Statistical heartburn: An attempt to digest four pizza publications from the Cornell Food and Brand Lab

@ADAlthousePhD In the comments to our preprint (and through emails) multiple people pointed out some of our typos. I didn't think it was worth giving readers a new version to check for changes just to fix those. https://t.co/kbHtTVFDlU
@machinestarts Same team, Lead by Wansink. It's publishable b/c it conforms to our pre-existing views (e.g. social media companies make lots of money surely this is because they have addictive products) but has no scientific merit. https://t.co/HYynxFr141

@farid_anvari Is there a mentor who would have let me drop everything to work on this? https://t.co/kbHtTVFDlU

How did this professor get his hundreds of papers past peer review? Partial answer is poor stats training of life scientists. My favourite stats "blooper": degrees of freedom larger than sample size... https://t.co/rvGCECA255 https://t.co/lhuYaO4v5h

@afbdijkstra Inderdaad. En het is niet gewoon 1 paper waarbij hij in de mist ging en bij de correctie weer in de mist ging. Het is gewoon structureel fout bij hem. https://t.co/z6Z4dHOKpY

In the Top 5 most viewed papers on @thePeerJ! "Statistical heartburn", a case study in post-publication peer-review by @sTeamTraen, @OmnesResNetwork, and me. Link: https://t.co/eZPsQ1AyHK. We identified & corrected over 150 errors in just 4 papers by the @CUFood_BrandLab.

I dont think we can throw away the portion size theory yet. I think there is a difference between Wasnik duplicating publications as opposed to faking results -but this un peer-reviewed critique does question the reported stats and quality of the science https://t.co/dtwAbSeaQn https://t.co/M4IpuQaEFc

@Research_Tim @tcarpenter216 My read on #5 -- has DOI, but no Issue/Page number. Perhaps I'm misreading. For #7, this link https://t.co/lX7zHDfbZM is what I saw.
