counterpoint on abc national is possibly the best radio program, it tends to look at the opposite viewpoint that the media takes and presents an alternative idea, somewhat deconstructive but at the same time visionary, it's guests range from international thinkers, ideas people and the ones that fall through the gap. 

the impact on such a show like this is incredible, as perspective is given to the subjects we are so black and white about, you actually get to hear the wider concept and it actually changes your own. that's what evolution is, the ability to process information and adapt to it where necessary, every week they delve into different areas, from arts to culture, to religion and history. i love the dry wit that the presenters have and once a month a political satirist has a guest spot and he is amazing, summing up the month in an hilarious way. 

here's the link, check it out yourself, feed your mind, stimulate both your hemispheres and get a new perspective on your fixed ideas, you know its healthy.
