Scrolling down to the graphs that have all sorts of breakdowns, it looks like in general it hasn't been converging. The third group, which breaks down by race/age, looks like a mixture of noisy sameness and diverging.
- ZeroGravitas 4y agoThey address this: > For example, Hauser (1998) and Grissmer et al (1998) documented convergence of the race difference in data from the National Assessment of Educational Progress. Until the current study, this finding could be explained by a differential Flynn Effect in which minority scores increased at a steeper rate. However, we found no interaction in our data; the three different race categories each showed substantial FE’s, but they also tracked closely to the same consistent increase. So again, they accept the gap is closing, but their result suggests this is not due to a differential Flynn effect, but to something else.

- Izkata 4y agoThe second part of what you quoted disagrees, they don't agree the gap is closing. They make it explicit near the bottom: > The effect itself is strong and consistent, but we found no differential gender or race FE, nor was there much of a differential urbanization status identified. The positive finding of a differential FE in relation to maternal education (and at a smaller level, household income) at the older ages is suggestive of some of the dynamics of the process leading to the Flynn Effect. However, we do not consider our findings to be confirmatory in any sense.
