I don't know if I would agree that I desire to be wrong but I certainly agree on the sentiment that I love to seek out people who disagree with me. Sure it is always nice to be reaffirmed in your believes and to a degree that is desirable as well, however the real pleasure starts when I see a strong argument that totally contradicts my world view.
To sometimes have a knee jerk reaction when the core of your believes is challenged is also only human as well. But sometimes people treat their ideas like spoiled children, in that they can never be wrong and everything they demand shall be granted.
I would say most of my life experience is anecdotal, after all I will most likely just be an afterthought of human history. But still it is my life, my real world experience, it is one of the sources I trust the most! Sure you could lay out your world view, so you are covered by some big names of the scientific, philosophical or economic community and hide behind those ideas but that's not us ;)
I went and wrote a post along these lines.
