Rafe Meager (they/them) @economeager.bsky.social · 12/03/2026what function is the biggest jumpscare to you. i'll go first, clear choice for me at least it's obviously the gamma function. 3210718 107
doctor eek (alt decorative ghost season) @absolutely-not.bsky.social · 12/03/2026the normal function is a lie and i won't teach it 130 3
Joe Simons @joesimons.bsky.social · 12/03/2026You can't trust it. Just look what happens when it gets it's way. 110 1
Simon Toussaint @simontoussaint.nl · 12/03/2026Even worse is the (upper or lower) incomplete gamma function 110 1
Andy Timm @andytimm.bsky.social · 12/03/2026The number of ways/places the normal distribution can pop up occasionally spooks me. Very strong “are you following me or do we just go all the same places” vibes 140 4
tj nightmahr 🧟♂️ @tjmahr.com · 12/03/2026gotta be gamma because you'll be watching a youtube video like "what is fact(1/2)? is that even possible???" and they lure you in until the jumpscare happens 140 4
Tony Corke @matterofstats.bsky.social · 13/03/2026Surprised the Cauchy hasn't received a mention It looks so innocent but doesn't even have an MGF for a friend 121 2
Thomas Durfee @thomasjdurfee.bsky.social · 12/03/2026I don't trust the Poisson function. Something's fishy about 'em. 040 4

Clint Harris @clintent-to-treat.bsky.social · 12/03/2026Gotta go with Yi(D,Z) a la AIR '96. Gotta put some assumptions on those potential outcomes. 010 1
backyard @bdlurk.bsky.social · 25/04/2026the fact that sin:\C—>\C is unbounded is always a nice one 100 1
Martin Modrák @modrakm.bsky.social · 12/03/2026More of a slow, creeping horror than a jumpscare, but I'll go with the Devil's staircase (Cantor function). Because it is a CDF of a distribution that cannot be described by a (mixture of) density or mass en.wikipedia.org/wiki/Cantor_... 270 7
Seth Axen 🪓 @sethaxen.com · 12/03/2026Literally every function that is non-integrable. They have evil intentions, and I don't trust them. 1100 10

davidcse.bsky.social @davidcse.bsky.social · 13/03/2026inverse ackermann - I came to compsci from an econ background and then learnt about this disturbing function's existence. 021 2
Carlos Scheidegger @cscheid.net · 12/03/2026The wavelet basis functions one gets from Daubechies’s lifting schemes make *no sense* and are eldritch horrors. It’s the best example I know of beautiful math generating horrible functions. Look at D4: 1191 19

Gary Cornwall @garycornwall.bsky.social · 12/03/2026Not a specific function but when I have Mathematica solve an equation for me and the result includes (known) functions I have never heard of before. Makes me wonder if I actually know anything at all. Some of them just look scary enough that I quit. 110 1
