Bad becomes Good

Let's suppose a rule for the narrative X::Y that says if one of the two is Bad and one is Good, then the whole statement is Bad. If they are both Good, or both Bad then that is Good. I am assuming '::' has an interpretation as "if...then".

Here is an example that seems correct:
"if you like noise then you will like this hotel" (Bad-to-Good, a negative about the hotel)
"if you like noise then you will not like this hotel" (Bad-to-Bad, a positive about the hotel)
"if you like quiet you will not like this hotel" (Good-to-Bad, a negative about the hotel)
"if you like quiet you will like this hotel" (Good-to-Good, a positive about the hotel).

If this is the general case, then value or sentiment transmits through an "if...then" by this rule:

X\Y      Good   Bad
Good  |  Good   Bad
Bad   |  Bad    Good

Interestingly this can be derived from Truism 4 - "Things remain the same." The stories about things remaining the same are positive and the ones where things change are negative.
Update: I am not sure if it this works in general. It may be because of the "like".
