The thing that keeps the franchise popular outside the Trekker cesspools is the engaging narrative focusing on the personal growth of the individual central characters, not the starship duels, laser shootouts, and technobabble. It's a show you can actually hold an intelligent philosophical discussion about, such as what we're doing in this thread. Here, we're discussing the central characters of The Next Generation, and how they place in the MBTI scale.
This discussion started with the OP's guesses, which they then admitted may have been incorrect. That was what I was referring to in my previous post, which I thought was made clear by the context of your post that I quoted.
Back to Worf, it is possible that he is ISFP, but tries to mask his Fe with his Klingon Ti. His insistence on wearing a Klingon baldric over his Starfleet uniform could be considered a visual interpretation of this.
As for Data, I prefer to type him as INTP, since he is very perfectionist about logic. Not so sure about after his emotions chip is install, since the subject was never given a lot of exploration. The novelty of having emotions overrode his obsession over logic in Generations, the chip was deactivated through most of First Contact, and both Insurrection and Nemesis pretty much ignored the chip's existence altogether.
