Case for omitting tied observations in the two-sample t-test and the Wilcoxon-Mann-Whitney Test. [PDF]
PLoS One, 2018 When the distributional assumptions for a t-test are not met, the default position of many analysts is to resort to a rank-based test, such as the Wilcoxon-Mann-Whitney Test to compare the difference in means between two samples.

Why Psychologists Should by Default Use Welch’s t-test Instead of Student’s t-test
International Review of Social Psychology, 2017 When comparing two independent groups, psychology researchers commonly use Student’s 't'-tests. Assumptions of normality and homogeneity of variance underlie this test. More often than not, when these conditions are not met, Student’s 't'-test can be severely biased and lead to invalid statistical inferences.

Model-averaged Bayesian t tests
Psychonomic Bulletin & Review, 2022 Abstract One of the most common statistical analyses in experimental psychology concerns the comparison of two means using the frequentist t test. However, frequentist t tests do not quantify evidence and require various assumption tests. Recently, popularized Bayesian t tests do quantify evidence, but these were developed for scenarios where
