Snake oil came first. By a likely ~ +50k years

As a freshman I had a very important Econ prof and his 101 class came
right after my Logic 101 class .After about a month I was in total confusion as everything I learned in Logic class was the opposite of what we were getting in Econ .I went to Econ Prof's office hour and told him exactly that .He looked at me and a sly smile spread over his face as he said:
"Yes it is a bunch of lies BUT they are agreed upon lies"  .

"Gosh, people sure have a lot of pent up psychotic energy."

Remember my "professional help advised"?

It took you a while to figure it out.

First, obviously, hearing is a form of perception but all perception is not hearing.

Duh?

But, generally speaking ’hearing’ is simply the ability to detect vibration while perception is considered the processing and interpretation of those vibrations in the central nervous system.

>>>>You will forgive me for saying this but that is actually incorrect. Hearing cannot occur until the brain gets involved. Therefore, it’s probably best to use my interpretation - hearing is the same thing as perception of sound. A deaf man would not hear even though acoustic vibrations impinged on his ears.

I should add that hearing/perception of sound is influenced by other factors than acoustic waves impinging in the ears. Including psychological factors, but other factors as well. I’m surprised you left psychological factors out. 😬

Guys, try to use "interpretation" instead of "perception" and it may get less tricky. Not ideal, but simpler.

Gosh, glubson, take it easy. You’re going to burn that thang out if you’re not careful.
