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.

Objective Sexual minority (SM) populations experience worse cardiovascular health than heterosexual populations. One potential pathway is the effects of disclosure (sharing) or concealment (withholding) of SM identity due to anticipated…
Kweon J, Ganesh P, Brown JC · 2025 · Transcranial magnetic stimulation (2024)
Health and behavioral factors likely influence repetitive transcranial magnetic stimulation (rTMS) effectiveness, though clear support is lacking. Since habitual caffeine use has been found to impair corticomotor plasticity, we…
