Bold claim. Surely weak correlation between LSAT and bar passage is suggestive.
(Pearson) Correlation is the wrong method. Outcome is binary. Use proper model and it works fine. http://taxprof.typepad.com/taxprof_blog/2013/09/law-school-gpa-.html …

Effect sizes matter; looking at the regression table (and descriptions) confirm result looks weak
-
Plot shows the predictions to be quite useful. Validity mostly obscured by the low bar for passing the test.
-
Plot shows the opposite to me! You have to jump really far across the range of LSAT scores for big changes in probability

Take the -1 z GPA (least restricted). There's 7 ticks. Compare 3rd vs. 5th, for a +85% increase in pass rate.pic.twitter.com/ch4xsXSG2E

You know that using % increase rather than % point increase is highly misleading
-
Not misleading in this case. OR only superior to RR when base rate is very high. I chose the least problematic curve for this reason.
-
The curve isn't the issue! Your misleading portrayal of the effect size is.
-
Was not misleading. Already explained this to you.
