Yeah, I mean what is "moral" anyway? Doing what you believe is right?
So it doesn't even matter whether your morals emulate the conventional wisdom, you still have some.
(For example, I would consider "intellectual honesty" to be a typical moral for INTPs.)
So I think the question is vague and misleading as proposed.
That being said, @Staffan
's comments seem right on... I think that Thinkers are more likely to "deduce" their morals from information; the information changes, the moral will change. Feelers are actually keying off something internal to themselves and when that anchor changes, the moral changes, and external information can be ignored if the inner moral compass is still firmly valuing what it has always valued.
For my morals, I typically try to:
1. Keep my promises even at my own expense.
2. Retain intellectual honesty regardless of my feelings.
3. Be open to other people and their experiences, without simply writing them off.
4. Treat other people with dignity rather than dehumanizing them.
But these are broad philanthropical morals, rather than "don't lie, don't drink, don't murder, don't swear, etc." or uttering words like, "Well, I don't do THAT."
