My experience with so called intelligent people is that they lack common sense.
a lot of times I see people that think that they are super intelligent. the reality is that they have above average IQ and very little wisdom. they get educated in a one of the soft science fields like sociology or in one of the non scientifically rigorous field. because they have above average iQ they do a descent job in there narrow area of education but then they think that they can comment as if they know what they are talking about in areas they have not studied....I REFER TO THEASE PEAPLE AS EDUCATED IDIOTS.
