My understanding of IQ is that its not fully heritable... an individual's potential is maximized by their environment, up to some limit. This alone gives a strong argument for improving public schools especially where students may be falling behind. So I am still not understanding the complacency aspect fully. I suppose a bigoted person could say "well those kids are dumb, they're expected to do bad." But the counter to that is, "they can do much better than they're doing," and the science would support it.
