Thank you for clarifying. But one question still remains unanswered to me: do you think there are a certain number of people in society who do not have enough intelligence to go into certain fields?
Absolutely. I believe that for certain endeavors there are requirements, physical, mental, social, etc.
Let's talk about physical intelligence/kinesthetics: I'm a pretty good swimmer. Spent my HS and college days teaching swimming. Could I have become world class even with a lot of practice? Probably not. There is something Michael Phelps has that no one else has; he has whatever magical combination of body type, work ethic (although that has been debated), etc. that no one else has.
My mother was a model. She was/is beautiful but she didn't have what it took to become a "supermodel" (not that that even existed in her day); she wasn't tall enough, couldn't work the camera to her best angle and has little sense of where her body was in space (I woefully inherited that from her and it terribly damaged my tennis serve. LOL).
Intelligence as measured by standard metrics is also required for certain endeavors. Ryan Lochte - to use another sports analogy. Great swimmer, questionable fashion designer. Do I think he's intelligent? No, at least he wouldn't score above average on the WAIS.. Do I think he's below average? No, but I also don't think he is bright enough to be a physician, or engineer, or chemist.
Do you think it would be possible for a person with an IQ of 85 to become an emergency physician?
There's a loaded question...
Possible? Perhaps. Likely? No. I would venture that an average level of intelligence is necessary for most white collar professions.
As to what I was saying earlier, I agree that it is possible for someone with a 110 IQ to become a physician, but it will be relatively few and it would be an uphill battle the whole way, starting with undergraduate studies.
There is where we disagree. 110 is a reasonably normal IQ score. Since an IQ above 130 represents less than 2% of the population, are you saying that physicians belong to the rarified air as a rule? I'd agree with you - physicians ARE smarter than average. Most probably do have an IQ above 120 or even 130; however, there is no accounting for work ethic or laziness. One of the brightest guys I know is the son of a surgeon and an RN. Bright guy, bright family, lots of resources, a "would you like fries with that" degree from Cal. Doesn't matter - the guy isn't interested in working. He could absolutely be a physician; he understands the material when we talk about it. But he could never complete the coursework, he just wouldn't work that hard, even if it was what he wanted to do. Why should it be any different for someone who is of average intelligence who *would* put the time and work in? Did you really think undergrad and the MCAT were that hard?
