Mitt främsta önskemål, om vi ska ha en debatt om gener och heritabilitet nu, är att vi använder de svenska termerna "anlag" och "arvbarhet" istället.

![To begin, distributions are never normal. For some this seems obvious, hardly worth mentioning, but an aphorism given by Cram´er (1946) and attributed to the mathematician Poincar´e remains relevant: “Everyone believes in the [normal] law of errors, the experimenters because they think it is a mathematical theorem, the mathematicians because they think it is an experimental fact.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:kwjddjickma3syepdsfufyvi/bafkreifw25h2nnb3ylgdumcsctlyh6wdbxam7ajlnbwnca7hdxef5q6bo4)
![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.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:v6qwaqo24zfrq5fj7ceibxqk/bafkreigaspshdrleahxzyp6b6rjodus6gk4zcoaw77smu7olklmbshdx74)
