I got half way through Ygolo's article and couldn't read the rest...it's premise is wrong, or it feels wrong to me.
I have to think about it.
I was thinking the other day, I feel it makes a huge difference. I was dealing with a patient, who didn't understand what her doctor had told her, so she decided to bail one of us lab techs up instead. I drew the short straw. I tried everything to explain what this particular test meant. Even had a nurse who barely speaks english try and explain....(okay me and the nurse were in tears of laughter/frustration afterwards. She thought it was really funny, her english is great, it's just so obviously not her first language, and she had explain in the end.) Finally the nurse has her understanding, amazingly, even then it took her a couple of goes. I had simplified, and simplified, but what this patient wanted was a yes or no answer that was impossible to give. The Nurse explained why we couldn't say Yes or No. Either that or she was freaking out she had bacteria on her body that wasn't bad.
My point being most people tend to associate with people that have similar IQ's. Maybe a variation of 10-15 points. Say you have an IQ of 130-125. That means on a daily basis you are still talking with people of an above average IQ. Particulary if you are educated, and birds of a feather flock together. It's easier, there maybe issues with areas of expertise, but you don't have explain fundementals and assumptions....and you get lazy admittedly.
I have one of the girls at work shaking her head, every time I explain something to maintainance, and she'll reexplain it. She told me I throw too many big words in there and she doesn't understand what I'm talking about, let alone some maintainance guy.
What cracks me up was my boss says exactly the same thing as I do...and you hear the groans. There is such a thing as a communication barrier. I experience it on a regular basis, where as if you asked me when I still lived in the city, I'd have said it was an issue some times, occasionally....where I live now, it's an issue every freakin' day (I have a good deal of respect for doctors who stay here for more than two years, for instance). 15 points IQ difference makes a little bit of a difference, 30-40 (I'm not kidding, there's lead in soil here)points is almost freakin' insurmountable.
I don't consider myself a snob or whatever either.
