Failed Experiment Report·Chemistry & Materials
Chen, W., Martinez, J., Liu, H.
We report an unsuccessful attempt to synthesize room-temperature superconductors using a novel nitrogen-doping approach in copper oxide lattices. Despite promising theoretical predictions, experimental results showed no superconducting transition above 40K.
Negative Results Report·Social Sciences
Thompson, A., Wang, Y.
This pre-registered randomized controlled trial (n=450) found no statistically significant effect of an 8-week mindfulness program on measured workplace productivity metrics (p=0.78, 95% CI: -0.12 to 0.15).
Replication Failure·Computer Science & AI
Park, S., Müller, F., Johnson, R.
Despite following the exact methodology described in the original paper, we were unable to replicate the reported 94.2% accuracy, achieving only 87.1% with identical hyperparameters across 5 independent runs.
Method/Design Error·Life Sciences & Biotechnology
Nakamura, K., Okonkwo, E., Santos, M.
Our field trials demonstrate that humidity levels above 85% significantly reduce gene drive efficiency by 73%, making this approach impractical for tropical regions where vector control is most needed.
Abandoned Hypothesis·Social Sciences
García, L., Kim, S.
After three years of research, we conclude that our proposed extension of cognitive load theory does not adequately explain multimedia learning patterns in populations aged 65+. Key predictions failed in 7 of 9 experiments.
Null Dataset·Medicine & Public Health
Pharmaceutical Research Consortium
We release data on 15,000 compounds that showed no significant inhibition (<10%) of SARS-CoV-2 Mpro in our high-throughput screening campaign, to prevent duplication of screening efforts.
