We are happy to release the first results of a RCT of a US program that provided $1,000/month unconditionally for 3 years to 1,000 individuals in the treatment group, with a group of 2,000 people receiving $50/month serving as the control.

These are sizable transfers. 1/ 🧵

As a plumber, I can tell you the Front populaire's platform will be worse than the RN's on the front of bathroom repairs. I know the RN wants to deport immigrants, harm homosexuals and let the police kill whoever they fancy, but hey, I'm only a plumber, just stayin in my lane.

With the Digital Markets Act, regulators in Europe are going after big platforms for self-preferencing. The Act forbids "gatekeeper" platforms from ranking their own products more favorably. Is regulation affecting Amazon's behavior? 1/n

@IglesiasYosha yep of course this is not about denying this phenomenon which is probably true in the US and some others countries (even France?), but I think (and hope) that it's not a global and independent of the various socio-political contexts worldwide...like suggested by the FT picture

Seeing this tweet promoted by Elon Musk made me want to do the stats for France.

Top 5 men: 2812, 2720, 2673, 2637, 2610
Top 5 women: 2588, 2476, 2413, 2367, 2333

Definite proof that men have a (biological?) advantage at chess and especially in top-level competition?

Wait...
