The Grand Patchwork

Since, the quantitive section of the GRE does not test statistical knowledge that is relevant to Psychology, then why is it an admissions requirement? The test only measures how well you know how to take the test and how easily you are duped into falling for its tricks. This is therefore, not a valid measurement of statistical skills in psychology, let alone the maths that they are supposedly testing. While taking Psychology we are taught about questionnaires and are required to test and look for validity and reliability. The General GRE test may be reliable but it is not valid because it doesn't measure what it is intended to measure. How is it that we have to keep up with these fair, yet strict standards and test and retest our measurements while the GRE remains an accepted graduate admissions requirement? Does anyone else find this hypocritical?
