No classification is better or worse than any other, questions. Fear not!

Here's what Wikipedia says, FWIW:

Quote
Myers and Briggs taught that types ending in J show the world their Judging function - either T or F. So TJ types tend to appear to the world as logical, and FJ types as empathetic. According to Myers[2], Judging types prefer to have matters settled.

Those types ending in P show the world their Perceiving function - either S or N. So SP types tend to appear to the world as concrete, and NP types as abstract. According to Myers[2], Perceiving types prefer to keep matters open.

Does that help at all?
