The anchoring effect has been one of the most far-reaching phenomena across the behavior sciences with a history spanning 50 years. Have you every been curious what we have learned over these decades? Take a look at our new preprint: psyarxiv.com/teq7k/

Plot for a B movie. The year is 2028. There is no sentient AI. But scientists have successfully applied transformer models to speak to Whales and Dolphins, who are, as suspected, highly intelligent. Everyone cheers. BUT [ominous music] 1/n

This is funny, but it showcases a common misconception of DAGs—the assumptions are the absence of arrows not their presence!

@Chanman_ECON @PaulaAureo The Schennach papers this is based on (referenced therein) are a bit more straightforward. This paper introduces a slack variable that I found a bit tricky to make work…

@PaulaAureo Thank you, Aureo! I was thinking something like EL, so this looks very interesting.

I'm looking for any recommendations on how to estimate the model parameters defined by moment conditions using Bayesian methods. Any references would be very appreciated!

It's job market season, and I received feedback from JM candidates that they are finding my 2021 "practical guide" still helpful today (and recommended to share it more widely...😇) Here it is: sites.google.com/view/martinapo… Good luck future colleagues, you are amazing!

Dear @stephanygj, please, for all the women and URM scholars in our profession, please ask your son to shut down EJMR/PSR/SJMR.

The anonymous hordes of EJMR have mercilessly abused countless people for more than a decade. Today it's time to show who is behind all the villainy. Kirk, the administrator of EJMR, is David Griffith-Jones as first reported by @jessuppi. ejmr.exposed

Fire ants who survived wrote about this end-of-times event in the fire ant sacred book. Later generations learnt piously about the shiny scalding water of God’s wrath. Many fire ants warn not to take this description literally.

@uri_sohn @andre_quentin @annemscheel I had the same thought (I use the same strategy) but I think the advantage of the methods described in the post is that it works when calling an external package’s code, and that code is spawning the threads…?

@andre_quentin @annemscheel I just set the seed inside the parallel loop as a function of loop number. Like this: set.seed(simk) Isn't that easier?

Very niche tweet: If you are running a parallel simulation (i.e., on multiple cores) in R, and you want it reproducible, setting a seed at the beginning won't do it! This website provides excellent resources on how to make it work: pat-s.me/reproducibilit…

Good unsolicited advice that should be solicited more often

Quentin André@andre_quentin

Some unsolicited advice after attempting to reproduce the results of 25 marketing papers from their OSF: 1. Rename your variables in Qualtrics! There's absolutely no reason why the variables in your dataset should be named Q.1 through Q.93. It is confusing and error prone.

You have a choice between two urns to draw a poker chip from, blindfolded. You call the color and if you pick that color you win $. One urn contains an equal number of red and black poker chips. The other urn has red and black poker chips but the proportion is unknown to you.

My bluesky experience so far has been…amazing. The default feed is serving up a mix of “Elon is trash” discourse, pictures of bodega cats, furry art, and @blainecapatch. No blue checks, no ads (so far), and all around good vibes. But it needs more marketing academics…
