Ignoring the Science: The Curious Case of Cell Phone Bans

In my essay today for @RCInvestigates I look at the burgeoning #digitalabstinencemovement, including #socialmedia bans, #cellphone bans and the claims that Edtech "ate" kids' education.
None of these policies or claims are well-based in actual data.

ABSTRACT
The extended evolutionary synthesis (EES) is a school of thought that maintains that genetic determination and natural selection are over-emphasized in the study of evolution at the expense of non-genetic inheritance and processes of evolution beyond selection. Its proponents call for the de-emphasis of genetics and the adoption of a broader model of inheritance that includes cultural and epigenetic transgenerational effects and strong adaptive phenotypic plasticity. Presenting itself as a radical alternative to what it claims is a rigid and ossified theoretical orthodoxy, the EES has lately gained considerable traction among scholars of human evolution, and a distinct sub-branch of the EES unique to the biological anthropological study of human evolution has emerged (the EES in human evolution). To date, however, no direct comparison between the EES in human evolution and other contemporary evolutionary approaches has been attempted to evaluate whether the EES in human evolution affords researchers an edge in articulating good questions and structuring research programs to answer them. After reviewing the landscape of evolutionary theory, we evaluate whether the EES in human evolution is capable of delivering the processually pluralistic vision of evolution it has long promised and whether it brings something that the decades-long ongoing synthesis (OS) of evolutionary theory since the modern synthesis does not. We then conduct a head-to-head comparison to evaluate the relative explanatory efficacy of the EES and our preferred OS theoretical framework on several issues of human morphological evolution. We demonstrate that evolutionary perspectives as drawn from the OS have a much more clarifying effect on the investigation of human evolution than their EES-based competitor. Far from being a radical extension of evolutionary thought, the EES in human evolution offers little more than another idiom in which to tell adaptationist stories and triumphalist narrβ¦
A much-needed critique of the Extended Evolutionary Synthesis (EES) as applied to human evolution, by @evoroseman.bsky.social and Ben Auerbach (2026).

Hadza food-sharing is egalitarian, yet offers in giving games have never matched the equitable redistribution seen in real life.
In this study, we allowed people to give *or* take. Lifelike equitable distributions only appeared when people took from peers in surplus.

A very important study. Many figured that chimp warfare was adaptive. Now we have proof. Lethal displacement of a neighbor doubled fertility and even had a greater impact on survivorship. However, as usual we need more details as other questions emerge.

People don't like individuals who vigilantly monitor and reprimand wrongdoings at work.
These "hall monitors" are seen as less moral and hyper competitive (the only people who like them are other vigilantes).

Do you really think it is implausible to suggest that human males have evolved to be attracted to secondary sexual characteristics in females? (And yes, birds liking clouds is a dumb comparison.)

Why would clouds make birds happy? (Happy enough to evolve wings?) Your theory makes no sense.
You seem to think that it is easy to come up with adaptationist hypotheses ('just so stories'), but you haven't managed to come up with one that even gets off the starting blocks.

Above all you would need to propose a theory of why being close to clouds was an adaptive benefit, ie why natural selection would have favoured it. (And, you can never control for 'all' other variables ever; so which other control variables did you have in mind?)

Why would birds find clouds attractive?! In any case, you could test whether they do. In fact, the theory makes lots of testable predictions. Flight evolved in cloudy places. Less flying in clear skies⦠etc

Ok, so you think that the human body and brain contains adaptations (such as the visual system), but you draw the line for some reason at sexual psychology. Do you think mate preferences evolved in other animals? Why not in humans?
