Failure-mode index

Search what already failed

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.

Belief Bias in Individual and Collective Reasoning

Alba Massolo, Mariel Traversi, Matías Alfonso · 2024 · Europe's Journal of Psychology

In this paper, we investigate whether collaborative group performance is better than individual performance in solving a syllogism evaluation task. We hypothesise that collaborative group settings will outperform individual settings and that the belief bias effect will be mitigated in a group setting. Two empirical studies were conducted with Argentinian undergraduate students. Study 1 (N = 239) used a between-subjects design with two conditions: individual resolution and interactive group resolution. Overall, the group condition performed better than the individual condition, but there were n

EEffect of Chloroquine on Hyoscine-Induced Memory Impairment in Mice: Possible Involvement of Opioids and Nitric Oxide

Parsa Mohammadi, Elaheh Karimi, Adeleh Maleki et al. · 2022 · Acta Medica Iranica

Accumulating evidence suggests the potential use of chloroquine, an anti-malaria medication, as a neuroprotective agent. Moreover, several studies have reported that the endogenous opioids and nitric oxide (NO) may mediate the chloroquine’s effects. In the present study, effects of chloroquine on hyoscine-induced memory impairment were assessed. Furthermore, the possible involvements of opioids and NO were evaluated. Chloroquine was administered intraperitonially (i.p.) at doses of 0.1, 0.5, 1, 3, 10, and 20 mg/kg to hyoscine-treated (1mg/kg, i.p.) mice, and the spatial and fear memories were

Charlson comorbidity index has no incremental value for mortality risk prediction in nursing home residents with COVID-19 disease

Anum Zahra, Maarten van Smeden, Petra J. M. Elders et al. · 2025 · BMC Geriatrics

Abstract Background During the COVID-19 pandemic, nursing home (NH) residents faced the highest risk of severe COVID-19 disease and mortality. Due to their frailty status, comorbidity burden can serve as a useful predictive indicator of vulnerability in this frail population. However, the prognostic value of these cumulative comorbidity scores like the Charlson comorbidity index (CCI) remained unclear in this population. We evaluated the incremental predictive value of the CCI for predicting 28-day mortality in NH residents with COVID-19, compared to prediction using age and sex only. Methods
