hmmm
Your temporal lobe processes many of these things, but not by itself.
Both hemispheres work with each other and communicate ideas to you during the emotional and analytical data your brain is trying to understand - these ideas are lightbulb moments.
Imagine your emotional reasoning is making your analytical thought process lag behind and it can't quickly catch up.
I don't know what's going on inside my brain when my gut instinct on scum reads. They appear random because the ability to explain the logistics behind scumreads is still being processed. My brain and your brain pick up little pieces that form scum reads via behavioral pattern identification. You (your brain) later simplifies it as common sense, leaving the little details the brain (language usage, general idea of a user's scumplay, how they react to posts, what they're trying to do with the lynch) picks out.
For me, I do eventually simplify it (most people do this without feeling it's necessary to go over the details) but my brain interprets this as a threat, so what I wind up doing (consciously) is an avoidance of trusting my strongest town reads.
In a sense, I do things backwards. It's why I had such a hard time bringing myself out of the tinfoils because the gut instincts were based on not refusing to let my guard down, creating a tsunami of paranoia as a result.
The majority of you aside from Flower don't struggle with this, because you have a better grasp on who to trust and who not to.
