Why are you all quoting 150? I said 130 to 150 not 150, first get your facts straight.To reiterate, complete horseshit. You cannot raise your IQ from 100 to 150. I would recognize someone with that level of intelligence by their sentence structure. Your IQ is largely fixed for life. That is blunt. And it is the truth. Binary logic. The only exception to this is if you suffer from a psychological condition which masks your true intelligence by diverting your attention or impairing your memory.It's not, I was truly dumber before and that was because my serotonergic system was too active while my dopaminergic system was very low. I was extremely lethargic near to CFS.I agree as some of you have stated, that hard work should be the foundation. BUT come on guys! Don't fool yourselves into believing that dedication will make you a genius. It doesn't matter how much you want something, if you don't have the optimal genetics. A person with an IQ of 100 can be the hardest working guy on the planet, but still he won't ever be able to achieve a PhD in physics. No way on earth renfr that you can "push" your IQ from 100 to 150. That's just childish...
Before when my IQ was 100 I was sometimes even giving random answers to difficult questions or answers I'm not totally sure of.
When I did one again not only I was able to decode the mechanism to solve the problem but also I was able to give a firm answer therefore I don't find it surprising if it jumped by 30 or even 50.
Saying they will never is really a blunt answer, how can you know that? I know people who were pretty dumb but managed to make something out of their lives be it become a successful entrepreneur or get his degree.
Besides gene therapy might change it all, people with organic brain syndrome or traumatic brain injury could recover their function very fastly just by changing a subset of genes.
I don't know if online IQ tests can give us an answer near to reality (I know there are some serious ones) but I remember doing them and be around 95-105, I have found a website which seems serious and has 10 IQ tests all with random questions each time so I will try it out when I got the time.
Think of the brain as a muscle. Like a muscle, training it improves it with time by the formation of more efficient synapses. But as anyone at the gym knows, some people are just naturally bigger and achieve greater gains. Others hit a limit determined by genetics. So too it is with intelligence. It's good to think of people as being born with a natural range. You need to practice to utilize the upper end of this range. But you will never surpass someone who is naturally gifted or is a genius.
I think it needs to be said that genius is a subjective term. But going by the OPs definition, the academic one currently accepted by psychometrics, I think we are talking about high IQ. With a high IQ comes an increased ability to problem solve, better acquisition of facts, and more mental stamina. This ability is largely innate and can only marginally be improved (I would guess 10 points at most) by extensive supplementation and learning. You have to accept hereditary limitations so that if you are not gifted chances are you never will be. This should not be confused with achievement. You do not need a super high IQ to make a mark on the world. Always aim to reach your potential as you never know where that is.
No, IQ is not fixed at all, this is really pure BS.
The fact that you are saying "this is the truth" shows that your reasoning is biaised, also binary logic is usually not a good thing at all...
There are many studies which studied IQs between people having no degree, having a bachelor's degree, a master's degree or a doctorate. There were significant results (and not +10 like you say), it's obvious that people who study more are likely to have an higher IQ than those who doesn't study at all or get intellectually low jobs.
Following your logics then we can all say aurevoir to neuroplasticity, epigenetics and so on, everything is fixed from the beginning so it's pointless to do anything about it, that's what a call a blunt reasoning.
Most of people do not exploit their brain to their potential so you may be right when you say there is a limit, of course there is but you're unlikely to reach it in your life.
For 90% of people with no big genetic impairment it's not a problem, of course it will be very difficult or almost impossible to raise the IQ of someone with mental retardation .
Dual n back therapy, learning hard, eventually take supplements that increase neuroplasticity will help gaining a lot of IQ points, checkout Dave Asprey, he managed to higher his IQ significantly as well, I think he has an account on Longecity. He boosted it by more than 20 points.
Also sentence structure has nothing to do with IQ, it's like saying "you don't understand fermat's theorem so you can't have an high IQ", that's bollocks if the guy in question has never studied maths thoroughsly.
You can have an high IQ and be only able to form basic sentences just because you don't read much, that's my case (for the sentence part) since I don't have much time to read books with complex grammar, so why the ad hominem attacks? Besides my past doesn't help at all, let's think about the future instead of looking backward.
Anyway my point was that you can always become better, the limit is too high to be reached for most of us, you can always reach an higher state of reasoning, it's not optimism, it's what we can see empirically.
Brain intelligence is mostly not about size, in fact its size is too huge to be truly significant, there's this story of a guy with hydrocephalus and his brain is just a thin layer among a sea of water. Yet he can function normally though his IQ was 75 but 75 is still above retardedness.But as anyone at the gym knows, some people are just naturally bigger and achieve greater gains. Others hit a limit determined by genetics.
One interesting case involving a person with past hydrocephalus was a 44-year-old French man, whose brain had been reduced to little more than a thin sheet of actual brain tissue, due to the buildup of cerebrospinal fluid in his head. The man, who had had a shunt inserted into his head to drain away fluid (which was removed when he was 14), went to a hospital after he had been experiencing mild weakness in his left leg.
In July 2007, Fox News quoted Dr. Lionel Feuillet of Hôpital de la Timone in Marseille as saying: "The images were most unusual... the brain was virtually absent."[11] When doctors learned of the man's medical history, they performed a computed tomography (CT) scan and magnetic resonance imaging (MRI) scan, and were astonished to see "massive enlargement" of the lateral ventricles in the skull. Intelligence tests showed the man had an IQ of 75, below the average score of 100. This would be considered "borderline intellectual functioning"- which is just next to the level of being officially considered mentally challenged.
Remarkably, the man was a married father of two children, and worked as a civil servant, leading an at least superficially normal life, despite having enlarged ventricles with a decreased volume of brain tissue. "What I find amazing to this day is how the brain can deal with something which you think should not be compatible with life," commented Dr. Max Muenke, a pediatric brain defect specialist at the National Human Genome Research Institute. "If something happens very slowly over quite some time, maybe over decades, the different parts of the brain take up functions that would normally be done by the part that is pushed to the side."
And that's his brain !
