I’m not debating. It is not a matter of opinion. I’m doing you the courtesy of informing you how the entire rest of the world uses the term.
If action A looks for thing X, and it finds thing X, then the test is positive. If action A fails to find thing X, then the test is negative.
If action A claims to find thing X, but later confirmation determines that thing X is not really there, then this situation is called “false positive”.
If action A claims fails to find thing X, but later confirmation determines that thing X is actually there, then this situation is called “false negative”.
That thing X may subjectively be considered an unwanted outcome has **nothing ** to do with the terms used.
