I don't post everything I write on BlueSky, but I think this piece may resonate with a few of you. It is for those interested in the backstory of the debate, why it matters, and whether it is even a scientific question to ask whether people are rational.

Rational Choice Theory has been a short-cut to nowhere for the field. We need to re-think the ‘drosophila of decision science’ jtpeterson.substack.com/p/the-drosop...

Got a nice honorable mention from Experimental History🐐

New article on context and the psychological paradigm, arguing that the boundaries we have put around "psychology" are in the wrong place. What we have dismissed as context is actually content. jtpeterson.substack.com/p/rethinking...

The behaviors, problems, and outcomes that impact your customers most usually don't happen inside your product. Listen to @jaredpeterson.bsky.social describe how #UX and #prodmgmt often neglect what happens outside the product. www.productcoalition.com/p/behavioura...

To those interested in the science of decision-making, here is a primer on the main schools of thought, the personalities behind them, and some resources for learning more. substack.com/home/post/p-...

Has anyone done a comprehensive analysis of factors that people think are, or think should be, ethically relevant when doing triage? eg likelihood of survival is relevant, some think "woman and children first", most think race is irrelevant, etc.

These price comparisons are getting out of control

Cognitive Turn people. Are any of you reading about Naturalistic Decision Making? Started reading *A Cognitive Theory of Reasoning and Choice* and thought, "this is just a math-y version of Dataframe Theory of Sensemaking, and Recognition Primed Decision-Making.

Newly published follow-up article to the #BehavioralScience framework tier list series I've been doing the past few months. Curious to hear your thoughts! open.substack.com/pub/jtpeters...

Cool to see lots of ppl getting excited about “Science Goodreads”! (x.com/sanjehorah/s...) Why it doesn’t exist yet is an interesting rabbit hole I went down a few years ago (which also resulted in me joining the @asterainstitute.bsky.social Open Science fellowship) >

Kahneman would resist so long as he can't see it because wysiati Thaler would resist so long as it is stored with the cashews Zimbardo would write up how he resisted, but it would be fake Freud would be torn, but Id would win Mischel would pretend it was a picture of a ring, but would give in

Only someone as uninterested in the ring as Bombadil could resist the One Ring and throw it in Mount Doom. But such a person would never care enough to try. Basically, no one with main character energy could ever fulfill the quest. Which is why it falls to the unlikeliest of creatures; hobbits 1/

In economics, editors, referees, and authors often behave as if a published paper should reflect some kind of authoritative consensus. As a result, valuable debate happens in secret, and the resulting paper is an opaque compromise with anonymous co-authors called referees. 1/

We did interviews with multiple people who refused to turn their camera on, responded with a delay, and even asked us to put the questions in the chat. Super obvious they were using an LLM. But it shocked us. They thought they could get away with pretending to be a medic during a live interview!

Over the past couple months I have been doing a tier list of #BehavioralScience frameworks. It generated lots of really great discussion with many disagreements. Here is an updated and centralized resource for all the rankings. substack.com/home/post/p-...

This is a really useful heuristic that I also use. For many academics, everything is a nail to be hit by their particular hammer. And if you criticize the hammer, the same defensive mechanisms are always present

Does anyone have suggestions for feeds to follow that haven't been overtaken by politics? I came here to discuss research and philosophy, not for political platitudes and rage posting

I just got the kids down for naptime so I wanted to take a second to point out two key problems (and a few areas of agreement) I see with this morning’s @emmagoldberg.bsky.social @nytimes.com article about effective altruism: 🧵 bsky.app/profile/nyt...

This is a hard question because the way we (I?) think about BehEcon has changed so much System 1/2 don't exist, but it's a useful distinction. Biases aren't as systematic as we thought, and don't imply irrationality, but nevertheless represent true deviations from economic models 1/

Three formal arguments for why there cannot be a finite set of cognitive biases. The lack of a finite set of biases is one reason I believe Heuristics and Biases cannot survive long term as a prescriptive paradigm. A paradigm of deviations must eventually collapse under its own weight.

Read that new Gigerenzer paper and really enjoyed it. Mostly agree with everything. The Cold War context was interesting and new to me. But at some point it would be really nice if someone actually surveyed HB and FF researchers about what they actually believe

Very curious how others feel about the idea that trailing elipses are a dark pattern.

What percentage of published social psychology research do you believe reflects a true and justified insight? By 'true,' I mean findings that accurately capture some aspect of human nature. By 'justified,' I mean studies that are well-designed and methodologically sound. (Ignore Gettier)

New article on the misleading labels of Behavioral Science. In it I critique five labels that made the field popular; nudge, behavior change, empirically tested solutions, bias, irrationality. All misleading or narrowing in their own way www.nuancebehavior.com/work/the-mis...

It's taken many years, but chemistry is finally beginning to catch up with cutting-edge advances from psychological science.

This is a good schelling point to rally around. And I'll add "reshare 1 thing" to the list

List of Psychology Starter Packs on FB. Feel free to share with your FB friends, and yell if you want me to add your pack to the list. www.facebook.com/share/p/15JC...

Fun visual illusion! The rectangle on the left is bigger, but years of seeing this kind of stuff has broken vision scientists' brains into saying they are actually the same.

The extension is called DeArrow (dearrow.ajay.app). If this spreads as a concept, a company will eventually implement it with first party support in the platform, and the users will love it & other companies will be forced to compete and copy them. cc @nathanpmyoung.com

Three features I'd like 1. Find starter packs populated with people I already follow to find more like them 2. Find out which starter packs the people I follow have followed 3. Know which starter packs I'm in @bsky.app any plans for this?

Different disciplines argument for P Historians: here are a bunch of historical facts, some of which relate to P Philosophers: here is a carefully crafted, deductively valid argument for P with only one wildly false premise

Kahneman: One of my least favorite words is the word irrationality. I've never used it. I view irrationality as a technical definition... Spencer: Is [it a] mischaracterization that...your work shows that humans are irrational? Kahneman: Oh, absolutely. clearerthinkingpodcast.com/episode/072

Didn't realize there was a central location for finding starter packs. Super useful blueskydirectory.com/starter-pack...

#introduction I'm an applied researcher interested in - expert and rational decision making - motivation and behavior change - sensemaking and relevance realization - philosophy of science and how context breaks our models - AI - What all this implies for science and industry (1/5)

More accurate headline: "After decades of advocating for the view implicit in his premises, neuroscientist never once questioned the assumptions he started with" I'm a determinist too. But framing this as something neuroscience provides evidence for is just bizarre and wrong.

"Your users are overwhelmed by the number of options that your app provides. Your only solution as a product manager; reducing options. Or at least, that is the story you are being told. But is that right? Not quite." New article up on Nuance! www.nuancebehavior.com/work/choice-...
