Voltaire — To learn who rules over you, simply find out who you are not allowed to criticize
While most of us know that the answer isn't what they think it is, the problem requires some basic number crunching. A first-year college student, or even a second-year high school student, could do this with help from Excel and the internet. Hypothesis: The decline in IQ is slightly less than that predicted by shifting demographics.Divide the population in the declining graph into black, white, hispanic, and asian. Assign them each a "static" IQ based on the accepted numbers (Blacks: 85-ish; Asian: 104-ish; White: ~100; Hispanic: ~92). From there on, it's just a weighted average, where only the weights are shifting. Look at the population by year and solve with Excel. I put in these steps in the hope that someone here gets his kid to do it, or does it himself.My hypothesis is that the Flynn effect may have some influence on this, but it still does; at the very least, there's no decline that's not attributable to the shifting demographics.
