This sort of "freedom" has more to do with upbringing than IQ. A 115 IQ is more than enough brainpower to become a doctor or attorney and a person born in that range in a family with high expectations will be expected to perform at that level. Conversely, there are people with 140+ IQs whose families expect little or nothing of them, although that sort of "freedom" isn't desirable either.

For maximizing life success, I'd say that an IQ in the low 130s is optimal, but anything above 140 is dangerous and rather useless unless you want to "swing for the fences" and achieve something that will be remembered after you die (something that, in my mind, is overrated). People selected as leaders are usually 75-90th percentile (intellectually) within their reference frame, and almost never 95+. The upshot is that the frame of reference gets smarter as one gets older; people with 130 IQs are virtually never popular in high school, but can do well in adulthood. In general, the smarter you are, the later in life you hit your stride, socially speaking.

The risk is that not everyone recovers, although most do, from the negative experiences earlier on. A 30-year-old with a 145 IQ has probably recovered from any innate social problems and become socially normal, neurologically speaking, but in the corporate world he's going to be competing against people in the 120-130 range who have the advantage of positive past experiences.
