Yes, I do think advertisers are naive. I've dealt with enough of them and they, as a group, seem to believe "It's important to me, so it has to be important - period." They want "yes." They can handle no. What they can't accept is "I don't care."
So, what you are saying is a "huge percentage" of ad money is inherently being flushed down the john.
And an inherently large percentage of the rest is likewise wasted because people don't trust advertising. For decades, advertisers equated sales effectiveness with day after recall. That shows they are in denial about advertising's ability to sell.
Now advertisers are trying to use technology to force people to not skip or fast forward through advertising. They still don't get it. Attention and persuasion can not be forced, at least not without the kind of control of all means of communication enjoyed by Joseph Goebbels.
