You could say that.
You take a personality test (short one) and you type as something. You look at adjacent personality types (one or two letters apart), and list the ones that fit you even partially. Your personality type is the one that has the minimum "distance" from all the other types.
Quick example: you type ISTP. You look up a bunch of types, and smack on your list: ISTP, ENTP, INTP, INTJ. Note how INTP is one letter different from all the others on the list, where as the others have two letters of difference with at least one other (INTJ-ISTP). Therefore, the type with the minimum (additive) distance is INTP and that is your type.
Btw, I didn't read this anywhere, it's just my thinking.
