I guess the learning phase of a science uses Si and Ti extensively, as in memorizing, understanding and analyzing the science in question. Ti works better on internally consistent and logical systems, and Si for irrational and random pieces of data. All sciences are slightly different combinations of the two. Psychology probably benefits from high Fi, Fe, and political science from Fe.
When the science and it's methods have been learned, I guess Ne might come handy in making the innovations, although the strict standards of scientific conduct must still be maintained (Ti and Si, for example). Ne seems to give the best heuristic to avoid dead ends with minimal effort and to be productive in a complex area of interest. Still, I think Ne provides the worst side-tracking from the studies in the learning phase, making it less likely for an Ne to earn a diploma

Ni I think comes handy in maintaining the interest long enough to finish the studies.
Te I think is very useful for both studying and practicing a science.
So I think it depends on those functions whether it's easy for person to earn the diploma and hard to make scientific discoveries after graduation, or vice versa.
Most types would find both tasks difficult.
