From what I vaugely remember of the SFDebris eps with Pulaski, the show runners wanted something like the relationship between Bones and Spock between her and Data.
They obviously failed miserably.
You could
tell that with Pulaski they were trying to recapture it, like Diana Muldaur was doing her best to play McCoy. She wasn't actually that bad at it, in my opinion, even if she didn't *nail* the role.
The biggest flaws in the concept, I think, were twofold.
(1) Data Can't Fight Back.
While Pulaski was at least
kinda sorta an approximation of McCoy, Data is about as unlike Spock as it's possible to get for two "left-brained" personalities. Spock was more or less content with his identity. Sure, he felt some conflicts between his Vulcan and human aspects, and just
having a Vulcan aspect generates some internal conflict. But for all that, Spock didn't feel inferior to humans, didn't consider being Vulcan to be somehow inadequate or lesser than being human. And he had a solidly developed, mature, confident personality. As a result, he was comfortable trading shots with people who made fun of him. So McCoy could twit Spock about being too gosh-darn left-brained, and Spock would twit
right back about how 'illogical' and foolish McCoy was sometimes.
But Data doesn't retaliate in situations like this, because Data has a Pinocchio complex. He thinks he's a fake simulacrum and
wants to be human, in a way Spock never did. On some level Data seems to have internalized that to be a robot is lower to being a human, that his uniqueness is lesser and inferior than that of the humans around him. When Pulaski basically straight up says to Data "I'm sorry, but you can never be as good as us human beings because you're a soulless dead automaton..." Data, on some level, just sighs internally and agrees. He doesn't try to retaliate. He seldom or never twits Pulaski (or anyone else) for oversimplifying things, neglecting the importance of calculation and planning, et cetera. He
can't, because he's got no sense of humor! Plus he's so generally kind to people (insofar as he knows how to be) that he wouldn't make fun of people even if he knew how to do it.
As a result, the Pulaski-Data interaction, unlike the McCoy-Spock interaction, doesn't come across as "right-brained" doctor and "left-brained" science officer poking fun at each other's foibles and limitations. It comes across as Pulaski bullying Data for being a nerd, and Data being too nice and not having enough self-esteem to push back.
(2) Strawman Syndrome
It's pretty clear that the TOS writers wanted it to be possible to sympathize with both sides in the McCoy-Spock feud. Spock genuinely makes mistakes and overlooks things because of his emotionless logical approach to life,
and he's not always sympathetic. McCoy, while often wrong, is almost always sympathetically wrong. "Dammit Jim, you
can't [insert thing that they have to do for the greater good here]! It's wrong!" is a somewhat compelling stance for a man to take, after all.
Enough of Spock's zingers back to McCoy are gratuitously insulting or seem... flawed... that while you can very much respect Spock's great intellect and measured approach to life, it's obvious he doesn't know everything and isn't right about everything in his relationship with McCoy. When McCoy gets in the last word, you feel like laughing. Conversely, the McCoy-Spock debates aren't
obviously an attempt by the writers to talk up the importance of dry formal logic by creating a strawman parody CMO whose asinine denunciations of logic make you think logic is the best thing ever.
By contrast, the position of the TNG writers was
always very obviously, and justly, that Data is a real person just like anyone else. Because they seem to have pretty well internalized this, even if they'd occasionally talk up how Data 'has no feelings' or something, they seem to have had a lot of trouble creating a sympathetic and realistic portrayal of the other point of view. It reminds me of a well-known passage from G. K. Chesterton's
The Man Who Was Thursday, describing an anarchist who tries to impersonate highly placed people in conservative society, but only knows how to do so by mouthing the strawman parody arguments in the anarchists' own propaganda.
G. K. Chesterton said:
"The answer is simple," he said. "I told you I was a serious anarchist, and you did not believe me. Nor do they believe me. Unless I took them into this infernal room they would not believe me."
Syme smoked thoughtfully, and looked at him with interest. Gregory went on.
"The history of the thing might amuse you," he said. "When first I became one of the New Anarchists I tried all kinds of respectable disguises. I dressed up as a bishop. I read up all about bishops in our anarchist pamphlets, in Superstition the Vampire and Priests of Prey. I certainly understood from them that bishops are strange and terrible old men keeping a cruel secret from mankind. I was misinformed. When on my first appearing in episcopal gaiters in a drawing-room I cried out in a voice of thunder, 'Down! down! presumptuous human reason!' they found out in some way that I was not a bishop at all. I was nabbed at once. Then I made up as a millionaire; but I defended Capital with so much intelligence that a fool could see that I was quite poor. Then I tried being a major. Now I am a humanitarian myself, but I have, I hope, enough intellectual breadth to understand the position of those who, like Nietzsche, admire violence—the proud, mad war of Nature and all that, you know. I threw myself into the major. I drew my sword and waved it constantly. I called out 'Blood!' abstractedly, like a man calling for wine. I often said, 'Let the weak perish; it is the Law.' Well, well, it seems majors don't do this. I was nabbed again. At last I went in despair..."
Basically, it
really shows that the TNG writers think Pulaski is wrong. They give her terrible-sounding arguments, make her say gratuitously nasty things to Data (see (1)), and basically never give her any way to substantiate her fixed belief that Data, as a robot, is an inferior form of being. She's a strawman on this issue, and it cripples her character.
I mean, Diana Muldaur is a good actress. It would have been well within her powers to make sure that Pulaski was lastingly remembered as the "cool old lady CMO" in contrast to Crusher's equally memorable "briskly professional middle-aged CMO."
But instead, most people who think of Pulaski at all think of her as "that horrible old woman who kept bullying Data for no damn reason."
