A lot of changes are due to the chemicals in the food and lack of nutrients ,eg magnesium, in much of the food supply. Also an overabundance of if linoleic acid in diet with lack of dha( from natural sources). Most of the brain is made of dha, which we do not make well, we must ingest. The researcher MIchael Crawford PhD compares Dha in the brain to quantum switches if you want to do search on his writings

Just saw my dentist this morning and we talked about this. He didn't get the jab, either. He's doing the cleanings now because he can't find any decent hygienists. Decent means...drama free, able to follow direction.

George Carlin said it long ago:
"Think of how stupid the average person is, and realize half of them are stupider than that."
Society has for, thousands of years, been filtering out the less intelligent ones through natural selection, but in the last century, technology and government have contrived to make the world safe for, and promote the survival of, morons.
They are now treated as an endangered species, and woe to your bank account if something happens to one and their lawyers can blame it on you.
Modern society protects the ones it wants, not intelligent people, males, White people, Christians, heterosexuals or conservatives.

I am amazed you can get them to even read your emails, much less understand them. I've noticed an uptick in usage of the "TLDR" concept (too long; didn't read). People seem to be annoyed if one wants to convey to them anything more than the smallest byte of information at a time.

I do contract work in a reviewer capacity for some consumer products. Other reviewers get practically hostile when they see a long, comprehensive review, because they think it makes them look bad in comparison. And frankly, I think it does! Their main criticism is "no one wants to read a dissertation!" But if I am thinking about purchasing an expensive product, I appreciate seeing a comprehensive discussion of its merits.

And at the same time, these people complain that their reviews are often rejected, and can't imagine why.

I don't know what the answer is, but yes, I see a similar lack of intellectual capacity, and also, a lack of intellectual curiosity. I am not sure which is more frightening.

I think the purveyors of the jab are getting exactly what they set out to get: a dumbed-down populace.

I teach English at a local college. Students are to put the full heading on the upper left, and their last name and page number in the upper right. This week, several weeks into the semester, I am still getting papers with Last Name instead of their last name.

Abaco, is there supposed to be a link when ya click on "I'm scared about the brains..." ?

I can't grasp what you are talking about, either, as I don't know what area of tech you are talking about.

Look at Washington and their poodle-dog media to encounter stupendous stupidity - "Let's lob long-range missiles into Russia, that will bring about peace."

One reason many people appear "stupid" is because of the growth and reliance on jargon and acronyms, as a result of the explosion of technology and its multiplying specializations.

For example, I do not know what a "shrug job" is, and even the dictionary is no help in understanding what you mean by a "somewhat complex design problem" so I am stupid? LOL! Look at Reddit to see acronyms galore. The deeper the discussion the worse it gets.

How are you "explaining" it? If there's misunderstanding it's not going to be resolved by changing the format of the explanation. You need some sort of feedback mechanism to figure out why they don't get it.

Start with the basics. Start with one sentence. Does the person understand that one sentence? Do they understand every word in that sentence?

Another reason for "stupidty" is the disintegration of the public education system. It was reported not a single person "graduated" from Baltimore public schools able to read at "grade level" or do simple math.

Do you have a glossary of the terms you are using in your "design process"? Terms with different meanings than those offered in a dictionary or compounds that are not found outside your tech area? Don't assume your team knows the vocabulary of your specialization.

That's how I clear misunderstood words and resolve acronyms and creative compounds. If there's no look-up to explain each and every word, compound and phrase, then that "system" is not easily operated.

There's nothing organically different about people's brains, unless one is being prescribed psychotropic ("reality-altering") medications. That is a huge and growing problem in America and leads to diminished understanding. Persdonally, I thin it has lowered the societal sanity level. But that is each person's private medical information, we certainly don't want to prevent Big Pharma from becoming $trillion dollar corporations by exposing the harm they do to the country by creating a dysfunctional society, do we?

After reading a few of the comments here, it makes me glad I retired when I did. A comedian named Greg Travis summed it up better than I ever could. He said "This is for the stupid people; you know who you are. Maybe you DON'T know who you are."

I've been calling it out as:
"Everyone is surfing on the edge of their incompetence..."

We keep seeing it in various companies. People who are managers that need to go through things in the order they have them written down AFTER we went through 80% of them in a different order in THIS SAME meeting.

People who listen for 10 minutes to an update, and say "I'm sorry, I couldn't follow you. Could you say it again?"

As I get older, I am "word hunting" a lot more. But this is SO FAR beyond that, I am concerned for our countries future.

The current leaders are failing "standing up". And their replacements are best described as "The Cream of the Crap!" (not CROP).

It's not 100%, obviously. But it's like the smart people in the long established companies are fleeing and signing up with consulting firms.

And this H1B Visa Tax (a WONDERFUL IDEA) is going to crush a BUNCH of companies as they are going to be forced to hire locally, or do more offshoring. Into a world of "Brain Fogged" people.

And I am an OPTIMIST, FTR (for the record).

Out of curiosity, and if you don't mind explaining, what is the design problem that you were trying to explain.?
