Nope, not even close to the key issue, which is selection bias. In other words, how representative of top law schools’ grads is LinkedIn profiles? Statistically is is not representative of anything other than people who are members of Linkedin (and who have their profile open?). Over what grad period is this survey of LinkedIn ‘customers’ or members, (as they have a free service and a pay service)?
This is the same issue for those on cc that love to use Payscale to justify ‘college x kids earn more than college y’.
Other than Yale Law and Stanford Law, law school is 95% about two numbers, so it that sense most any college is a fine college for a student with law school ambitions. Sure, attending HY may receive a small bump to their own LS, but absolutely no Adcom is gonna look at a Midd app and say, ‘wow, Midd’, and and Emory app and think ‘ewww, put in the directional state Uni pile’.
Both Midd and Emory are high quality institutions and their grads will be well received by law schools.
