The left right hypothesis is wrong. The brain specialization is much more fine grained and much more adaptible to circumstances than described.

Yes there are some specialized loci that happen to (most often) be in the left or right hemisphere, but the original hypothesis that logic is in the left hemisphere for example is utterly wrong.

An example would be language, researchers started finding language loci in the brain (by showing that if a specific area was damaged, language was damaged) and so on. Based on such evidence the left right hypothesis was formed. What was not taken into account (in my somewhat accurate example) was that there are several other areas one could injure to get language-affecting brain damage.

The thing is, such broad things as language, or logic, or art, are not located anywhere in particular in the brain, it is the interaction or many different areas and not necessarily the same areas in every person. There are however several areas that are specialized but on a much lower level than "language" search for Wernicke's area for example.

Also note that Wernicke's area is statistically in different hemisphere more probably depending on which is your predominant hand.

So no, just no.

Isn't the key point that brain functions can rely on specific localised areas, that when those areas connections to other areas are disrupted then behaviours can be altered.

It's wrong like Newtonian mechanics, rather than like Flat Earth Theory?

There is degree to the wrongness yes. But yes I am not saying the original hypothesis was not progress at the time (unlike Freud's non contributions) the left right hypothesis did contribute at the time as it actually looked at the brain and tried to map some things.

What I'm against is referencing this idea in a context (the article) where it makes no sense, and rather lies to the reader by telling a great story based on old facts that have since been disproven.

Left right brain is wrong, not really in the same way Newtonian physics is wrong today, at least not in the form it was cited about logic being in one hemisphere. I would compare it to say, Greek anatomy. They had the idea of that things in you could be wrong. But they didn't really know what was wrong in different diseases, they came up with lots of ideas of different bodily fluids having too much or too little of one , connected to certain organs.

Now we know most of their explanations were bullshit where we can explain things a lot better. Regarding Newtonian physics my impression is that they still explain the same phenomena they explained from the beginning, but we have refined things, and realized it can not explain all things one might have thought it could explain.
