This is an extremely good analogy that I must remember (if case anyone quotes this myth to me again, which hasn't happened in a couple of decades... :)

I don’t think anyone except Luc Besson still thinks this is true anymore tho..

I know that reference. When I watched that movie I was just like ugh, and then I continued watching, and it just got worse.

I intuitively understand that we're using the whole of our brains in the same way that we use the full capacity of NNs and discard the majority of results. In other words the"unused" 90% of our brain is actually importantly figuring out all the less good fits that are essential for the ultimate deductions we utilize.

Left brain vs. right brain thinking is another myth about the brain that seems to be much harder to dispel. https://en.wikipedia.org/wiki/Lateralization_of_brain_functi...

And human brain, mammal brain, lizard brain, stacked.

The triune brain model[0].

Both have the issue that the popular interpretation of them are great oversimplifications of models that themselves do seem to have some limited use in neuroscience, but only if you add enough caveats.

So unlike the situation with, say, flat earthers, there's some kernel of truth to it that can be misinterpreted or willfully presented in a misleading way.

Absolutely true, but there somehow seems different quality to them. The myths of old seemed to be little factoids that were not easy to verify and were taken at face value, then just spread until they became "common knowledge". The new ones seem to have an almost religious quality to them. Flat-earthers for example, if someone told me 25 years ago that this would be a thing I would have just laughed.

> if someone told me 25 years ago that this would be a thing I would have just laughed. Wikipedia says In the modern era, the pseudoscientific belief in a flat Earth originated with the English writer Samuel Rowbotham with the 1849 pamphlet Zetetic Astronomy. In 1956, Samuel Shenton set up the International Flat Earth Research Society (IFERS), better known as the "Flat Earth Society" from Dover, England, as a direct…

I don't doubt that the belief has always existed somewhere; tribes with barely any outside contact, for example. I suspected that the belief was once reserved for a few eccentric crackpots and didn't have the momentum to be a movement until the last decade or so, but maybe I'm wrong. Flat-earth theory probably wasn't the greatest example. I think a "myth" connotes something a bit more innocent than a delusional belief or conspiratorial thinking (I'd call the Loch Ness Monster an myth, but I'd call the "moon-landing was faked" a conspiracy).

It's amazing to think how common these sorts of myths used to be before the internet. If you heard something like this and wanted to challenge it, you would have to get on the bus and spend a couple of hours at the library and return with some photocopies. Now you can pull up Wikipedia on your phone.

There are plenty of post-internet myths that are humming along just fine. :D It's a crazy phenomenon to watch play out.

Pre-internet, it was harder to debunk myths but also harder to spread them. Nowadays, it’s easier to debunk myths but also much easier to spread them. These do not necessarily cancel out; as they say, “the amount of energy needed to refute bullshit is an order of magnitude larger than to produce it.”

As an extreme example, pre-internet, a conspiracy theory-inclined person might randomly run across a handful of full-blown conspiracy theorists in his day-to-day life. This makes it easier for him to question his leanings, since he only observes a small minority of people going all-in on the conspiracy theory. Nowadays, a conspiracy-inclined person can easily find online communities comprising all other full-blown conspiracy theorists everywhere the world. This quickly reinforces his belief in the conspiracy, since he sees an apparent majority of people in this online community believing the myth.

Another similar myth is the one Malcom Gladwell made up about how it takes 10 000 hours of doing something to become an expert at that thing. It was based on research that used 10 000 as an average for 20 year old violinists. The original researcher, Anders Ericsson, focuses much more on deliberate practice than sheer quantity.

10,000 is a round number representing a large fraction of a young person’s life, ~20 hours a week for 10 years. It seems significant because we assume talented young people can be experts if they spend a lot of time on something, but it really just reflects the criteria chosen for defining experts and time on a subject.

A prerequisite of becoming a Doctor for example is learning how to read, but that’s not considered part of the time commitment. Recursively when considering how long it takes to be an expert Heart Surgeon there is a tendency to ignore how long it takes to become a Doctor.

This reminds me of the first "scientific myth" I witnessed.

It was in the 80's in France where we had a photocopied page with "the most dangerous additives". The worst was E330. 40 years later, I still remember it.

My parents had a copy from sime friends and these well educated people (dad is an engineer and mom a lawyer) checked everything against the list. Just because it was "from the Villejuif hospital".

It was a fake and E330 is citric acid, a benin product. https://en.m.wikipedia.org/wiki/Citric_acid

The famous list: https://en.m.wikipedia.org/wiki/Villejuif_leaflet

Ericsson's main point is that talent isn't as important as a lot of people, including other experts in the field, think. What matters is identifying your weaknesses and training specifically to improve those, often with the help of a coach. Just doing something for a long time doesn't necessarily make you great at it.
