Basically I read or observe something (i.e., data collection). as I'm collecting data, my mind is noting what seems to be out of place with it, from (1) a perspective I think is logical and (2) from the model that the writer/communicator is using, a model I am replicating from their data as I proceed.
Everything gets tagged and noted. The processes are occurring simultaneously. meanwhile, another task is added to list -- my running assessment of potential issues with what is being contributed, what's wrong with it, and how it could be changed to potentially be correct.
Another task that is running is "Did I read this correctly?" where I'm trying alternate interpretations of the data I'm collecting to see if something there is coherent or whether those alternate interpretations also are faulty. (i.e., a checksum mechanism.)
Detail that I can't find a connection for in any of these processes is tossed as irrelevant, meaning i can then focus on the more relevant information. While this can occasionally lead to overlooking something, the payoff is that I can process much faster by "fuzzy logicking" with just the stuff that is relevant.
Again, it's all happening at once, I don't do it linearly, I'm multitasking from one task to the next and back through, and balancing it all in my head. What it takes in sheer processing power it provides in terms of large-scale coherence of the ideas being presented and what their flaws/strengths are in the big picture.
Which basically means I do really well with assimilating the gist of whatever I'm examining, understanding the framework being presented, and I do it fast. However, I can lose track of details (since I'm just focused on the concept the details represent and tend to just store the concepts long-term).
