What 40 years of research has shown on beliefs?

You have probably tried to reason with someone who is invested in something they believe but unfortunately whatever it is  - it is not based on facts.So, over 40 years of research has shown that once someone is invested in a belief the probability to change their mind is extremely low. This tells us that we are wasting our time in trying to reason with these folks. Do you agree?
