belief

A belief is a mental acceptance or conviction that something is true, real, or valid, even in the absence of absolute proof or evidence.

Beliefs can encompass ideas, propositions, or claims about the world, oneself, or others, and they significantly influence attitudes, behaviors, and perceptions.

They can be based on personal experiences, cultural norms, education, or faith, and can range from empirical beliefs grounded in observable realities to faith-based beliefs that transcend empirical evidence.
