Structuring Research Around Competing Explanations
Launch library · evergreen read

Rather than researching toward a single predetermined explanation, laying out every plausible competing explanation early and testing each one deliberately against the available evidence produces a more rigorous, more genuinely persuasive final account than chasing just one single theory right from the very earliest outset.
This approach also protects against the quiet trap of premature certainty, since holding multiple explanations open simultaneously keeps a writer actively looking for evidence that could distinguish between them, rather than passively accumulating support for whichever explanation simply arrived first in the whole research process.
When the evidence genuinely cannot settle between two or more explanations, presenting that honest uncertainty to the reader, rather than picking one arbitrarily for narrative convenience, respects both the reader and the actual limits of the evidence that was actually gathered. Readers generally respect this kind of honesty more than they respect a confident answer that later turns out to have been reached by quietly discarding an equally plausible alternative explanation.
