Reading a Source Against Its Own Bias
Launch library · evergreen read

Every source was created by someone with a purpose, an intended audience and a set of underlying assumptions, and none of that automatically disqualifies it from being useful. What matters is naming the bias openly rather than pretending a source is some neutral window onto the past.
Ask who benefited from the document being written the way it was, who it was intended to persuade at the time, and what it conveniently leaves out of the account altogether. Those questions do not discredit the source, they calibrate how much weight to place on any single claim within it.
A writer who does this openly, rather than silently in the background, produces work a reader can actually trust, because the reasoning behind each judgement stays visible on the page rather than simply assumed. It also models something valuable for the reader, showing that scepticism and trust are two parts of the same careful reading practice.
