Our internal beliefs influence our actions. Sometimes we don't take action in spite of getting new information because it does not go with our belief.
That's why, it is very important to have a open mind. If you have an open mind, you don't put level on any new information when it comes to you. It will help you to accept new things and you can adapt to the changes faster.
yeah u got it! thats when our signal to noise is really low (i.e. we're not thinking there's enough information in our observed signal to change our internal beliefs)
the real trick is: when it comes to the mind, how open is optimal???
