Sigh
You keep working from (and then ignoring the results of) logical fallacies. By the time I got involved in the thread, you were using the false premise of “you need a PhD to teach university classes” which led to your faulty conclusion in deductive reasoning.
Now, you’re trying to set up a false dichotomy or a strawman where one actually doesn’t exist.
Automotive repair:
I come up with a way to increase gas mileage by making an adjustment to valve timing.
What’s going to happen from here?
I tell an auto mechanic buddy of mine what I did. He makes the same adjustment to his valve timing and gets better gas mileage. He tells a friend, who does the same, and gets the same results.
In other words, we’re essentially following the scientific method, with peer review. I performed an experiment based on a hypothesis (adjusting my valve timing in such a way will increase MPG performance) which led to a positive result. The question now is: can my experiment be replicated by someone else? If it can, then let’s publish the findings in the GM automotive tech manual for that particular car, because it works. If my experiment cannot be replicated, then either I had flawed measurements, I’m a liar, or whatever. Whichever way, my (failed) technique doesn’t make it into the GM tech manual.
That’s the scientific method/peer review in a vocational context.
In my field, let’s say I write a paper with the thesis that Shakespeare was a homosexual. I base this on my finding that “Shall I compare thee to a summer’s day” was written from a dude to a dude. I send my paper into Shakespeare Quarterly for peer review, where a panel of 5 Shakespeare experts read my paper, examine my evidence, and (of course) say “um, no. He’s writing from a male to a male, but the more likely interpretation is that it’s a letter to HIMSELF as a younger man.”
My thesis is invalid, and my paper isn’t published.
You can find a few examples of the process being fraudulent, sure. But the overwhelming majority of the time, that’s how academic study works in all fields.
What are your educational/academic credentials, if I may ask?
