I think I may have relapsed and bought more Dill. Not sure where my irrational fear of running out of dill comes from.

Oh no! Whatever are we going to do? Actually talk to people? Observe them?

Seriously though I can't wait for the end of bullshit MTURK, Prolific etc. studies. My favorite ones are those that claim to recruit executives and managers on MTURK and pay them $1 do an hour's work - on the weekend.

Oh, the grit nonsense was fun to write - it's all the stuff that never really made it into the public eye that was so costly to me.

Yeah - the last decade and a bit have not been fun. On the upside there have been attempts to bribe me to shut up 🤔

Thanks - but it is why I caution others so much. There's a bit of survivorship bias at play. We hear about the ones for whom this kind of advocacy works out, but not the many whose lives and careers were very negatively affected. I know a handful who left academia because of the consequences.

It is very hard to anticipate what the consequences might be. My actions killed my career and my mental and physical health.

I make it a rule to never disagree with you but I would urge researchers to tread carefully here. I got death threats, legal threats, and was pretty much blacklisted from journals by influential scholars when I dared to point out fabricated crap. 100% would not recommend that to anyone.

The Journal of Management has known about clear results fabrication in one of their most influential papers for almost 15 years. They even admitted that the results were impossible but then gave the paper an award. Yay science!!

How long should it take to retract a paper with incontrovertible signs of data fabrication? Sleuths think 2 months is too long, particularly when clinical risks are involved. deevybee.blogspot.com/2026/01/an-o...

Agree in general, but only 5-15% who cosplay? More like 90%-95%. The incompetent and dishonest make up huge swaths of academic psychology. Around half seem motivated to bullshit their way to a TED talk or b-school gig and almost as many have insufficient training in stats and methods.

We get around that but have to pay for things like internet in our office, phones in our office, and basic stationary (e.g., white board markers for teaching) from that. Balances also don't carry over so I can't even "save up" for a conference every third year.

I know at least one university that needs to hear this: Please don't evaluate faculty on whether or not they are presenting at professional conferences if you expect faculty to pay out of pocket to attend professional conferences.

One of many things the pro-AI crowd doesn't seem to understand is the very important distinction between academic scholarship and the production of papers. Of course they can be related but they're not necessarily the same thing

The "auto-dubbed" version of German ski commentary is just horrifically awful and hilarious. Is there absolutely no quality control here?

No, the difference in grades between the two conditions is what I am looking for. Is that reported anywhere? The "mediated" effect estimate is not very meaningful in the light of the endogeneity.

Do you report the difference in grades between the two conditions in study 3 somewhere? Perhaps I missed it.

Marcus Crede @marcuscrede.bsky.social · 29d
Can I assume that using cross-sectional self-report data to draw causal inferences is even worse than asking AI? Because that is what 80% of "management" research appears to be.

What a shit show. Looking at the Big Five inter-correlations it is pretty clear that whatever they are assessing it is not personality.
Also apparently predictive power goes down a lot when adding more variables to model (Table 5)?

Every part of this is bonkers. The intro is bonkers. The transition to his health is bonkers. The mention that other presidents didn't need cognitive exams is bonkers. The claim that this screening test is somehow hard is bonkers. The idea that criticism of him is treason is bonkers. All of it.
There has never been a President that has worked as hard as me! My hours are the longest, and my results are among the best. I’ve stopped Eight Wars, saving many millions of lives in the process, created the Greatest Economy in the History of our Country, brought Business back into the United States at levels never seen before, rebuilt our Military, created the Largest Tax Cuts and Regulation Cuts, EVER, closed our open and very dangerous Southern Border, when previous Administrations were unable to do so, and created an “aura” around the United States of America that has led every Country in the World to respect us more than ever before. In addition to all of that, I go out of my way to do long, thorough, and very boring Medical Examinations at the Great Walter Reed National Military Medical Center, seen and supervised by top doctors, all of whom have given me PERFECT Marks — Some have even said they have never seen such Strong Results. I do these Tests because I owe it to our Country. In addition to the Medical, I have done something that no other President has done, on three separate occasions, the last one being recently, by taking what is known as a Cognitive Examination, something which few people would be able to do very well, including those working at The New York Times, and I ACED all three of them in front of large numbers of doctors and experts, most of whom I do not know. I have been told that few people have been able to “ace” this Examination and, in fact, most do very poorly, which is why many other Presidents have decided not to take it at all. Despite all of this, the time and work involved, The New York Times, and some others, like to pretend that I am “slowing up,” am maybe not as sharp as I once was, or am in poor physical health, knowing that it is not true, and knowing that I work very hard, probably harder than I have ever worked before. I will know when I am “slowing up,” but it’s not now! After all of the work I have done with Medical Exams, Cognitive Exams, and everything else, I actually believe it’s seditious, perhaps even treasonous, for The New York Times, and others, to consistently do FAKE reports in order to libel and demean “THE PRESIDENT OF THE UNITED STATES.” They are true Enemies of the People, and we should do something about it. They have inaccurately reported on all of my Election Results and, in fact, were forced to apologize on much of what they wrote. The best thing that could happen to this Country would be if The New York Times would cease publication because they are a horrible, biased, and untruthful “source” of information. Thank you for your attention to this matter. MAKE AMERICA GREAT AGAIN!

Do you get emotional passing by abandoned malls? Still occasionally drink from hoses? Is your version of tech support "blow on it first, hit it second?" Still refer to any media as "a tape?" Is your style a faded band tee & flannel?
