the possible threads that connect these three observations

what are the threads that connect the following four statements?

1. most people can't distinguish fast food from gourmet if you change how it is presented ("plated").

2. people think a Picasso painting called Guernica that looks like done by 3 year old on a bad acid trip is worth upwards of 100 million dollars.

3. we raise money for "Science research" for conditions like "Alzheimer's" and an economic analysis shows over 99% (virtually all) money wasted is wasted due to pseudoscience, duplicate research, misleading research, and the fact that we simply cannot treat the disease until it is too late, and it being an unsolvable problem.

4. Wall Street and hedge funds exist using unbelievably complicated algorithms and day trading, yet their strategies can be simply crushed by the "buy hold" strategy of buying stocks and doing nothing until they have matured to reach an accurate reflection of their value. Good example: buying Apple, Microsoft, Google, Amazon, or Netflix in 2003. If you held them until say, 2020, you would get around 1200-1600x your return. You do have to sell too early (because they are growing exponentially) but this problem is easily solvable using basic statistics and correlative data. Admittedy most people have to sell too early because they need the money, but doing so to ensure a profit is usually a huge mistake (over 99% sell these classes of stocks too early). I'm guessing there are over 200 stocks like these aforementioned few. Therefore, the stock market is both breathtakingly complicated and embarrassingly simple.

the possible answers? couple of things:
1. it's largely a brainwashed world for those people with access to information, and often among the wealthy ( maybe1/200 wealthy people act as if they aren't brainwashed), and many people choose products often at least partially based on how they are marketed and packaged.
2. people simply don't care about getting things right
3. wealthy people are largely morally meek, and prefer physical objects with no inherent value, to life itself
4. people with more than enough information don't apply critical reasoning skills to solve simple or complex problems
5. if you gain more information about anything, it doesn't mean you're getting closer to the right answer if you don't have ways of organizing the information, filtering it, and deciding what is most, least, and not relevant, and what "information" may be of questionable validity. 6. we get the complicated things wrong because we almost always get the simple things wrong at the most rudimentary levels. It's like trying to build a house with no foundation. 7. pathetic species (((

My final note on these observations is that, whatever you want to call it, people act in squarish ways. People do what powerful people tell them to do, and simply fail to think of the value of logical and illogical ways of solving problems, even from a basic strategic standpoint.
