Introverted Sensing: the reason we are in the SJ forum. My question is: How do you use Si? Basically, I'm addressing mostly SJ's here, but feel free to answer even if you're not SJ.
I'll start off -
Si is my leading function, has been for a long time. The way I use it is... let's say I see something - just anything - like... a tree, for example. When I look at the tree, I automatically think of any past associations I've had with that tree (my brain does this instantly, without me even thinking about it). Basically, it's like a built-in evolutionary instinct to find if I should continue with an activity that I have done in the past, or whether I shouldn't.
Si for me can both be a blessing, as well as a curse. For example, if I have a job to do, before doing the job, I think of whether I have done this before. If the answer is yes, I think of what the performance was like last time I did. If it was good, then it sort of encourages me to do the activity. If it was bad, then it sort of discourages me a little. But when this happens, I usually tend to find the positives of doing the job.
This is sort of why change, for me, is difficult. Because if I encounter a different situation, then I cannot relate it to anything in the past (since it was not part of my past). Therefore, the potential environmental and impact dangers are apparent to me for new situations.
Another way I use Si is when I see or hear something, it can just stick in my mind, even sometimes for several years. If I force myself, I can capture a mental photograph of something and reproduce the same picture a short while later too. And of course, Si helps me in remembering any kinds of interesting facts or data.
Anyway, how about the other SJs - how exactly do you use Si?
