This is a bunch of randomly gathered bullshit, in a pile by WaPo.

It's very important to note that the metrics we used have a lot of built-in bias. Questions have been raised about racial bias in the SAT and IQ testing. What's more, college is more accessible to people of higher economic status. (There's a slight correlation between the final scores and the percentage of the state that is white, but not a terribly strong one.) Given how hard it is to identify objective metrics of intelligence, we worked with what we had.

For the state's avg IQ they used this study. pdf

Abstract
The purpose of this study is threefold. First, an estimate of state IQ is derived and its strengths and limitations are considered. To
that end, an indicator of downward bias in estimating state IQ is provided. Two preliminary causal models are offered that predict
state IQ. These models were found to be highly predictive of state IQ, yielding multiple R's of 0.83 and 0.89. Second, the extent to which state IQ predicts state outcome variables (e.g., gross state product, health, violent crime, and government effectiveness) is estimated. State IQ shows positive correlations with gross state product, health, and government effectiveness and negative correlations with violent crime. These results are consistent with the extent to which IQ predicts outcomes at the level of the individual. Third, a research agenda is provided for improving estimates of state IQ, identifying factors that cause differences in state IQ, and delineating the role of IQ in predicting important variables.

The models were "highly predictive" of a number that nobody knows?? WTF??
Sounds to me like "how do it know?" The whole paper reads like a circle jerk.
The only thing I see that rings true, is PA is solidly in the middle, as it is in all the graph/charts we've seen on every subject.
