New paper out: The personal Jensen coefficient does not predict grades beyond its association with g
Found null results for a proposed metric (actually two). In the spirit of publishing failed ideas, I wrote this up.
General intelligence (g) is known to predict grades at all educational levels. A Jensen coefficient is the correlation of subtests' g-loadings with a vector of interest. I hypothesized that the personal Jensen coefficient from the subjects' subtest scores might predict grade point average beyond g. I used an open dataset to test this. The results showed that it does not seem to have predictive power beyond g (partial correlation = -.02). I found the same result when using a similar metric suggested by Davide Piffer.
