This is true; also applicable to any Pi (Ni, Si) or Ji (Ti, Fi) function-attitude (fxn). In Jungian typology any introverted fxn is considered 'subjective', meaning that the subject apprehends a given stimulus more indirectly via an interrelational context emergent between them, ergo necessitating that a person outside of it become involved w/ said context in order to understand it. Whereas extroverted fxns tend to isolate and externalize things, conveying them in a more acontextual manner rendering greater communicative accessibility to 3rd parties.

If you delve into Information Aspects (IAs), Introverted/Extroverted fxns are synonymous with Field/Object IEs respectively (functions = IEs). Wrapping my brain around IAs was the best for boosting my understanding of the inherent differences between IEs. The 3 dyads comprising the suite of 8 IEs are as follows (my interpretation of each):

Explicit (E) - Something demonstrable. Regards stimulus directly, interpreting for sensorial qualities or extant facts.
Implicit (I) - Something inferred. Regards stimulus indirectly, interpreting for conceptual qualities or affective values.

Object (O) - Perspective is directed outside the self and towards the subject's appraisal of the stimulus.
Field (F) - Perspective is drawn inside the self and concerns the subject's interrelationship with the stimulus.

Static (S) - Discerns a stimulus in terms of fixed attributes, yielding cues to establish a given context, with particular respect to their separable distinctions.
Dynamic (D) - Discerns a stimulus in terms of mutable attributes, its changes with respect to a given context, as well its synthesis and interactions.

Each of these 6 parameters would refer to how a mind tends to experience, construe, and apperceive reality—in this way, each IE can be conceived as like a filter which 'colors' reality in different qualitative shades, analogous to say, how a prism can polarize the same light source into different chroma. The 8 combinations of the 6 IAs go like this:

Se: EOS (Explicit Object Statics)
Te: EOD (Explicit Object Dynamics)
Ti: EFS (Explicit Field Statics)
Si: EFD (Explicit Field Dynamics)
Ne: IOS (Implicit Object Statics)
Fe: IOD (Implicit Object Dynamics)
Fi: IFS (Implicit Field Statics)
Ni: IFD (Implicit Field Dynamics)

So, putting all this together, Ti (E+F+S) could be considered correspondent to something like "apperceiving phenomena in an explicative way via fixed subjective contextual frameworks"—aka, 'structural logic'. Whereas Ni (I+F+D) might be something like "apperception of emergent changes implied by evolving interrelations between phenomena"—aka, 'fluid intuition'. A key distinction between the two is going to be that Ti is more deliberately ratiocinative, while Ni is more incidental in nature and draws greatly from ambient perceptions.

I suspect much of this probably sounds like word garble right now, and there's a lot more I could say I'm sure. Ask clarifying questions if you'd like.
