Why do we seek certainty where there is none? In some cases, artificial certainty can do us real harm, but we still desire it.
In this article, we learn that the brain actually craves certainty:
“A sense of uncertainty about the future generates a strong threat or ‘alert’ response in your limbic system. Your brain detects something is wrong, and your ability to focus on other issues diminishes. Your brain doesn’t like uncertainty – it’s like a type of pain, something to be avoided. Certainty on the other hand feels rewarding, and we tend to steer toward it, even when it might be better for us to remain uncertain.”
