According to Dictionary.com, triangulation is:
The location of an unknown point, as in navigation, by the formation of a triangle having the unknown point and two known points as the vertices.
When I studied history in college I had a college professor tell me that the only way to discover the truth behind an event is to read three completely different interpretations of the same event. Somewhere in the middle of all these interpretations, you’ll find the truth.
Unfortunately, it’s all too easy to only listen to one viewpoint, one interpretation; listening to those who are like minded and speak with one voice is less disruptive than seeking the truth.
