See that's the thing though, I don't think that someone who scores low on an IQ test IS incapable of anything, it may take them slightly more time than someone with a high IQ but it doesn't rule them out of a field completely. People should go into a field they love, not necessarily one that plays to their strengths. I am a very good athlete, but I don't particularly like sports.
I didn't say anyone is incapable. And while you are focusing on someone's lower IQ, all along I've been saying, we need to quit doing that. And you are indirectly assuming that just because someone has an IQ, they are capable of all things. And they aren't. From what I know, people with high IQ usually struggle in at least two or more of the other types of intelligences. So, just because someone has a high IQ doesn't mean they are capable of any and everything. Many don't even know what they are capable of.
My point has been focus on what we are capable of, not what we aren't. To me, it makes more sense to play to your strengths than to constantly keep pushing at something you want to do, but yet keep struggling in. Yes, I may love the idea of being a scientist or becoming a physicist or a chemist but I know sciences are a weak spot for me. If I keep pushing to continue in those areas, and there is no real affinity, then I'm only going to become more frustrated and disappointed, thinking I'm not good at anything just because I may not be good at that thing, when I have other talents or abilities that I may have a better chance of developing.
I personally . . . and I stress personally, don't have a problem acknowledging my own limits. I am happier accepting what I can do, and what I can't. Nothing is wrong with that. On the other hand, nothing is wrong with having a dream or striving to be the best at whatever you want to do either. But, we all have varying types of strengths or intelligences. That's just a fact, not a feeling.
For example, just because I may want to be a Olympic gymnast, doesn't mean I can. There's a ton of stuff that goes into being in the profession which I'm not prepared for. Which is fine. Same thing if this was math. I like some aspects of math but I struggle with logic. Yes, I love logic, but I'm not good at it. I like the challenge of it. But unless I know I can be good at or great at something, I don't want to attempt it. But that's just me. I'm not going go in a profession where everything is a constant struggle to get or understand it when I can be in a profession which allows me to use my strengths.
