Data: A big drop in IQs for East Asians in the US

As I sit in this McDonald's being served coffee by a middle-aged Filipino man, I'm wondering how East Asian IQ is doing in the US.  Here is a graph showing trends since the 1970s (GSS data, US born, N = 107):

Wow, that's a significant drop. In the 1970s, the mean was 108.6.  By the 1990s, it fell to 99.3.  After an increase to 101.7 in the 2000s, it fell again to a low of 99.0 in this decade. 

I assume this drop is due to the increase of southeast Asians (e.g., Filipinos, Vietnamese) -- groups that have lower average IQs than NE Asians (i.e., Japanese, Chinese, Koreans).

    There's no narrowing. It's an artifact of confusing age effects with cohort effects: https://www.dropbox.com/s/thjfqpm2x2nfj3o/wordsum%20b-w%20gap.pdf?dl=0
