The human mind is a remarkable thing. Sometimes people go through what are called “conversion experiences”. When that happens, the person abandons previously held beliefs and adopts the new religion to the exclusion of their old one. There are powerful examples of this throughout history. You can find numerous personal stories of conversions on the internet.
Although the word is usually used in connection with religion, the same can be true of changing other strongly held personal beliefs. We’re seeing some of that in the current political climate. Some people who were in one political party are so upset with what is happening that they shift to another.
Sometimes “conversions” happen when someone abandons a habit. Often this happens because the individual has been frightened by, say, a medical diagnosis, or enlightened by new and powerful information. It’s been said that there is no one more anti-smoking than a former smoker, for example, who has been told that their lungs were precancerous or who lost someone to lung cancer. They not only don’t smoke but they try to get everyone they know who is a smoker to join them in their new life choice.
I’m not clear if those are really examples of “conversion” so much as an expression of someone’s need to reinforce their own decision until it “sticks”. But it is an effective way to change a habit or a belief system. In that sense, it answers your question. Yes, people can change their beliefs due to logic or because they have had a powerful emotional experience that causes a fundamental change in how they see things.
I wish you well.
