My favorite cognitive bias is the “attentional bias.” It’s scientific evidence for the idea that your life is a result of your thoughts. The attentional bias states that our perceptions are affected by our thoughts. And naturally, our perceptions determine our actions and decisions, which make up our lives. If you have negative thoughts, you also have a negative perception of life. That’s what it says. Our mind might be illogical, but it’s also simple at the same time.
