How often do your beliefs change?

[Spongebob]

Premise 1 - I reference objective information because this is the only valid form of information you should be considering. 
Premise 2 - Subjective information is too unreliable and can lead you to make serious mistakes.

Well I would disagree with the first sentence. But you're right about the second sentence. However, people are allowed to make mistakes. In fact, people are allowed to have a completely crazy world view, if that's what they want.

How can you accept premise 1 while rejecting premise 2?  They are mutually exclusive.  You can't be tall and short at the same time.

Sure you can make as many mistakes as you like.  It doesn't invalidate premise 1.  You can accept premise 1 and still make mistakes.  The point is, the more you seek out objective information, the better decisions and options you will have. 

In some ways I am talking about one's world view and sure you are free to have a crazy one, but you're only hurting yourself and possibly people you are close to.

Here's a real world example.  Objective medical science tells us that vaccinations are absolutely safe and effective and one of the most profoundly reliable forms of medical treatment ever devised by humans.  If you (perish the thought) ever meet a woman willing to reproduce with you and you have input into whether the child gets vaccinated, the objective world is telling you without hesitation the answer is YES.  Now, you are free to reject this objective truth and believe whatever claptrap you want, but you will be putting your own child at risk and possibly others that child will comes into contact with who have legitimate reasons for not getting vaccinated.  Now I imagine that to you this sounds like fuddy duddy indoctrinated atheist dogma, but that is your emotions talking to you, trying to protect your invested feelings about your accepted worldview. It's your mind fighting the realization that it is wrong about something.  This is known as cognitive dissonance and you really should listen to it.  (In fact you have listened to it in the past because you have acknowledged making changes to your religious beliefs.)  Reality doesn't give a shit about your worldview and reality is much better represented by objective information.  In reality, vaccinations are a good thing.  Hard stop.  This is based on more data and work than you likely have the mental capacity to comprehend.
