Bunch of things here.
Every project is different. Even the recruit is different. I've done over 500 AMTs, caused to be done over a million phone current music interviews and many one-on-one perceptuals as well as format searches, morning show evaluations, etc., etc.
That is why I say that the questions are tailored to the specific project. No two are exactly alike.
My point here is that you're asserting a general principle. An example would do, though it would not be entirely conclusive. (Mega 98.3 isn't that, for reasons I'll get into.) I'm not asking for an inductive proof here. Knowing the process is only a partial answer. And how do you know that your own unconscious bias - or commitment to received dogma - isn't entering the picture?
What David is correctly saying is; when you run perceptual or certain types of focus groups, is many times you need to ask the same or similar question several different ways. The reason is the way some people are wired interpret a question differently, and will either give you an inaccurate, or overly complicated response that isn't honest. David can't give you an example, mainly because a lot depends on what sort of answer was being sought for a particular question.
Likewise, I'm seeing assertions of a general principle but then I'm told that "every case is different". The two concepts are contradictory.
By the way, welcome back.
I just found my personal notes for the Mega 98.3 format search and name change project in Argentina in 2000. I can scan them and attach some examples.
I saw the web page but, to be honest, it appears Mega 98.3 had more problems than just running newscasts. It's a multivariate equation and your client modified multiple variables at the same time. So it's harder, much harder, to tell which one made the difference. Singling out news as being the problem would itself be indicative of a potential bias.
I know I'm being annoying here, but I feel like I'm asking honest questions and being confronted with rhetorical tricks in response. It's frustrating. I will admit to my own opinions here, based on my own experience at a research company (small, local to Houston).
So let's jump off the alternate route and get back to the main road:
If you want to talk about the public radio mission, that's also a huge part of it. The intense breaking news and politics coverage came about in part because commercial radio left a vacuum starting around the turn of the century. But the arts and cultural coverage has been in NPR's DNA since the service began more than 50 years ago, and there's little or no substitute for that anywhere else on the dial.
The linkage here is the vacuum that commercial radio has left for news coverage. The news/public affairs/politics coverage also seems to gain more listener support than arts-intensive coverage. Some public radio outfits are able to do both (Colorado Public Radio, Iowa Public Radio, KCUR, KBIA/KMUC, etc.) Others, when faced with a choice, pick news/public affairs/politics because that's where the greater support seems to be. Or the classical/arts coverage goes on a HD-2 channel. As for the interest in arts coverage, though, the demographic is definitely aging.
At some point, someone has to decide whether a radio station offers a service because it's a public good - even if interest in it is limited - or whether considerations of listener interest trump everything else even if means that certain forms of public service go unaddressed. It's a direct consequence of being in a society that dumped most non-transactional considerations for broadcasting in stages, starting 40-ish years ago, in favor of a purer form of capitalism. That affected public radio, too. I'm just describing it here; I'm not saying one form of the system is better than any other; I don't see the clock turning back, either. But we have to learn how to live with it somehow...or just give up and tell people to open up their streaming app (where the economic model seems to be even shakier).
