I've been trying to figure out what I (and so many others) dislike about AI writing. It's very clear. It's good at getting the level right, not going over the reader's head but not talking down. Often it's clever, and sometimes even funny. (At least Claude is) ...

“It is easier for a working-class kid to pick up an SAT prep book and study it intensively than it is for them to go on a community-service trip to South America, play travel lacrosse, or flatter the sensibilities of an upper-middle-class admissions official.”

Time's running out to sign up for the Economic Science Association world meeting July 15-17 in beautiful Marina Del Rey (Los Angeles). The day before (July 14), we're hosting a "choice process" symposium with many amazing speakers. Best part - it's free with ESA registration.

Autonomous AI agents are now built into many browsers. A naive user can take an online survey with as little as the click of a button. For behavioral research, which depends heavily on online samples, this is a real problem. (1/6)

At a minimum, eye tracking confirms that eyeballs are pointed at the screen, which alone keeps AI agents from completing studies on their own. With a bit more work, researchers can also verify that a human is genuinely attending to the task. (5/6)

When you collect data online, are the results from humans or AI? In a project led by Booth PhD student Grace Zhang, we estimate the prevalence of AI agents on commonly used survey platforms: osf.io/preprints/psyarxiv/xc… 🧵

Estimating the threat of AI-agent responding across online survey platforms

Recent research and advances in LLMs have led to widespread concern that AI agents could pose as human online survey-takers. However, it remains unclear how prevalent AI agents are on these platforms...

New paper in @CognitionJourn, where we show how attention impacts political choices. With an eye-tracking study, we find that people's voting choices aren't set in stone - they take longer to vote on divisive issues and can be swayed by gaze manipulations. authors.elsevier.com/sd/arti…

Building on past attentional drift diffusion model (aDDM) work, we find that gaze has a stronger effect on choice for more important issues. This work shows how ballot design can influence political outcomes, by drawing attention to certain options. Project led by @taroyang3302.
