In short it's about people wanting to belong to a group so they adopt an opinion or ideology simply because it makes them part of the group more so than because the opinion is valid scientifically / empirically.
To stay a part of the group they accept the groups views regardless of what the evidence suggests. Then it becomes a case of defending the groups views from outsiders.
Economics, politics, science, religion... practically anything we care to name usually has a group think component to it. Sometimes it's a dominant ideology at others it's a new dichotomy from the main group looking to break away.
People that are free thinkers tend not to become part of the dominant ideology.
I would class very few, if any people with University Degrees as free thinkers - in fact the first thing they do at University is disable the part of your brain that allows you to think for yourself. You either follow the ruling ideologies prescription or you fail - simple as that.
