A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.
WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Introduction Problematic social media use (PSMU) and caffeine use disorder (CUD), a behavioral pattern without formal diagnostic status and a DSM-5 condition listed for further study, respectively, share phenomenological features…
Marshev V, Frey HG, Brascamp J · 2025 · Journal of vision
The pupil constricts in response to visual stimuli that keep net luminance unchanged but that do introduce local luminance increments and decrements-a reaction here called "isoluminant constriction." This response can form a pupillometric…
Tammurello C, Coelho LA, Amadeo M et al. · 2026 · Scientific reports
In the Somatic Rubber Hand Illusion (SRHI), synchronous brushing of a participant’s hidden hand and a dummy hand induces proprioceptive drift, a shift in perceived position of the hand towards the dummy hand, along with the sensation of…
Sasidharan S, Philips CA, Philips CA et al. · 2026 · Hepatology communications
Background Fatigue affects 60%-80% of patients with cirrhosis, yet no universally effective pharmacologic therapy exists. Taurine, an amino sulfonic acid with antioxidant and membrane-stabilizing properties, may address metabolic…
