Whenever I meet something new or different, I always ask tons of questions, sometimes driving people up the wall. It's not that I'm not open to change, but because if I don't see any reason behind what I'm doing, I see no point in wasting my time do something at all. If it's a different way of doing something I've been doing all along, I need to be convinced as to its practicality and efficiency if it deals with tasks that requires results, through my own research or through other's explanations.
Sometimes, I look up solutions (ah, internet, how much I love you...) to everyday problems I encounter and get frustrated about. Like learning Colemak (keyboard configuration) and giving up on Qwerty because I failed to learn how to touch type on it even after years of using it. Sometimes I wonder if I'm addicted to things dealing with life hacks. Whenever there's something new that teaches you a simple way (or at least more efficient) of doing something, I'll go 'oh cool!' and jump right into it if time permits. I'm neither rebelling nor following traditions, I just go for what I think makes most sense to me.
Philosophy and school of thoughts wise, I do not discredit any as to me, it's just different ways of looking and understanding things. How can anyone be so sure that what they think is 100% 'right' and/or 'true'? I see relativity rather than definite 'quantities' for anything. I guess I enjoy learning how to look at things in many different view points as it means that there's more ways to classify things, etc, pretty much feeding Si's needs?
I would say that one of the main reasons why older SJs might come across as traditional is because they did not have access to all these information readily available to us, thus not using Si to its fullest potential as there's not enough info to begin with. And well, I do think that habits are hard to kick, no matter which type you are.
