hit upon the idea of asking my sister (a dairy farmer) to send me a box of back issues of American cattle magazines. It was unbelievable: I could have made a fortune selling pictures from them, not to mention whole issues, to the local cattle people. At that time people carefully hoarded little scraps of paper to use writing messages.

In the late 1980s I brought some more such magazines with me, and no one was interested at all. The media storm had penetrated and everyone had school textbooks, magazines, radios, etc.

It is an interesting puzzle. This was a secular rise in cognitive test scores well documented in a number of countries during the 20th century. It has stopped and even reversed in the last few decades. There seem to be several pausible ideas out there

One is that social changes have had the effect of "training" people for cognitive tests: more magazines, radio, chatter everywhere, advertising, etc. Hard idea to test. I do fieldwork in Southern Africa. Forty years ago there were no radios in the backcountry, no books, no magazines. Today radio, newspapers, magazines are everywhere. I expect that this changes people a lot but I have no evidence.

Flynn himself thinks nutrition got better but the data are not clear about that. I would favor as an explanation vaccination and antibiotics. Infectious disease and the inflammation associated with it does seem to damage people (Caleb Finch, Eileen Crimmins, others). We have cut the intensity of childhood insults way down everywhere.

My two cents........
