Theories and studies of risk preferences typically assume that the subjective value of an outcome is independent of its probability. In this paper osf.io/r6ebg (in press at Management Science) @andre_quentin and I questioned the validity of this assumption 1/2

@jpsimmon Very happy for you and for everyone.

Gino's case against us has been dismissed. Scientists cannot effectively sue other scientists for exposing fraud/errors in their work. Those who work to correct the scientific record can sleep better tonight. Those who don’t want it corrected, well, I don’t care how they sleep.

@OlegUrminsky Fantastic! Congratulations!

Selfie with the first issue of JCR that I ever read (September 2002):

@i_evangelidis @Prolific Hopefully it was a representative sample

@gpaolacci @Prolific I paid prolific participants to do it

yo @Prolific, you sent me 142 identical emails telling me that data collection for my study is complete. What's up?

Just had a paper sent back from a journal, about 2 hours after I submitted, because the footnotes were not in Times New Roman.

Hi Society for Judgment and Decision-Making appreciators! Let us know about your SJDM related announcements, conferences, and jobs by tagging @SJDM_Tweets in your tweets!

@andre_quentin One version of that argument is that tradeoff exists at researcher level--both rigor and relevance take effort, effort is zero-sum, so focus with rigor implies neglecting relevance. Not my take :-) "Rigor and Relevance" will be the theme of the Doc Symp at #ACR2024! @aconsres

Yes, in theory, it could be true that an impossibly high bar for rigor prevents us from studying rich, complex phenomenon. But this isn't the reality of social sciences these days. We're drowning in sloppy, low-quality research. We need fewer, and more rigorous, papers.

I must admit that I do not understand the so-called tension between rigor and relevance in consumer research. Isn't rigor is a sine qua non for relevance? How can research hope to inform policy and decision-making if it is not rigorous?

@annemscheel @ianhussey That's great. I've been long looking for a small exercise (ideally not requiring particular programming skills) to let people experience how degrees of freedom affect conclusions. I'd also love to learn more...

@ianhussey That's a brilliant exercise! Would it be possible to share your teaching materials/instructions?

A mini Many Analysts: I taught a masters course on data wrangling and visualisation in R+tidyverse. Given the same data and instructions for how to do exclusions, this is the distribution of sample sizes after exclusions that different students reported.

🚨 New in @PNASNews 🚨 We find that people see more of their #biases in #algorithms' decisions than in their own #decisions, even when algorithms are trained on their decisions and when those decisions are the same. 1/n pnas.org/doi/10.1073/pn…

@lakens Carmina Burana for when you circle p-values, John Coltrane when you're done

I have always wanted a record player in my office, so I bought one a few weeks ago, and it has been making my working days a lot more enjoyable. I do share an office with 3 others, so I mostly play it when I am by myself, but that happens often enough.

@MarijkeLeliveld right now he's likely showing a screenshot of your post and telling his classmates "told you this would happen, give me the money"

Woke up to the good news that our paper (w/ @nreinholtz) on group sequential designs is accepted at @JCRNEWS ! Want to learn more about designing more efficient and more informative studies? This blog post summarizes the key insights from our paper: quentinandre.net/post/more-effi…

Papers covered by @nytimes get cited more. Is that causal or just selection bias? Almost surely causal: papers that NYT *wanted* to cover but *didn't* because of a strike got cited similarly as unwanted (but equally prominent) papers nejm.org/doi/10.1056/NE…

Are you a PhD student in marketing at a European University? Submit your dissertation research to the 10th SIMktg Doctoral & Research Colloquium, the deadline is March 31 - More info: lnkd.in/d9VFKVfE @gpaolacci @real_k_diehl @chofack Ana Valenzuela Marco Visentin @SIMktg

@lakens @CameronBrick Until now I thought "very learned opponent" and "highly learned opponent" were interchangeable :-) I find the formality of PhD defense in the NL very funny (and surprising for the NL), and also defied by how many people in the room clearly find it funny.

@CameronBrick I agree, this specific part is a bit nonsense in 2024. I can tell you I messed it up during my defense (it was not high on my priority list to care about such stuff) but I still got my PhD :)

@ignaziano Someone probably meant to nominate Iganzio and they spelled it wrong

Who did this

@jayvanbavel @gavaruzzi @eRubaltelli We got the first rejection by some journal in the morning. We resubmitted it right away to Judgment and Decision-Making. @jonbaron1944 read it and desk rejected it in the afternoon--on very fair grounds and sharing actual comments. A mix of many emotions.

@gavaruzzi @gpaolacci @eRubaltelli Wow, how?

I had three papers rejected on Tuesday. That's a new record for me. What's yours? I realize people don't see all the rejection and constant negative feedback, just a string of successes. So here a downward social comparison for you :)

@silvia_saccardo @CarnegieMellon @CMU_DietrichHSS congrats!!

Officially tenured! @CarnegieMellon @CMU_DietrichHSS So excited and grateful! And this note from my 5-year-old made the day even more special 🥳

@Mario_Macis Dall-E revealing the invisible hand

I asked dall-e for a funny “hug an economist day” drawing (with a male economist with glasses) and what I got is 💯 PS: note that the guy has three hands! An economist’s dream being able to say “On the one hand…on the other hand..AND on the other hand” 😅

The subjective value of a prospective outcome should not depend on the likelihood it will occur, but @gpaolacci & @andre_quentin find people actually anticipate less utility from uncertain than from certain outcomes, even conditional on their realization: bit.ly/3OoxaZ6
