Rsbeck,
Just talk to any engineer out there. They will tell you that they have a superior product. But for them to sell it, they need to tell you about it and convince you to purchase it instead of someone else's product.
Well, my answer to that would be -- an engineer is not the arbiter of which is the better mousetrap.
The public will tell you that.
When I was building my house, I went to a butt-load of open house audio/video demos where the latest/greatest control solutions could be experienced.
I can only imagine how many thousands of hours of engineering must have gone into these products and how many people must have been convinced that this was a better mouse-trap.
If they didn't, it stands to reason they never would have brought it to market.
It usually took me about twenty seconds to figure out that it was too complicated for my wife and family to use.
Why? Because just like your hypothetical example, it took too much explanation.
Each item would produce the "glaze over" effect.
I'll give you another example;
Years ago, there was a belief that advertising could create a need and then tell you how to fill it.
The example was under arm deodorant. It was a relatively new product, new market, humans hadn't really seen the need for it.
Advertising must have created this market, right?
Then, one of the big firms started advertising ear deodorant. They showed people in conversation, one would smell a foul odor coming from the other's ear, this would cause shame and embarrassment and then the ad told you how to deodorize your ears. The ad campaign was so unsuccessful, most people do not even remember the ads or the product.
People don't carry with them the fear that their ears might emit an odor and cause embarrassment.
Here's another some might or might not remember.
In the politically correct 70's and 80's, we were told there were no actual differences between men and women -- it was all due to socialization.
All of those TV ads advertising guns and war toys, no wonder boys want them! So -- hey (slap forehead) why didn't we think of this before?!!!
All we have to do is advertise them to girls and -- boom -- double our freakin' sales!!!
Well, it was tried and died a spectacular failure.
Same thing was tried with video games a few years later. Why? IMO, because we never seem to learn that you can't force anything on the public, you have to touch a nerve that is already there.
When you do, you light a wildfire.
Word of mouth is always your best and most cost effective advertising.
Most huge advertising campaigns are about something else -- trying to protect or reshuffle market share in markets that have already been established and where small changes will result in the kinds of profits or lost profits that make such an outlay a cost of doing business.
