I remember a twilight zone episode from about 15 years ago, set in a future with flying cars and fancy uniforms, the impression given is of a totally controlled society made possible by technology that is integrated into everyones lives. The story follows a kid that is a genius and for his 16th birthday, as every other kid is required, he needs to write a knowledge test, the problem is that the society has allowances on intelligence, only a certain amount of variation from the standard is acceptable, the kid is drugged with a truth potion and examined. He passes so well and is so smart that he has to be eliminated to preserve social coherence.
