Sorry guys, Mastadon didn't work for me. Find me on bluesky. @ulrichschimmack.bsky.social‬ ★ 1 Psychology often is unable to resolve disputes with empirical research. Structure of affect is one example. I wrote this review over 15 years ago. I think it is still relevant and the issues have not been resolved. https://replicationindex… ★ 6 #FalsePositiveRisk in #Medicine We provide an empirical test of Ioannidis's prediction and find the false discovery risk is well below 50%. Now as citation friendly preprint. https://arxiv.org/abs/2302.00774 ★ 9 #OpenData When the article states that the data are available on request and you ask for them. Thank you! We are still in the process of studying these data. Hence, unfortunately, I cannot give you an answer at present time. ★ 13 #NerdHumor #Statistics https://xkcd.com/2726/ ★ 17 Forget about your H-Index. What really matters is that you publish one article that makes a lasting contribution. Here Stroop who published only 4 papers. and has an H-Index of 4, but still 700 citations a year today. ★ 9 Now this is what I call junk science. https://psyarxiv.com/uy7ph/ ★ 11 An unfair disadvantage for German researchers. They now are forced to make their file drawers public. Every university could mandate this as part of IRB review. ★ 7 Happy New Year ★ 9 Happy New Year ★ 20 #PsychologicalDeception Despite the obvious replication crisis in psychology, psychologists lack a consensus about the cause. 1.
