Have I mentioned how I dislike the use of "mental model" for this type of post?

Or how X=Y+Z is misleading (set Z to zero, and you still have X). From post: " Behavior = motivation + ability + trigger...

According to FBM, there are three things we need to do something:

    Motivation
    Ability
    Trigger"

No, addition doesn't mean "You need all three". Multiplication does. B=MAT.

AND = multiply

OR = add.
