Diagnostic test for personality test

I doubt the logic of personality tests.Can you truly measure who I am?Can you discern my truth from my deceit?

I put them to the test.

I prefer solitude, but I mark "I love large crowds."I am shy, but I mark "I make friends with ease."

Predictably, the screen replies:"Diagnostic Result: You are sociable."

Will there ever be a test that sees through my lies?One that notes:"You hesitated 0.4 seconds on that choice.""Diagnostic Result: You are introverted."

If such a test should ever exist,I would offer it my applause."Diagnostic Result:You possess a brilliant mindthat thinks for itself and finds the truth."
