data science in La X

As the [catholic] daily La X has a special “Sciences&éthique” report on data science and scientists, my mom [a long time subscriber] mailed me [by post] the central pages where it appeared. The contents are not great, focusing as often on a few sentences from  and missing on the fundamental limitations of self-learning algorithms. As an aside, the leaflet contained a short interview by Jean-Stéphane Dhersin, who is head of the CNRS ModCov19 centralising platform [and anecdotally a neighbour] on the notion that a predictive model in epidemiology can be both scientific and imprecise.

lunch with David [and Meursault]

“My real beef, my real anger, is that hugely expensive programmes like test and trace did not have built in, right from the beginning, a capacity for experimental evaluation. They should have been running studies, different methodologies, different ways of tracing. As it is, we don’t know what benefit it’s had. It’s like rolling out vaccines without ever measuring whether they have an effect or not. For Heaven’s sake!”

MASH in Le Monde

“À l’université, j’étais le matheux qui savait parler aux statisticiens.”

This weekend edition of Le Monde had [most of] Cédric Villani as its cover story. Mostly about his new career as a representative of Orsay at the French Parliament. And a member of the presidential majority. But the weekend edition being the weekend edition, it cannot escape its glossy tendencies and rather than focussing on the political agenda and achievements of the député, including a radical restructuring of the maths curriculum in French high schools, or maybe even his position on the harsh stance of the Macron government on migrants and refugees, Le Monde spends most of the article on the extra-ordinary personality of Villani.  Paris-Match-like. Which leads to quote as the one below, where I find myself at a loss on how to interpret this “ability to speak to statisticians”…!
