The importance of a given set of facts is tied to your values.

If you and someone else see the same set of facts, you could still disagree on their importance if you have a different set of values.

Values are literally what kinds of things you value.

There's no objective weighting of the importance of a given set of facts, because you need to bring your subjective values, which might differ.

Your values are tied to your beliefs, your goals, your principles.
