Not at all. Here's how: a) Certain professions require a certain level of prerequisite intelligence. Thus, likely that a number of people you work with will be slightly higher than 100. b) If their kids are also higher intelligence, it shouldn't be surprising. Another way to look at at: a) People lie about their kids. b) 130+ is a safe range of "smarter than 100 but not quite Mensa". Safe. == I've had jobs as Systems analyst and systems engineering. Went through the average IQs for the professions once (don't ask which one - don't remember) and 130-135ish was right in the proper range for those professions. ==
