Is it not? I certainly don't know or understand even a fraction of what would be considered established science, but if a credible expert tells me that something is supported by established science I will believe it over something like religious dogma. I consider myself to be a "believer" in science.
"Believe" is an overloaded word. In one sense, it's simply the content of your mental state. In basic epistemology, Knowledge is defined as "Justified True Belief", i.e. when your mental state matches the actual state of the world for the "right" reasons (this is surprisingly tricky to make formal, see [1])If your head is a memory cell, your beliefs are the actual 0s or 1s inside it. In other senses, "beliefs" are an…
In my opinion, the only rigorous way to improve our knowledge, is to employ Bayes Theorem, and Bayesian thinking in general.
You and I may have different prior on a topic. We may see the same evidence, but end up believing different things because of the prior. As long as we state the prior, that is good and fair. If the evidence contradicts my prior, I should lower the confidence I have in my belief, even if the prior was big enough that I still believe the same thing.
Unfortunately, what often happens, is that people lock themselves into believing things absolutely. If you lock some prior probability to 1, Bayes' Theorem has n way to let you update that belief.
This is especially common when it comes to beliefs related to religion and identity. In fact, this is one way to define religious belief. Anything you believe that you will NOT stop believing regardless of evidence, could be defined as religious.
If you believe in God, and we discover that Heaven is not on the other side of the starts, the believer just modifies non-core parts, and claims that "God is everywhere and nowhere".
If belief in racist oppression is what defines you, and you find that most individuals are not individually racist anymore, you can just introduce "Structural Racism" that claims that hard work, staying married and maths are racist.
