I have tentatively suggested that one good way to assist worldwide development would be to promote a “Global Flynn Effect” – a rise in the general cognitive ability (GCA) of nations.
Part of this would mean measuring and tracking changes in national GCA more effectively. At present, it can be gauged using cognitive tests as well as the three existing cross-national efforts to compare educational outcomes – PISA, TIMSS, and PIRLS.
I would like to see one or more of the numerous development agencies, such as the World Bank or the UN Development Programme, coordinating this more comprehensively and more systematically.
Here is PISA coverage of nations: not bad, but much of the world is left out.
Here is TIMSS coverage:
Here is PIRLS coverage:
