"Then she used her 173 IQ to pass California's high school-equivalency exam. At 19, she graduated from California State University at Fresno and took the CPA exam (scoring second best in the country that year). "
While it would be possible to verify that someone graduated from CSU at 19 (you call them) in general I would imagine that there is no easy way to verify someone's IQ or that they were 2nd best in the country at the CPA exam. I would imagine that journalists repeat things like this blindly and they become the truth about people when stated as if fact.
Of course journalists are generally going to repeat things that they are told but certain things are much harder to verify by any third party reading (as opposed to "graduated from Harvard" which could be disproved by anyone).
