Filter Bubbles

Something to think about. When a search engine only returns the results it thinks I want to read, it's not doing me a favor. It's often advantageous to hear the other side's arguments.

I know, we all think we hold the right opinions; because we've studied the issues, and listened to both sides, and evaluated with our flawless and amazing brains.  But what if we're missing data?

One thing I'm wondering about: Are there people out there who still don't know that the earth's average temperature hasn't gone up in the last 15-17 years, because their search engines only return "green" viewpoints when they search AGW?
