Obviously you can't give them an IQ test but all the data I've seen (and I am no expert here) shows they are possible the smartest arthropod out there. There are of course different species of jumping spider so mileage may vary.

That’s definitely the premise Adrian Tchaikovsky’s Children of Time haha

I've watched videos of them stalking prey and they seem extremely intelligent for their size. It's very impressive.

Bees' intelligence relies on them being a hive organism.
