"40 percent of MRI signals do not correspond to actual brain activity"; "Since tens of thousands of fMRI studies worldwide are based on this assumption, our results could lead to opposite interpretations in many of them.”

40 percent of MRI signals misinterpreted

Interpretation of numerous MRI data may be incorrect: blood flow is not a reliable indicator of brain activity.

Yikes!
“Increased oxygen consumption – for instance in areas involved in calculation – did not coincide with the expected rise in blood flow. …analyses showed that these regions met their additional energy demand by extracting more oxygen from the unchanged blood supply.”

Experimental evidence that students are more likely to contest grades when they are delivered by an evaluator with a female-sounding name.

"These findings suggest that women in evaluative positions face disproportionate resistance when delivering negative assessments."

This kind of argument is everywhere... link.springer.com/article/10.3...

Most evidence for the compensation account of cognitive training is unreliable - Memory & Cognition

Cognitive training and brain stimulation studies have suggested that human cognition, primarily working memory and attention control processes, can be enhanced. Some authors claim that gains (i.e., post-test minus pretest scores) from such interventions are unevenly distributed among people. The magnification account (expressed by the evangelical “who has will more be given”) predicts that the largest gains will be shown by the most cognitively efficient people, who will also be most effective in exploiting interventions. In contrast, the compensation account (“who has will less be given”) predicts that such people already perform at ceiling, so interventions will yield the largest gains in the least cognitively efficient people. Evidence for this latter account comes from reported negative correlations between the pretest and the training/stimulation gain. In this paper, with the use of mathematical derivations and simulation methods, we show that such correlations are pure statistical artifacts caused by the widely known methodological error called “regression to the mean”. Unfortunately, more advanced methods, such as alternative measures, linear models, and control groups do not guarantee correct assessment of the compensation effect either. The only correct method is to use direct modeling of correlations between latent true measures and gain. As to date no training/stimulation study has correctly used this method to provide evidence in favor of the compensation account, we must conclude that most (if not all) of the evidence should be considered inconclusive.

E-values (big E) quantify how strong an unmeasured confounder needs to be to fully explain away a causal effect. If the E-value is large, only a very powerful confounder could negate the finding, so the result is more robust. Think sensitivity analysis pubmed.ncbi.nlm.nih.gov/28693043/

Sensitivity analysis is useful in assessing how robust an association is to potential unmeasured or uncontrolled confounding.
