Test 1: mathematician - go!
Test 2: biologist - go!
Whatever it was that popped in your head with mathematician, shame on you for falling into stereotypes that way - thinking it's true that you can tell the extroverted mathematician from the introverted one because the extroverted one is staring at someone else's shoes. You're a real asshole if you just laughed at that.
No matter what else one thinks about mathematicians and their social skills, the theme linking us all together is "smart". This is occasionally true. Mostly, we're just very, very patient. Some problems remain unsolved for hundreds of years, with lots of "smart" people trying to figure them out. Anyway, the visual I get in my head is how separated from our science brothers and sisters we are. They get to do the fun exciting things like showing off their barking dog voodoo. And they won't share their toys, like the Large Hardon Collider. They even hide it underground since they know we're only good at finding where things cross the horizontal. We're congenial people*; unlike scientists, mathematicians never resort to "going negative".
Almost as exciting as watching me find the equilibrium point in some predator-prey model, right? *givesyouthehairyeyeball*
No, it's true. They get to do some wicked cool shit that looks a lot like magic.
That's not why I'm envious though.
While my mathematical brothers and sisters are in someone's mom's basement with a pencil, notepad and an imac, the scientists are upstairs at the dinner party dealing with the party crashers. They get all the fucking crazies. Anti-vaxxers, creationists, homeopathy quacks, chiropractor shit, acupuncture, water diviners, Deepockets Chopra, quantum woo and all that fun stuff.
Sure, occasionally a state legislature in the US will try to pass a law defining such that pi = 3. But really? Who's going to get excited about a rounding error - could happen to any old run of the mill crazy. Nothing to write home about. This is about the extent of abuse I get.
I just want my own share of the crazy, scientists.
