  • It’s percentage of the entire population, if you organized everyone from lowest to highest IQ, what percentage of the entire population would you need to include for them to be in the top. It’s a little clearer when a point of interest is near the top. E.G. “person is in the top 1% of people in terms of wealth.”

    A less kind way to say it is ‘91% of people have a higher IQ than this person’.


  • I imagine if my occupation includes carrying a gun, interacting with citizens, and a historically high rate of extrajudicial deaths amongst people I am supposed to be protecting. A publicly accessible camera would be beneficial to easing the minds of those I interact with and providing evidence for any actual instances where I felt my life was threatened.








  • Linnaean taxonomy classifies apes and monkeys as two closely related groups. This is the classification system most people are taught in grade school.

    Cladistics is a style of classification that seeks to organize species and groups of species from when they branched off of other groups of species. In this style, everything is defined by novel features, but they are still members of the more ancient clade. Birds for instance, would be a novel clade emerging from Dinosaurs, and thus all birds are also dinosaurs, but not all dinosaurs are birds.

    Because there are two groups of monkeys with unique characteristics (new world and old world), and apes have unique adaptations not found in either group, we have no way of cladistically defining a monkey in a way that meaningfully does not also include apes.

    As a side note, this is where the phrase “there is no such thing as a fish” comes from. ‘Fish’ in the Linnaean sense are a huge and diverse category. Two random members of the fish class would likely be far, far more distantly related than a random mammal and a random reptile.





  • The blue and yellow maps are flipped because they are on opposite sides.

    The green parts are where opposite sides line up (through the center).

    The “two” Antarcticas aren’t on opposite sides of the same globe, the Antarctica (blue) lines up with the opposite (yellow) northern Greenland (overlap in green). Just like the blue Greenland mainly overlaps the yellow Antarctica showing green.

    Just find a spot on the blue map, and then look at the yellow map to see what’s on the opposite side (it looks reversed since you are seeing that other map from below.)

    Even without going full ‘free housing for everyone’ utopia, it would be nice if the rent students currently pay to landlords was recoverable when the space is no longer needed. The same way people paying mortgages can just sell their house even before it is fully paid off. We wouldn’t need to drastically reshape society in order to allow people to invest in their own futures rather than shovelling most of what they have into a landlord’s pocket.
