The one area of life where Selective Exposure may be most observable is the way we choose to expose ourselves or protect ourselves from RELIGION.
And the decision that happens is whether you choose to embrace a "community of religion" that tells you what you want to hear, that reinforces what you already want to think.... or whether you embrace a "system of faith" that says: "Here is a better way for you to think... try life our way, you'll like it!"
Can I suggest something radical: While some people turn on their radio wanting to be pampered, wanting a "spa massage" experience for their ego and psyche, there are other people who turn on their radio saying: "I want to go to bed every night knowing I learned something new and useful and important today and tonight I understand my world just a little bit better than when I woke up this morning."
This conversation seems to assume everybody lives in that first category.
The "lowest common denominator" is the "greatest unwashed masses." Advertising-providers in mass media shoot for the bigger numbers.
Most people who aspire to greater things, well, mass media is probably not going to help them do that. It's too "mass." The ways people would want to improve themselves are more varied than the individuals who want to improve themselves. That niche would be impossible to serve, without cheesing off and boring almost all the other listeners.
If people are interested in personal wholesale change, they will go to a bookstore, a church, join a support group, do something active rather than just turning on a radio station.
Besides, you can't shove "improvement" down people's throats, they will be repulsed, so broadcasters are waiting on demand to provide the supply.
What does radio offer to the people in the second category? If radio is going to take a commercial message (that is the way most radio survives) and deliver it to a listener who might act upon the message and walk into the door of the advertiser for the first time.... wouldn't it be logical I would want my station to have some listeners in that second category.... people who are ready to embrace a new way of thinking, a new product, a new lifestyle.
Way of thinking, product, and lifestyle would all be marketed differently.
Hasn't politics and the way it's marketed taught us that?
The lifestyle/need for change is promoted (a slogan, say "A chicken in every pot" or "Change to make it easy"), then a product (candidate) is promoted to meet that need, and over time, that marketing might change a way of thinking (more or less reliance on government, say). None of those are things you can promote and make change happen in one fell swoop (fell enough for mass media broadcasters to be interested in), except maybe for the product/candidate and all those ads during campaigns.
If ALL my listeners already know what they think and what they want, and expect the station to spoil and pamper them, how do you effectively deliver a commercial announcement that says: "Get off your butt and do something new and different and buy my product."
Sure, people want "change," but they want it in increments, and they want it to be palatable [except in the occasional and rare "Damascus Road experience" kind of instance]. That's why they are shocked when a light AC station changes format to rock, and email the pd, as compared to being just being a little peeved and getting over it faster when they let the evening dj go and start running Delilah.
