It is said that, "variety is the spice of life." 

The fact that people like variety in what they read and assimilate is no secret either.

According to Dr. Michael Shermer there is a reason for this called patternicity. This is the tendency to find meaningful patterns in both meaningful and meaningless data. The second process he calls agenticity: the tendency to infuse patterns with meaning, intention, and agency.

Is seeing and reading tantamount to believing? Shermer says: "We can’t help believing. Our brains evolved to connect the dots of our world into meaningful patterns that explain why things happen. These meaningful patterns become beliefs. Once beliefs are formed the brain begins to look for and find confirmatory evidence in support of those beliefs, which adds an emotional boost of further confidence in the beliefs and thereby accelerates the process of reinforcing them, and round and round the process goes in a positive feedback loop of belief confirmation. Dr. Shermer outlines the numerous cognitive tools our brains engage to reinforce our beliefs as truths and to insure that we are always right."

Did you ever pay attention to the types of things you like to read and how they affect you or shape you? Does it really matter - what we read and whether we believe it or not? Whether believers or nonbelievers, we are all driven by the need to understand the universe and our place in it. And that, about sums it up.
