The interpretation that I find the most intuitive puts them the wrong way round, to the point where I remember which is which by specifically remembering "it's the opposite of what you'd think".
And at that point I usually look it up in wikipedia or on my left arm, because I'm not sure anymore
Every time I try to use a “it’s the opposite of what you think” mental shorthand, I get used to the wrong-seeming (but correct) way it is, and then I start mentally flipping it back to the actually incorrect version.
