The culmination of nearly a decade of work: my new paper with Louise Blight @procellaria11 and Wilson Cao on urban-nesting Glaucous-winged Gulls (GWGUs) of @CityofVancouver now online in Ecological Modelling. I'll give the highlights here, but more to come soon. 1/7

@littmath Have had the exact same conversations with my toddler. She has a Darwin stuffy and she said she wanted to go play with the real Darwin someday. When I explained why she couldn't, she cried for almost an hour. She still brings it up months later randomly that she's sad about it.

Toddler: *looking at dinosaur fossils* Did THEY die? Me: yes, a very long time ago. Toddler: When I was a BABY?!

Toddler: *gestures at 200m-year-old crustacean fossils at Natural History Museum* How did they die? Me: I don’t know. Maybe there was some kind of disaster, or they got really old— Toddler: *stares at me, tears welling up* they died because they got old?

@JoshLipnik Lol I am exactly the same way, but with gulls. Your sacrifice is a noble and appreciated one.

I’ll still be doing the same thing and taking pictures of buildings and signs though. I don’t know how to take an actual vacation.

Pretty excited to go to Arizona tomorrow and not think about the Midwest for a week. I haven’t left since I started doing this almost 8 years ago.

With almost any other valued skill, “ I’m terrible at it. I hate it” is either embarrassing or you'd be expected to explain. With math, people say it proudly across cultures and educational backgrounds Sociologists should study this!

@martinmbauer Disrespect for elementary mathematics across various levels of education, college included, is a uniquely US problem, among developed countries...

@MatthewMKE98 He was awesome. People whined about his overall FG% but the dude NEVER missed a kick that really mattered.

McManus would have hit a cheerleader on the sideline had he attempted this kick Everyone knew Mason Crosby was great and yet someone I dont think we truly appreciated him for his greatness until the shitshow we’ve had to deal with since he retired U could always count on Crosby

Today in 2017: @Buck: "This to send the Packers into the NFC Championship game. It iiiiiisssssss GOOD! The Packers are moving on! Aaron Rodgers has done it again! And Mason Crosby...a hero for Green Bay!"

@zacobson Dude, this is one of the few instances where I'm glad to be older. To miss out on the highs and lows of the GB 90s is a shame. Glad I'm not so old to remember the 80s though.

@IonaItalia It is 100% disconnection from reality, paired with staggering solipsism and insulation from consequences.

"Wrong Way" Corrigan, the man who once flew all the way to Ireland by mistake, died this week at the age of eighty-eight. "It was just like him," said his wife, "He was trying to live."

@HistoricPackers Those years taught me to hate the Cowboys and I've never recovered. I still delight in every loss they suffer.

Packers History
Packers History@HistoricPackers·
For those of you too young to remember: Between 1993 and 1996, the Packers played seven times in Texas Stadium...and lost all seven, including three playoff games. Average margin of defeat: 15.0 points
Packers History@HistoricPackers

Today in 1994: Sterling Sharpe (@Thro284) ties a franchise record with four receiving TDs, but big days by Dallas' Jason Garrett (311 pass yds, 2 TDs) and Emmitt Smith (228 total yds, 2 TDs) result in 42-31 Packer loss in Dallas.

Blame the incentive structure. The more papers you publish and the more students you "train", the easier it is to get bigger grants, course buyouts, prestigious "Distinguished Professor of Blah"ships. There's no way to fix this.
Mathieu@miniapeur

Professors having 50 papers per year is exactly the problem. That’s almost a paper a week. The system is broken because we end up with a few professors clogging all the resources and essentially overseeing paper mills.

Mathematicians better muscle up soon too. I have had at least 5 people (students and faculty) in the past year alone claiming gradient descent is some magical AI/ML innovation. Nothing screams "I have no math training but I pretend to" more than statements like that.

@SarahTheHaider I imagine she has timestamps on her survey responses, so she could create "cohorts" and then examine prop. of trans or whatever for those who took the survey in 2021 vs 2022 vs 2023 etc. It's still all self-recruitment data, but that would at least weakly address the question.

@ed_kroc Thank you, that’s what it seemed like. I didn’t understand her defense of it. I don’t know if her data can say anything much (even weakly).

I wondered the same thing, but as I am not Learned in Data Science, I would love for someone with more insight to pitch in.
Justin Murphy@jmrphy

OK am I nuts? I've heard people say Aella is a legit "data scientist" but I've read this Aella "data analysis" like 5 times and... It seems like the most incorrect data analysis I've ever seen. But Yudkowsky RT'd it with a glowing endorsement and he knows math, so I really need someone to pinch me right now. Like either I'm crazy, or Aella is so gaslit by her simps that all of their brains have gone mushy together. Can someone (who is not an Aella simp) please look real quick and pinch me? I tried asking her in X replies but that did not really help. Her analysis responds to a report by Eric Kaufmann, who presents repeated cross-sectional surveys of college students over a few years (not panel data, different cohorts). Kaufmann's data suggest nonbinary identification among university students increased from 2019 to 2023, then decreased or at least stopped increasing. Aella presents data from her own survey, which is treated as one point in time (submissions have come in over a few years but she pools it into one period for her analysis), in other words, there is no time dimension in her analysis. She presents a graph showing her measure of trans by age and declares, "I don't find a dip. Weird." Am I crazy or... Is she confusing Age with Time? Is that what she's doing?! Like 4 times in a row in multiple analyses? And she does nothing else? If so, this would be the most deeply naive mistake you could ever possibly find in a blog post from someone who identifies as a researcher. Like this would be legendary, the "chart crime" of the decade. If you don't know, there is a difference between AGE (lifecyle), TIME aka PERIOD (calendar years), and COHORT (birth year). Kaufmann graphs a kind of period change. This is what everyone means if they talk about change over time, something increasing or decreasing over time... Like tons of variables just go down over the lifecycle lol. That's all her graphs seem to show. You're more likely to be trans when you're 20 than when you're 70 lol. Duh? These graphs cannot show any decline (or increase), in anything over time, in any way even slightly comparable to the analysis she is attempting to question or challenge or correct. Like her graphs are infinitely structurally incapable of saying anything whatsoever about the object of her analysis. Unless, again, I'm crazy. After this post, she's tweeting how bad professional researchers are and how good she is compared to them. Eliezer Yudkowsky RT'd this post saying "one of Earth's top scientists on sex and gender has published her latest work." So can someone please someone tell me: Am I an idiot, or are Aella and Yudkowsky both idiots?

@CarrierPig @SarahTheHaider Yes, if you are comparing cohorts across time, then that would address the original issue. That does not appear to be what Aella is doing though. As the original QT pointed out, it looks like she has just pooled all her data together; hence, there is no longitudinal component.

Kevin@CarrierPig·
ok I've asked multiple AIs and they give me the same answer that it's a repeated cross sectional study or a trend study, but I don't really want to get into a semantics debate. Doesn't it make sense that a way to cross check if recent college student cohorts (ie 18-22 year olds) are less trans/non-binary than previous cohorts, you could simply see if ~16-19 year olds surveyed over the last few years have lower rates than older cohorts and generally match the absolute rates found in the original study? That seems not crazy to me? There are ofc assumptions/selection effects, but I don't really see why it's "wrong". Eg medical science uses correlational studies, RCTs, basic mechanism research in lab animals - each has its own assumptions and flaws but they build into an entire evidence base that one can then assess
