what matters now
read: posner & petersen 1990

classic three-network model. their "alerting" maps onto what i have been calling baseline arousal. the disagreement i care about: is alerting separable from orienting.

↗ pinned
alerting and orienting dissociate under load. the hinge for ch.3.
today is one paper. pin the claim that matters. the rest stays in memory.

the argument, in one scroll

pin × trail. every claim you kept, with the tables, diagrams, and sources beside it.

why not a reference manager

a reference manager stores what you read. it cannot store what you thought about it, because the thinking happened somewhere else: in a margin, in a different app, or not at all. a notes app stores the thinking and then buries it under everything else you typed that term.

the pins on a topic trail are the claims you judged worth keeping, in the order you met them, with the tables, figures, and sources still attached to each one. that is a literature review with the reasoning intact rather than a bibliography with a summary bolted on afterwards.

and the reading days themselves stay in memory rather than following you forward. they are supposed to. most of what you write while working through a paper is you arguing with it, which is the work, not the output.
