OK, het klopt niet helemaal, sommige proffen zijn natuurlijk sadisten, maar dat zijn uitzonderingen. Het punt is dat, zoals Marchant uitlegt, de "buisvakken" (statistiek, economie, bij de ingenieurs thermodynamica 😉) inderdaad gewoon intrinsiek moeilijk zijn, en dat je /
quasi onmogelijk door een paar marathonzittingen juist voor de examens een maandenlange verwaarlozing van het vak kan rechtzetten, tenzij je dus zéér inteliggent bent. En zoals Marchant ook terecht aanhaalt, je kan niet onder een bepaald niveau zwakken zonder dat je vak /

The generals and admirals who planned the invasion of Japan had no idea of the Manhattan project, so the assumptions they used in their planning give an interesting insight in the scale of the massacre that would have taken place without the nuclear bombs. /
Extrapolating from Iwo Jima and Okinawa, it was expected that US casualties would range in the hundreds of thousands (with up to two millions in the most pessimistic scenarios) - at least a doubling of the US body count until then. /
But just as interesting is the impact a continuing of the war would have had on the Japanese population. The US has more or less completely destroyed the Japanese merchant fleet, and Japan was on the brink of a mass starvation that was unseen in history. /

In "Nudge", @R_Thaler and @CassSunstein often argue that neoclassical economics assumes that humans behave as if they're Mr Spock, while, in reality, we behave more like Homer Simpson. There's an implicit assumption in this analogy that Mr Spock is the normative reference/
point : deviations from the Spock standards are suboptimal, and what they call "libertarian paternalism" should nudge people towards the choices they would make if only they were more like Spock. But @juliagalef beautifully illustrates why Spockism is not the right standard for /
rationality when you're not facing fellow Spockians. There are beautiful examples of this in experimental game theory. Consider the game where you have to state a number, and the winner is the person whose number is closest to half of the average guess. How would you play? /

Hidden within the @ITF_Forum report on #micromobility "30 km/h is the maximum limit recommended for cars in city streets to reduce the risk of death or serious injury from a collision of cars with pedestrians and other vulnerable road users."

itf-oecd.org/sites/default/…
On the topic of shared micromobility itself: "Shared micromobility predominantly replaces walking, cycling and public transport trips yet could also substitute short car trips. The broadest benefit ...could be increasing
the catchment area of public transport. " /
"Their widespread availability, particularly for first/last-mile connections, could improve access while shortening commuting time and reducing reliance on cars. However, micromobility ... raise concerns of nuisance on sidewalks, the safety of users and pedestrians" /

The best point yet I read in @HansRosling 's "Factfulness": in the past, people did not live in balance with nature. They *died* in balance with nature. As Hobbes already knew, live was short, nasty and cruel. /
I quite often say that books are highly recommended, but "Factfulness" is a must read in the most literal sense of the word: it should be put on the school curriculum. Not just because it sets so many things straight about the world, but because it is one big argument in /
favour of a data rather than impressions based approach to understanding the world. If the data tell you that your priors are demonstrably false, you need to update your priors. Also, it is a good guide to the mental biases that guide our /
