My book, Taming the Careerists, will be published by Cambridge University Press this September! There is growing debate over whether federal employees should be easier to dismiss in order to make them more responsive to presidential directives. What would be the consequences of such a change?

the new paper on bouba/kiki in chicks is utterly compelling canonical, elegant method from comparative cogsci & its partner in developmental science, ultra-simple design, ultra-clear effects, no need for fancy analyses, machine learning, or AI it appeared in an appropriately badass venue (Science)

Matching sounds to shapes: Evidence of the bouba-kiki effect in naïve baby chicks Maria Loconsole1*, Silvia Benavides-Varela2,3, Lucia Regolin1 Humans across multiple languages spontaneously associate the nonwords “kiki” and “bouba” with spiky and round shapes, respectively, a phenomenon named the bouba-kiki effect. To explore the origin of this association, and whether it is unique to humans, we tested the bouba-kiki effect in baby domestic chickens (Gallus gallus). as a precocial species, chicks can be tested shortly after hatching, allowing us to control their pretest experiences. Similar to humans, both 3-day-old [experiment 1 (exp. 1)] and 1-day-old (exp. 2) chicks spontaneously choose a spiky shape when hearing the “kiki” sound and a round shape when hearing the “bouba” sound. results from naïve young animals suggest a predisposed mechanism for matching the dimensions of shape and sound, which may be widespread across species.main fig from the paper showing the association between bouba/round and kiki/spiky in newborn chicks

Automated nuclear weapons systems are not just a Hollywood plot device. In this #Firstview article, @joshschwartz.bsky.social and @mchorowitz.bsky.social evaluate how they could impact the credibility and effectiveness of nuclear threats. www.cambridge.org/core/journal...
