Thanks to @alexaroblesgil.bsky.social for this beautiful coverage of our new paper in @nytimes.com !
Having an imaginary friend, playing house or daydreaming about the future were long considered uniquely human abilities. Now, scientists have conducted the first study indicating that apes have the ability to play pretend as well.
At a Bonobo’s ‘Tea Party,’ Scientists Find Hints of Imagination
In a playtime experiment, researchers found that our closest living relatives have the capacity for make-believe, too.

Which reminded me that we can and should have public gyms and pools, except we don't because that would help people and families have public access to nice things, which is not a thing the U.S. is known for.

Trump has served a default on the folks running the public project so he can take the course and turn the national park courses into, it seems obvious, a high end private course administered by his own golf company
