Happy gotcha-day to our precious princess Mellori!

11 years of unmatched chaotic energy, yet the gentlest soul when it comes to people. These days, toys are safe. Not food though, nor lip balm or chewing gum or hand cream -- will. eat. everything.

Experimentology cover: title and curves for distributions.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

We provide the first evidence from a randomized double-blind placebo control study of oral contraceptives on women's preferences for masculine and symmetric faces in men. We find no evidence of an effect. Similar, our correlational results testing for an association between menstrual cycle phases and facial preferences fail to reject the null hypothesis of no association, as do our estimated correlations between hormone levels and facial preferences. Although the early literature largely found support for variation in facial preferences over the menstrual cycle and with oral contraceptive use (Feinberg et al., 2008; Johnston et al., 2001; Little et al., 2002; Little et al., 2013; Penton-Voak et al., 1999; Roney & Simmons, 2008), our null results align with more recent large-sample correlational studies (Jones et al., 2018; Marcinkowska et al., 2019). One possible motivation of the hypothesis that oral contraceptives lower the preferences for facial masculinity and symmetry is in terms of the dual mating theory. In a recent review of the literature Jones et al. (2019) point out several methodological problems in the early work testing this hypothesis, such as low statistical power, and conclude that recent and methodologically stronger work fails to support the hypothesis. Our findings lend further support for their conclusions.
There are also several reasons for why false positive results could have been published in the earlier literature. Low statistical power increases the probability for false positive results as well as inflated effect sizes. Many of the older studies also rely on self-reported menstrual cycle data, which is subject to mismeasurement. In addition, without pre-analysis plans there is room for the so-called β€œresearcher degrees of freedom” (Simmons et al., 2011) to influence the analysis such that statistically significant results become more likely to be false positive ones. This can occur through excluding observations, using covariates, testing…

New results from one of the few preregistered, placebo-controlled combined oral contraceptive RCTs. No pill effects found on preferences for masculine or symmetric faces, no menstrual cycle effects.

You can date a display of Australian mammals by whether the distribution maps recognise recent extinctions. Eastern #quolls went extinct in mainland Australia in the 1960s, but they're still on this historic display at @hunterianglasgow.bsky.social Zoology Museum.

What is common in your field but shocks outsiders?

Translation is about 80% skill in your native language, 20% skill in your second language.

It's not about knowing what is being said. Anyone can do that. It's about saying the same thing in a different language with the same emotional impact.

This is a really important new study (still preprint) indicating that these materials increase liklihood of self-diagnosis but *don't* increase symptom reporting, suggesting the materials change not symptoms but the framing of them
