I've hit on what it is: my logic is more nonverbal. On a test like this - https://www.123test.com/logical-reas...test/index.php - I don't make one mistake... The test in this thread uses a lot of terminology, etc. and so your score is highly dependent upon your verbal abilities... (And, yes, I realize that the test in the link I showed is easy, but I still screw up 'easy' questions for verbal logic tests like this one: http://www.think-logically.co.uk/lt.htm)
