1. find an issue you either really support or really can't stand.
2. google the exact opposite viewpoint.
3. think from their perspectives.
sure, there's practically infinite information out there and we don't know where to start. sure, we'd like to get to the real truth right now, but everyone has a different point of view. every week a new report comes out that asserts and debunks a well-known fact.
by and large, truth and wisdom is gained from a process, rather than something that is given to us in a nice package for our instant digestion.
