There is nothing wrong with randomness (though I don't quite believe in the purely random) ...
Briefly:
I (and you and everyone else) have a specific worldview, a framework through which we analyse the incoming data. Some people are just more ..let's say
comfortable.. with challanging their own frameworks. Some aren't and stay 'true' to their (or their parents') frameworks, even though it's been proven inconsistent many years ago. Well, some people go for the truth even though it causes constant inner chaos, others go for inner stability, even though it might cause them to never reach the ultimate truth (if that even exists [it has to]). In both cases it's all about comfort. Even though you say it's annoying to spend 10 minutes writing
one line, it's still more comfortable for you doing so than not doing so. (?)
In any case, the framework might be very off, but you might not know that, right? - and since Ti looks for consistancy and universal truths (inner data has to make logical sense and fit together neetly, otherwise the system crashes and general anxiety kicks in

), Ne constantly searches for random (which isn't that random) info to constantly challange the framework. It could be that you'll spend three days with random wiki research, and youtube documentaries, and you'll learn a bunch of "random" things but nothing has really changed for you, your framework has allowed all the info to pass through without an error-warning --- but on the forth day you'll stumble upon a piece of information that'll make you go: wooh, wait a second, is that really true? Yes it seems to. But wait, it doesn't fit into the framework, which means the framework is wrong!
Then the inner chaos awakens (it's actually a really cool feeling, knowing that you have to adjust or even totally remake your framework based on the new info, because...well, it feels almost like moving to a new era, literally seeing the world in a totally different way, even though the adjustment is very small {think of Sudoku, changing just one number in the pattern changes the pattern slightly, but all-around the pattern}. -- And if a whole new framework-remake is necessary, well that's like moving into a cool new apartment that you can furnish from the ground up. This can take days, weeks, even months - and is a very awesome process [if you ask me]).
And yes, I love brackets.
