Why are intelligence and research so controversial?

A question that is posted uncorrected by Quora question translator also deserves an uncorrected, by Google Translate, translated reply:

It is because the majority of the world’s population has very strong views, and most of us have a different view on intelligence.

When our strongly defended views are challenged, it can cause very intense feelings.Unless it is more of a rational opinion such as 20 ^ 2 + B ^ 2 = 25 ^ 2 400 + B ^ 2 = 625 B ^ 2 = 225 B = 15. That is rather difficult to be emotional about. But opinions like “I like it (add the name of the footballer) because he is the best” is more of an emotional opinion. Well, we have no clear understanding of intelligence, so we use our intuition to describe it and make assumptions. Make research around them very controversial.

Look at this brain scan of Jim and control (red is high activity, blue is little activity)

What do you think of the two brain scans?Well, if you don’t know what Jim has, you’d probably have assumed that the control is average in terms of intelligence (possibly clever) and Jim is stupid and slow. Well, Jim is actually an American neuroscientist. He is professor of psychiatry and human Behavior and emeritus professor of anatomy and neurobiology at the University of California, Irvine School of Medicine. He simply has a neurological condition called ‘ psychopathy ‘. In interviews He is a clever guy.

The reason why he got his brains scanned is because he needed a brain scan of someone who was normal to compare it with others he was studying.Well, assuming he was a normal person, he let his own brains scan along with his family. Well, when the brain scans came back, he thought, “This is the worst case of psychopathy I have ever seen”, not knowing it was his. Then he looked at the name and he was it.

He had absolutely no idea that he was a fully inflated psychopath.There were no changes in intelligence and no noticeable psychopathic traits on the surface, along with a seemingly stable relationship with his wife. For him, the idea was that he was a psychopath, an irrational idea, until he had his brain scan checked.

Funny/Cool right?

The case with bipolar disorder.

In bipolar disorder, IQ is super unpredictable.

Let’s say there is a girl named Carly, she is a normal acting person with an IQ of 130 (on the boundary of genius).Goes to collage for a PhD and has a stable social life. Well, one day the gene that causes bipolar disorder comes into action.

During her manic states, she can simply be excellent with special skills and language and processing speed.They can even have an increase in eyesight and general sensory input. She can obtain the highest grades in the college she attends to all others and her Copenhagen papers may be written in extraordinary detail.

She can also make silly choices during her manic state (such as impulsive spending or random road racing, or even extremely hassle-prone behavior) that may completely contradict her elevated IQ.Usually when mania goes too far, it becomes a force of evil in someone’s life. Here is a brain scan of a bipolar manic episode compared to a normal person.

During the depressive episodes, her IQ can greatly decrease due to the slow processing speed and the low to no motivation to do things.She may also not have the motivation to remedy her logical mistakes while she is doing it or really no motivation to think about things.

Her college qualities fall low from top student with excellent resarch papers to the A-a-girl who writes just enough to survive.Here is a brain scan of a depressive episode.

Bipolar people also have a decreased executive function over time.But in bipolar disorder, intelligence is unpredictable. Bipolar disorder is the nickname of the gifted disease before.

Savant syndrome.

Anyway, other reasons why intelligence can be very unpredictable is the case of savant syndrome.What savant syndrome is is a person with an intellectual disability who has genial abilities in a specific thing. Some examples are: can not read or speak, but can perfectly sculfy, painting with stunning details but not much else can do, remember a few thousand digeten of PI and not be able to open a door because you do not know how to Must use a slot.

This is Kim Peek, a savant who has an IQ of 80 (disturbed but not retarded) and he had a great memory.In fact, most of his IQ was due to his memory. He could read 2 pages in a book, one with each eye, and save everything, and he would do it in seconds. But he couldn’t make simple small spatial puzzles, or fold his clothes straight or do basic things without anyone there to help.

Most of Mark’s ability to solve puzzles would simply be a possibility to memorize various facts that can help him to find puzzles and use them to figure out.Sorta useful.

Now let’s go to Jake.Jake spends the same amount of time remembering mathematical equations and how they work. You know, he buys a bunch of math books and studies the comparisons a lot. Eventually you get hardcore math theories and ideas. Jake finally comes to the point of creating his own mathematical theory.

After a while, Jake could solve incredibly many puzzles.Random sequences he hasn’t seen before? Easily. Get Java for programming? Easily. It goes on. His ability to figure out puzzles comes from remembering useful things and being able to recall the right things for the right moments.

Its IQ would rise with 120, up to 132, a tremendous upswing.


It is controversial because intelligence is very unpredictable, yet we make assumptions about what intelligence actually is. Research is constantly breaking assumptions.

I hope this helps.
