    The Wikipedia page on ant mimicry is full of fun facts, but the relevant bits:

    Jumping spiders in the genus Myrmarachne are Batesian mimics

    Batesian mimics lack strong defences of their own, and make use of their resemblance to a well-defended model, in this case ants, to avoid being attacked by their predators.

    Studies on this genus have revealed that the major selection force is the avoidance of ants by predators such as spider wasps and other larger jumping spiders.

    But also (not specific to Myrmarachne):

    Ant mimics can be myrmecophilous, with the mimics and their ant models living commensally together. In the case of ants, the mimic is an inquiline in the ants’ nest. Such mimics may in addition be Batesian or aggressive (predator) mimics. To overcome ants’ powerful defences, mimics may imitate ants chemically with ant-like pheromones, visually, or by imitating an ant’s surface microstructure to defeat the ants’ tactile inspections.

    The US effectively does both: the lotteries are run by the states and total prizes are much less than total ticket sales, generating net revenue for the state. Winnings are taxed like other income, meaning there are federal taxes and in many states state taxes.




  • There’s great arguments here about how a service corps could bridge divides and give all youth a better pathway from highschool into the (often predatory) worlds of job markets and higher ed, and also great arguments about why mandatory service infringes on freedom pretty significantly.

    Is there a way to structure a national year of service idea that gives people the freedom to opt out yet would still get chosen by many kids from diverse backgrounds? Like how do we get kids who have had a college fund ready to go since they were born to see the benefits of spending a year building bridges? It would be a neat cultural shift.
