6. Surround the Topic
I often think of the quote by Thomas Aquinas, “Beware the man of a single book.”
If you only read one book on a topic and use that as the basis for your beliefs for an entire category of life, well, how sound are those beliefs? How accurate and complete is your knowledge?
Reading a book takes effort, but too often, people use one book or one article as the basis for an entire belief system. This is even more true (and more difficult to overcome) when it comes to using our one, individual experience as the basis for our beliefs. As Morgan Housel noted, “Your personal experiences make up maybe 0.00000001% of what’s happened in the world but maybe 80% of how you think the world works. We’re all biased to our own personal history.”
One way to attack this problem is to read a variety of books on the same topic. Dig in from different angles, look at the same problem through the eyes of various authors, and try to transcend the boundary of your own experience.
