Thank you for sharing. Beautiful

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

My theory is that the cats understand the technology and are trying to export it to humans.

I didn't know, but HAPPY Birthday!

You best get out of my way in the gym when you see me dosing 200mg of ✨sparkling peach✨ caffeine

Oh wow I didn't know that. Thanks for educating!

Summary of design and results from our three studies. (A: Design) Each study used a similar experimental design, measuring both positive and negative demand in an online experiment, with three commonly-used task types (dictator game, vignette, intervention). Our experiments had ns ≈ 250 per cell. (B: Results) Observed demand effects were statistically indistinguishable from zero. The plot shows means and 95% confidence intervals for standardized mean differences derived from frequentist analyses of each experiment and an inverse variance-weighted fixed-effect estimator pooling all experiments (solid bars). Prior measurements of experimenter demand from a previous dictator game experiment (de Quidt et al., 2018; standardized mean difference from regression coefficient) and a meta-analysis primarily including small-sample, in-person studies (Coles et al., 2025; Hedge’s g statistic) are also shown for comparison (striped bars). The main text includes Bayesian analyses that quantify our uncertainty.

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

We've updated a paper on the 3-year, $1000/month U.S. guaranteed income study.

New results, in 3 figures: 🧵

1) Subjective well-being significantly improved in the treatment group in year 1, but there were no significant differences between the treatment & control group after that. 1/

This evergreen post is my go to.

Anything that makes future Associate Professor Erin Westgate happy has my vote 😁

Why do societies reliably develop strikingly similar traditions like dance songs, hero stories, shamanism & justice institutions?

In a new BBS target article, I propose a theory for such "super-attractors" + cultural evolution more broadly. Now open for commentary: www.cambridge.org/core/journal...

Thanks!

I unfortunately think demand characteristics are an underappreciated cause of a lot of effects in the lit

This is in my view the most relevant paper about demand effects, and one of the most important papers to read for anyone doing social science research!

I highly recommend it!

Demand characteristics are a fundamental methodological concern in research with humans

Yet little is known about the magnitude and consistency of these effects

In a new paper, I, M. Wyatt, and @mcxfrank.bsky.social take stock of what we’ve learned via meta-analysis

Neat!! I'll be following this development with great intrigue and enthusiasm!

Thanks, Daniel!

The first version of the open science blog archive is complete, with 3530 posts from 52 blogs. Browse them in the online Shiny app: shiny.ieis.tue.nl/open_science... All blog posts are ordered chronologically. Have fun exploring part of the open science history in psychology!

If you're interested in watching me gibber about papercheck for an hour, I'm giving a local seminar tomorrow at 15:00 UK time. DM me before 14:30 and I'll send you the Zoom link.

Still playing around with creating an archive of open science blogs discussing the replication crisis. Here's an overview of when blogs first posted, and last posted. 2016 and 2017 were a peak for psychologists interacting and communicating through in total more than 3000 blog posts.
