While I agree with you that the LSAT may not, in all cases, be an adequate predictor of one's ability to succeed in law school, I think your overall argument operates on quite a few false premises and assumptions. There need not be ANY correlation or consistency in an individual's performance on the LSAT and his or her GPA. This is true for several reasons. First, not all GPA's are created equal. A 3.1 from an Ivy League in Engineering or Biochemistry is far more impressive than a 3.5 in Speech Communications from State U. Therefore, I would see no apparent discrepancy if the Ivy grad got a 162 on the LSAT. Further, you fail to take into account that one's undergraduate experience and his/her taking the LSAT may be separated by many years. Someone who was a screw-off in college may discover his intellectual capabilities and strengths after several years of significant and challanging work experience. His newly discovered ambition may cause him to perform quite well on the LSAT. Such a performance would simply indicate that the candidate did not reach his full potential until later in life. While you personally may be bitter about your unexpectedly low score on the LSAT (as are many others), there is no need to question others' intellectual capacity based on a set of numbers even you appear to be skeptical about.
