you seem to look at functions purely on what some website states from them instead of looking at real life examples and reasons behind the real life examples. Te users dont only seek information on whats useful, my intj friend is interested on all kinds of useless information, like dark matter, black holes, gravitational forces and pretty much every science thing. Ti is more interested on how things work, instead of just collecting information. collecting information is food for Pi function(food supply comes from Je(with Te it means collecting facts from external sources)), trying to figure things out is food for Ji(food supply comes from Pe(with Ne it means trying to see the big picture)).
I don't see how you can do one without the other when typing fictional characters. If someone is acting in correspondance with a function definition, then they are using that function (or on some occasions, a combnation of functions that appears similar to it), as a definition is just what something is. My understanding of the functions is probably not entirely perfect, but I have got them from a variety of sources and discussions. You can't look for a real life example of something that you don't know what is. It is not to say that everything a Te user knows has practical value, but they do not see information as an end in itself, like Sheldon does. Ti DOES look for information as long as it finds it interesting. Te is objective reasoning, taking things in mostly on their practical value and forming connections between observable evidence. Ti is subjective reasoning, and therefore makes it's own assertions on what is important to know, and values theoretical deduction over observable fact. Therefore when the INTP has the Ti judging value and the Si wanting to memorise information, they often become enormous banks of knowledge, because they find something subjectively appealing. In fact, it's something INTPs are well known for. Ti-Ne wants truth, accuracy, ideas, information. Here is one example of subjective logic.
http://www.youtube.com/watch?v=prafMmD_mx8 - Here he makes a deduction based on logic, but does not feel any need to verify it with evidence. He has 100% confidence that he is right. Even a sensible Ti user would have enough practicality to know you can't make that assumption, and in fact Raj does this, while Sheldon is simply happy with his theory and confident that his deductions have been correct because it is logically likely. You still haven't explained why an Si user would be so interested in complex theory and hypothetical situations, and do complex scientific experiments. Remember when they were discussing how Superman cleans his suit? In such situations as this he even manages to avoid the need for certain conventional logic, diving into a theoretical world where certain parameters are altered and redefined from the reality yet it is still defined by logic and the logical implications of everything. He doesn't do this sort of theory for any reason. He just does it BECAUSEHE LIKES IT.
Te user might see a point of looking at whiteboard all day and trying to fit the known information to hypothetical information. this is a fine example where you are going wrong with you arguments. you try to fit sheldon into intp category by assuming that he is trying to pin point a logical inconsistency on the board, while he might as well trying to fit hypothetical facts into known facts by calculating. you are doing the same thing on pretty much all arguments(that is when you arent just using false information on functions and trying to fit sheldon into intp category like that).
I'm not trying to fit him in. I think he fits in much better and I'm trying to prove it. And yes, it is possible for a Te user to do this, but seems much more of a Ti Ne sort of thing.
sheldon has no understanding at things like irony or sarcasm, he cant even recognize if a person is in pain or sad by looking at him. former suggests really strongly to Te + nonexistent Ne and latter for nonexistent Fe and really low Fi. this would suggest him being an estj
metaphors can come from tert Ne
Okay, so now he's an ESTJ and not ISTJ? Also, not all INTPs can notice sarcasm. We only have inferior Fe, no Se, as well as Ti and Si, and thus we are often oblivious to things around us. It should be pointed out that Sheldon DOES understand sarcasm as a theoretical concept, but is very inadept at noticing when it is used.
yes. you do know how thinking behind the ocd works, right?
I have been taught that OCD is a compulsion to engage repeatedly in unnecessary and pointless behaviour on a regular basis and they can not feel comfortable if they don't. I apologise if I have been taught wrong, though.
P function isnt practical at all, it only gathers information. Ne would try to gather all different possibilities and constantly seek new ways of doing thing(this is why P(in type) is translated into spontaneous in finnish). If Ne is stronger than Si on a person, the person would have no problem of using the new ways over the old ways. If Si is the stronger P function, the person would get stuck into doing things the old way.
That's not necessarily true all the time, and in INTPs the Ti is in control of the Ne, and is thus more cautious. Also, I've said Sheldon probably has strong Si. But I've also said it's not unknown for him to experiment simply out of curiousity.
are you sure that this statement isnt just one of your false assumptions?
In a way that is "the most effective way of doing something" I'll admit, but in other ways it is really rather impractical, at least in the first one, as it's a lot of effort for little reward. In both cases though, it is merely for his own comfort and ideal sensory experiences which strikes me as Se at least as much as Te (though that doesn't play a terribly large role as neither types under discussion have Se and he shows little of it elsewhere).
one thing you should remember when discussing about types of fictional characters is that they are fictional and the person who invented the character most likely knows nothing about mbti and is just trying to build a funny character. and when discussing some fictional characters type, its all about what type is the character closest. yes sheldon might show some signs of an intp, but is you look at the big picture you will see a Te user.
On the first statement, I agree. He is fictional, not always entirely consistent and if he were real, I expect he would have a rather unusual function order score, which is probably why he is what most would deem "Unhealthy". He is unlikely to fit perfectly cleanly into any type. I also agree on the second statement. However, I disagree on the third. I think he shows some SURFACE signs of a Te user such as organisation of his external world, some extent of relying on observable knowledge and... (What else was there?), but if you look deeper you can see he has more traits in common with Ti-Ne users such as a desire for information and ideas for their own sake, a strict conformity to rigid logic, valueing his opinions more because he has reached them through logical deduction even if he lacks observable evidence, focusing on theoretcal topics etc.
