The above diagram is inaccurate. Sufficient conditions are not necessarily necessary. For example, there may be a university course where certain exam results are sufficient to gain entry, but mature students do not need these results.
I admit that it was crude, but I believe it has some merit.
Fictional example:
You *can* pass a course by getting a grade of C or higher (but other factors will be considered). You *will*, however, pass a course by getting an A. Here, S (an A) is a subset of N (C or higher).
The "mature student" claim introduces an additional variable. If you focus solely on the students who do not meet the "mature" criteria, my logic holds...
Ok, after doing some searches on the Internet, I believe I have identified the source of disagreement.
The "sufficiency" concept simply has different meanings.
Apparently, it is either:
1. A subset of necessity (B only if A + If A, then B)
2. An independent construct (If A, then B - Which does not exclude: If Some Non-A, then B)
I guess things get lost in translation...
