Hear, hear!

Yes. My high-school (and maybe junior high, IIRC) science classes 
covered the scientific method at least. So that much is good (at least, 
where I was anyway).

Yes, people use entirely different mindsets for different topics. Seems 
to be an inherent part of the mind, and I can certainly see some benefit 
to that. Unfortunately it can occasionally go wrong, like you describe.

Definitely. I can always spot a commissioned (or "bonus"-based) salesman 
a mile away. A lot of their tactics are incredibly irritating, 
patronizing, and frankly very transparent. (But my dad's a salesman so 
maybe that's how I managed to develop a finely-tuned "sales-bullshit 
detector") It's interesting (read: disturbing) how convinced they are 
that you're just being rude and difficult when you don't fall hook, line 
and sinker for their obvious bullshit and their obvious lack of knowledge.

Here's another interesting tactic you may not be aware of: I'm not sure 
how wide-spread this is, but I have direct inside information that it 
*is* common in car dealerships around my general area. Among themselves, 
the salesmen have a common saying: "Buyers are liars".

It's an interesting (and disturbing) method of ensuring salesmen police 
themselves and continue to be 100% read-and-willing to abandon ethics 
and bullshit the crap out of customers.

Obviously customers *do* lie of course (and that helps the tactic 
perpetuate itself), but when a *salesman* says it, it really is an 
almost hilarious case of "The pot calling the grey paint 'black'." It's 
a salesman's whole freaking *job* is be a professional liar! (And 
there's all sorts of tricks to self-rationalizing it and staying on the 
good side of the law. But their whole professional JOB is to *bullshit*! 
And they themselves are dumb enough to buy into their *own* "It's the 
*buyers* who are disonest!" nonsence.)

Casinos are similar. Back in college, when my friends and I were all 19 
and attending a school only about 2 hours from Canada...well, whaddya 
expect?...We took a roadtrip up to Casino Windsor! Within minutes of 
walking through the place I couldn't even *help* myself from counting 
the seemingly-neverending stream of blatantly-obvious psychological 
gimmicks. It was just one after another, everywhere you'd look, and they 
were so SO OBVIOUS it was like walking inside a salesman's brain. The 
physical manifestation of a direct insult to people's intelligence. It's 
really unbelievable how stupid a person has to be to fall for those 
blatant tricks.

But then again, slots and video poker aren't exactly my thing anyway. 
I'm from the 80's: If I plunk coins into a machine I expect to get food, 
beverage, clean laundry, or *actual gameplay*. Repeatedly purchasing the 
message "You loose" while the entire building itself is treating me like 
a complete brain-dead idiot isn't exactly my idea of "addictive". If I 
want to spend money to watch non-interactive animations and occasionally 
push a button or two to keep it all going, I'll just buy "The Last of Us".
