You can find a large benefit to applying the scientific method to your beliefs in life.
In other words, one of the best ways to grow intellectually is to take things you believe to be right, and methodically and logically try to prove them wrong.
Typically, most people do the opposite, they decide something is right, then they seek out research to validate this belief. Unfortunately, in science you can’t prove what it is, you can only prove what it isn’t.
And while that last sentence is extremely vague and almost proverb-ish, the fact remains, you will see amazing growth in your understanding and knowledge if every once in a while you systematically and logically try and disprove the things that you believe to be right, instead of always trying to reaffirm their correctness.
This works amazingly well in the realm of nutrition and fitness.

PS – it was the use of this approach (borrowed from Karl Popper’s Philosophy of Science) that changed my life and led to the writing of Eat Stop Eat.
