Can you CHOOSE to believe something different?If you believe something, can you consciously decide to fundamentally change that belief simply through force of will and without additional information?For example (and this is literally just something random), if someone believes (as in considers it to be truth) that ice cream is unhealthy, without obtaining any new info about its dietary aspects or whatever, could that person flip that belief and start believing that ice cream is, in fact, healthy?
Please don't fixate on ice cream or diet in your response. This question is general and applies to any belief one might hold, be it about diet or politics or religion or art or humanity in general.
