[1] New facts do not always permit a change of mind because they they may support. indisputable but incompatible explanations/opinions/points of view.More facts are needed to reconcile things.
For this reason a person should strive to cultivate the skill of believing positions at the some time opinions, wholly incompatible. This is difficult. It takes effort and practice to partition your mind in a way that separates belief in one viewpoint from the belief in the other.
It is often uncomfortable [3], and for me I can only truly achieve it for brief moments. Nonetheless it's an extremely useful skill to navigate encountering new information & consider another person's viewpoint when it contradicts my own.
Ideally new information eventually comes along that explains how both can be true at the time.

[3] To reveal some very personal details, I was helped in honing this skill by having to deal with mental health issues that force completely irrational thoughts on me at the same time that I attempt, with varying degrees of success, to bring down a hammer of rational reasoning and logic against those thoughts. The former makes for a tortuous experience in itself, while the later imposes an very strange but helpful contradictory belief with both held in my head simultaneously.
