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.

Background: Bupropion (BUP) is a chiral antidepressant and smoking cessation aide with benefits and side effects correlated with parent and active metabolite concentrations. BUP is metabolized by CYP2B6, CYP2C19, and CYP3A4 to hydroxy-BUP…
Craig R. Miller, Anna C. Nagel, LuAnn Scott et al. · 2016 · PeerJ
Parallelism is important because it reveals how inherently stochastic adaptation is. Even as we come to better understand evolutionary forces, stochasticity limits how well we can predict evolutionary outcomes. Here we sought to quantify…
Ann Armstrong · 2024 · Equality, Diversity and Inclusion: An International Journal
Purpose I examine if current diversity, equity and inclusion (DEI) initiatives can actually accomplish what they aim and claim to do. I argue that perforce they cannot, as they remain instruments of capitalist corporations and other…
