Bit of a random blog post, but sometimes my weird little hobbies and work coincide: How to build a watch to celebrate an academic milestone! www.dalmaijer.org/2026/10/maki...
This is a photo of a watch in a presentation box. The box is of a brown wood, with a glass top, and a velvety brown interior. The watch inside is on a black strap; the case is polished stainless steel, 33 mm in diameter, and fitted with a  curved crystal and a modest crown. The dial shows the red logo of the University of Bristol above the hands, the text “PhD” in black, and red lines to mark the hours. The hour and minute hands are steel-coloured with rounded tips and bars of lume, and the second hand is black with a curved end.

A theorem you'll never forget: Napoleon's theorem. Take any triangle. Erect equilateral triangles on its three sides. The centers of these triangles are the vertices of another equilateral triangle!
Napoleon's Theorem

Given any triangle, construct an equilateral triangle on each of its legs.  Then the centers of the three outer triangles form another equilateral triangle (Napoleon triangle).

Picture of this situation.

A reminder that the original Stanford prison experiment, as well as being wildly unethical, was ridiculously bogus, guards actually being coached to be abusive to prisoners and the supposed experimenter (Zimbardo) acting as prison superintendent. theconversation.com/the-infamous...
theconversation.com
The infamous Stanford prison experiment was flawed – so why is it still so influential today?
A French science historian dug deep into the true story of the Stanford prison experiment – revealing ‘guards’ were actually coached to be brutal. His findings are now available in English.

New review of methods to address demand characteristics by @ocorneille.bsky.social, Chloé Bernard, and @peterlush.bsky.social doi.org/10.3758/s134...
Demand artifacts stem from participants’ beliefs about treatment effects and motivations to respond in accordance with these beliefs. These artifacts typically build on subtle cues that exert extraneous influences unbeknownst to researchers, through processes that are not part of their stated theory. Demand artifacts threaten the internal and external validity of studies, and they have been supported across a wide range of psychological domains (e.g., clinical, cognitive, and social psychology, psychology of perception) and beyond (e.g., consumer research, experimental economics, psychosomatic medicine, neurosciences). This article reviews prominent methods used to address them. Our discussion is structured around Corneille and Lush's (2023) framework of demand effects, which distinguishes between participants’ hypothesis formation, motivation, and implementation strategies. We conclude this review by discussing three fundamental questions of broad interest: when should we care about demand artifacts, what is the best approach for addressing them, and how can we usefully build on demand artifacts?
