Because The Fonz is a fundamentally magical creature, capable of both mind control and telekinesis, Happy Days could not have “jumped the shark” as a consequence of Fonzie literally jumping over a shark on water skis. In this essay I will

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: https://t.co/p2Tl6gkO7z

🚨 My New Research in @JofMarketing!

What makes some #influencers’ posts more impactful?
-High arousal language boosts engagement with micro influencers -but it backfires for macro unless they post with an informative goal or highlight product limitation

@HernanBruno1975 Not at the moment… :(

I’ve been over at 🟦 for the past two weeks and I love it. Will probably be posting exclusively over there, not that my posts are anything to look forward to ⤵️

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.

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…

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: https://t.co/0pK7EYpk8e

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.

@JZBerman Did I type which? Can’t see how autocorrect could turn wish into which. Anyway I meant wish.

@JZBerman Which I could vote for both!

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.

@HernanBruno1975 This is unfair to the Globetrotters, who can actually play basketball

@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…?

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.

@CFCamerer This is so good

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…
