“Voodoo” Science in Neuroimaging: How a Controversy Transformed into a Crisis
Social Sciences, 2022 Since the 1990s, functional magnetic resonance imaging (fMRI) techniques have continued to advance, which has led researchers and non specialists alike to regard this technique as infallible.

Modification of episodic memories by novel learning: a failed replication study
European Journal of Psychotraumatology, 2017 Background: After reactivation, memories can become unstable and sensitive to modification before they are restored into long-term memory. Using behavioural manipulations, reactivated memories may be disrupted via the mechanism of interference (i.e ...

A Systematic Review of Diagnostic Biomarkers of COPD Exacerbation. [PDF]
PLoS ONE, 2016 The aims of this systematic review were to determine which blood-based molecules have been evaluated as possible biomarkers to diagnose chronic obstructive pulmonary disease (COPD) exacerbations (AECOPD) and to ascertain the quality of these biomarker ...

Mendelian randomization study of causal link from gut microbiota to colorectal cancer
BMC Cancer, 2022 Recent studies have shown the relevance of gut microbiota in the occurrence and development of colorectal cancer (CRC), but the causal relationship remains unclear in the human population. The present study aims to assess the causal relationship from the

A statistical analysis of nanocavities replication applied to injection moulding [PDF]
International Communications in Heat and Mass Transfer, 2017 The purpose of this paper is to investigate both theoretically and experimentally how nanocavities are replicated in the injection moulding manufacturing process. The objective is to obtain a methodology for efficiently replicate nanocavities. From the theoretical point of view, simulations are carried out using a submodeling approach combining ...

Power Calculations for Replication Studies [PDF]
Statistical Science. 2022;37:369 -- 379, 2020 The reproducibility crisis has led to an increasing number of replication studies being conducted. Sample sizes for replication studies are often calculated using conditional power based on the effect estimate from the original study. However, this approach is not well suited as it ignores the uncertainty of the original result.

Does it actually feel right? A replication attempt of the rounded price effect [PDF]
Royal Society Open Science, 2018 How does the roundedness of prices affect product evaluations? The ‘rounded price effect’ postulates that depending on the context, rounded or non-rounded prices increase the purchase likelihood of consumers.

Frontiers in Psychiatry, 2023 A core principle in the pursuit of scientific knowledge is that science is self-correcting and that important results should be replicable. Hypotheses need to be reinforced, adjusted, or rejected when novel results are obtained.

The sceptical Bayes factor for the assessment of replication success [PDF]
, 2020 Replication studies are increasingly conducted but there is no established statistical criterion for replication success. We propose a novel approach combining reverse-Bayes analysis with Bayesian hypothesis testing: a sceptical prior is determined for the effect size such that the original finding is no longer convincing in terms of a Bayes factor ...
