After all these reports of authors adding language instructions for LLM reviews in their papers I wanted to check this myself and I downloaded the .tex source from one of these papers.

Here is an example.

Sounds like what often happened in my grad school meetings with my advisor.

Restricted card use within a single brand can greatly reduce profitability for issuers. Notably, restricted use persists even if issuers set very competitive rewards outside their co-branded cards' featured brands. We discuss managerial implications for credit card co-branding partnerships. 🧵5/5

Second, even if one knows that their Best Buy Visa offers the best reward on something outside Best Buy (e.g., 3% back on gas, for real!), the Best Buy brand on the card makes off-brand purchases feel like a bad “fit” with the card. 🧵4/5

First, people may think, for example, “Best Buy Visa’s rewards are obviously for Best Buy,” and so they pay less attention to its actual reward terms because they think they already know what the rewards are about. 🧵3/5

Co-branded credit cards can be used everywhere and usually offer competitive rewards outside their featured brands. However, we find that people are reluctant to use them more widely.

Why? We identify two psychological mechanisms. 🧵2/5

✨New Working Paper!!✨ (w/ Cindy Cryder and @scottianrick.bsky.social)

Using real credit card transactions and scenario experiments, we find people restrict their use of co-branded credit cards within featured brands, hurting both cardholders and card issuers. 🧵1/5

I check out when I want a receipt from smaller indie hotels. Sometimes they don't respond to email requests.

Really proud of this new work out @psychscience.bsky.social. Led by the amazing but bluesky-less Amanda Geiser and with @deborahsmall.bsky.social.

We show that when comparing moral wrongs, people are (much) more willing to “scale up” than to “scale down” condemnation and punishment…

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork}

How odd is a cluster of plane crashes? In the space of eight days, three passenger planes have been lost in mid-flight - how unusual is a cluster of this kind?

In light of the latest plane crash news, this seems relevant again.

A good general epistemic rule of thumb: If you have spent a few hours or weeks studying an area large numbers of smart, educated people have worked in for decades, and you believe you have discoverer an earthshattering truth they all missed, your default should be to regard this as VERY unlikely.

Kindleberger Spiral is an inward spiral, visualizing the steady collapse of world trade.

Kindleberger Spiral is an inward spiral, visualizing the steady collapse of world trade.

As someone trained as a trade economist, it is my duty to share the 1929-1933 Kindleberger Spiral, showing the month-month decline in global trade due to the combined factors of the (global) Great Depression and retaliatory tariffs. Smooth Hawley is implemented mid-June 1930.

One of the best things you can do right now is read books. Buy them. Borrow them from the library. Gift them.

Read history. Read fiction. Read science writing. Read anything that shows you the world is bigger than what fascists say it is.

Read to remember why your resistance matters. 📚💙

Participating in a behavioral experiment with Gemini Live
Participating in a behavioral experiment with Gemini Live YouTube video by Tobias Werner

Just used Gemini Live to participate in a beh. experiment without even reading the instructions or speaking the language.

LLMs acting as participants on platforms like Prolific could pollute data meant to study humans. With OpenAI’s operator model, this issue is growing.

All NIH study sections canceled indefinitely. This will halt science and devastate research budgets in universities.

Little research has directly examined whether prediction and likelihood judgment actually correspond, probably because such connection usually feels intuitive. Our findings call for research attention on this front. 11/n
