Testing a Hypothesis Against the Record, Not the Reverse
Launch library · evergreen read

A working hypothesis is a useful starting point for research, giving a project direction and shape, but it becomes a genuine liability the moment a writer starts unconsciously selecting evidence to fit the hypothesis rather than testing the hypothesis honestly against whatever the record actually shows.
Building in deliberate checkpoints, moments where a writer explicitly asks whether the hypothesis still holds given everything found so far, helps catch this drift before it becomes deeply embedded in a draft that is already well underway and genuinely hard to unwind cleanly later on.
Being willing to abandon or substantially revise a hypothesis midway through a project, even after real investment in the original idea, is a genuine mark of disciplined research rather than a sign that the earlier work was somehow wasted or a personal failure. Framing the change this way, as the research doing exactly what it was supposed to do, makes it considerably easier to let go of an idea that no longer holds up.
