make eugenics great again?!

A most interesting (and ghastly) article in The Guardian by Portland writer Derek Beres on “Maga’s era of ‘soft eugenics’: let the weak get sick, help the clever breed“. It points out how significantly the Trump administration is influenced by (soft and not that soft) eugenics ideas. Starting with (the US Secretary of Health) Robert F Kennedy Jr’s MAHA (“make America healthy again”) movement that centres on “natural” selection of the fittest and healthiest members of the community, from his anti-vax positions to his insistence on health being a personal responsibility, to his denying the genetic roots of autism (or letting those impacted disappear from the gene pool), and to stopping NIH funding of research on HIV, vaccine hesitancy,  vaccination rate disparities, and COVID-19, all pointers to this selection by (at best) passivity from the State.

Similarly, Elon Musk’s and Trump’s fascination with IQ tests and levels need not much arguing towards eugenism when recalling that IQ was intrinsically linked with eugenism (as for instance setting the IQ bar in many US States forced sterilisation programs that ran till the 1980’s). Same for the current natalist discourse that mimics the one of the earliest eugenists like Galton, Pearson and Fisher. Trump’s proposal of a baby bonus echoes 1930’s Fisher’s call for an allowance so “that the standard of living of the competent will rise, and that of the incompetent will fall”. And the defunding of USAid, Head Start, HHS and other programs that contribute to children health, nationally or internationally, follows the same furrow that the resulting (numerous) deaths and diseases will only impact the “unfit” part of their Brave New World.

A number of entries of interest [to me] in that Nature issue: from the Capuchin monkeys that break stones in a way that resembles early hominins biface tools, to the persistent association between some sounds and some meanings across numerous languages, to the use of infected mosquitoes in South America to fight Zika, to the call for more maths in psychiatry by the NIMH director, where since prevision is mentioned I presumed stats is included, to the potentially earthshaking green power revolution in Africa, to the reconstruction of the first HIV strains in North America, along with the deconstruction of the “Patient 0” myth, helped by Bayesian phylogenetic analyses, to a cover of the Open Syllabus Project, with Monte Carlo Statistical Methods arriving first [in the Monte Carlo list]….

“Observations should not converge on one model but aim to find anomalies that carry clues about the nature of dark matter, dark energy or initial conditions of the Universe. Further observations should be motivated by testing unconventional interpretations of those anomalies (such as exotic forms of dark matter or modified theories of gravity). Vast data sets may contain evidence for unusual behaviour that was unanticipated when the projects were conceived.” Avi Loeb

One editorial particularly drew my attention, Good data are not enough, by the astronomer Avi Loeb. as illustrated  by the quote above, Loeb objects to data being interpreted and even to data being collected towards the assessment of the standard model. While I agree that this model contains a lot of fudge factors like dark matter and dark energy, which apparently constitutes most of the available matter, the discussion is quite curious, in that interpreting data according to alternative theories sounds impossible and certainly beyond the reach of most PhD students [as Loeb criticises the analysis of some data in a recent thesis he evaluated].

“modern cosmology is augmented by unsubstantiated, mathematically sophisticated ideas — of the multiverse, anthropic reasoning and string theory.

The author argues to always allow for alternative interpretations of the data, which sounds fine at a primary level but again calls for the conception of such alternative models. When discrepancies are found between the standard model and the data, they can be due to errors in the measurement itself, in the measurement model, or in the theoretical model. However, they may be impossible to analyse outside the model, in the neutral way called and wished by Loeb. Designing neutral experiments sounds even less meaningful. Which is why I am fairly taken aback by the call to “a research frontier [that] should maintain at least two ways of interpreting data so that new experiments will aim to select the correct one”! Why two and not more?! And which ones?! I am not aware of fully developed alternative theories and cannot see how experiments designed under one model could produce indications about a new and incomplete model.

“Such simple, off-the-shelf remedies could help us to avoid the scientific fate of the otherwise admirable Mayan civilization.”

Hence I am bemused by the whole exercise, which deepest arguments seem to be a paper written by the author last year and an interdisciplinary centre on black holes also launched recently by the same author.
