I see you've met my wife.208 isn't just the upper echelon.
130+ is the upper echelon and it gets exponential after that. 150+ is super-high.
208 is totally off the charts. If you encountered a person with that level IQ they would not seem in anyway normal. They would blaze with intelligence. They'd be more like the interdimensional beings at the end of Indiana Jones and the Crystal Skull than like a normal human.
Siena Brooks was a very ordinary person who said nothing interesting and did nothing clever.
Hannibal Lecter is a good example of a character with very high intelligence. He was also totally normal.
