Not "instead". Stanovich is pretty clear that IQ tests measure something real and useful - no debate about that. The trap he's talking about is that in most occasions people live on auto-pilot, and fail to engage their higher cognitive skills. The frequency with which they do this is largely independent of the IQ.

Unfortunately I don't think there is much study into teaching rationality skills systematically. Scientists tend to be rather methodical about such things, and they'll probably want a working RQ test before attempting to do serious teaching. And as Stanovich says, a good RQ test is doable right now - given enough time and money.
