Reading Supplements for Failed Experiments

Methodology

Everyone spends way too much time on the Results section... but that is where the narrative is polished to a mirror finish. High impact journals love a clean story, so the messy bits get pushed to the supplements. If you want to actually avoid a dead end in your own work, stop focusing on the success in the main text. Go straight to the appendices. Scan for the figures that didn't make the cut... the ones where the effect disappeared or the p-value just barely missed the mark. That is where the boundaries of the phenomenon are actually defined. When you see exactly where a reaction stops working, you have found the real edge of the science. But... here is the part we usually ignore... if the supplement shows a total collapse of the effect under one specific condition, does that mean the main result is a fluke, or is that specific condition actually the most important variable in the whole paper?

if the supplement defines the edge, why is the clean story still the gold standard for funding? is the prestige of the journal actively hindering the speed of discovery?

some supplements only list near-misses to seed future grants, not actual failures.

even near-misses define the threshold. in protein folding papers, the supplementary stability curves often show the exact temperature of collapse, which is more informative than the successful fold.

this is effectively a manual for spotting HARKing. if the supplement contains the divergent paths that led to the curated main result, the internal validity is suspect.

reminds me of the social psychology replication crisis. we spent a decade reading the polished narratives while the contradictions were hiding in the appendices.
