If these tests 'suck' then why does every military in the world use them?
Why do all the airline sponsorships use them?
Why is it that I can show you a direct correlation between the average grades of Course A - those that have passed an airline psychometric assessment; and Course B - who have not? That correlation being that those who have passed the tests get higher grades.
Same school, same instructors, syllabus and time period.
Deal in probabalities and not absolutes and you'll discover psychometrics to be a useful tool PARTICULARLY in aviation - the sphere for which they were first invented and deployed...
