One of the giants of social psychology was a serial sexual harasser.
This new report reveals how Miles Hewstone touched, bullied, and sexual harassed numerous women during his 18 years at the University of Oxford. It's amazing how often bullying and sexual harassment go together in academia.

Yesterday we were delighted to welcome @adrienfillon.bsky.social for two sharp and thought-provoking talks on scientific publishing practices and the limits of meta-analyses.
Thank you for inspiring us to pursue science that is more open and built on integrity.

Interesting read, but worth considering (as the article does) the selection bias introduced by a) who is willing to initiate an adversarial collaboration and b) who manages to compete and publish it.

In our next episode of Nullius In Verba we will dive into the history of metascience. The first mention of 'metascience' in the literature we could find is Morris, 1938. Do you know of an earlier mention of the term 'metascience'?

Will this study about ketamine's effect on neuroplasticity ever see the light (publication)? It doesn't seem that ketamine changed synaptic plasticity after 2 weeks and 4 infusions.

Ketamine/esketamine have been claimed to work by enhancing neuroplasticity (quote from a KOL: "call them neuroplatogenes").
In this study synaptic plasticity was directly assessed but there seemed to be a near-zero effect.
Results only posted on NCT in 2023. No journal publication yet, AFAIK.

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following.
It still became a polarization machine.
Then we tried six interventions to fix social media.
The results were… not what we expected.

Can We Fix Social Media? Testing Prosocial Interventions using Generative Social Simulation
Social media platforms have been widely linked to societal harms, including rising polarization and the erosion of constructive debate. Can these problems be mitigated through prosocial interventions?...
