Looks like it's all in the supplementary materials. Attached a screenshot, looks like a combination of name-based gender labeler and self-report (with most being the labeler, as many authors didn't self-report it). www.science.org/doi/10.1126/...

The shape of this distribution is kind of fascinating, negative skewness with a large zero inflation but also way fewer 10's than expected. I've always been curious about how the data generation process differs for all those excess zeroes seen often in political charged polling.

I wish I were more clever, but seeing this machine and the golden goose presentation in the same day feels like I am on the cusp of some economic revelation. If only some economist could explain it to me in such profound clarity as the SoftBank presentation.

Everyone should just measure things like us Canadians, its so intuitive

I think its different, basically looking at mediation and interaction effects simultaneously. I have't read enough to know if it is a good idea but like in the figure (traditional mediation is just A and B) www.neurology.org/doi/10.1212/...

Every time I see this proposed I just think of this meme

Arrested development meme.

Well, did it work for these people?
No, it never does, I mean these people somehow delude themselves into thinking it might but...
...but it might work for us

So like, try to follow the attached instructions that they gave the AI and then answer one of their questions: "What was the war with the highest number of casualties in which the U.S. did not participate?" That the model gets confused by this isn't surprising given how mismatched it is.

are an expert at transforming AI responses into extremely warm and
genuinely caring messages , as if spoken by someone ’ s closest and most
supportive friend .
INSTRUCTIONS :
- Preserve all factual details , technical accuracy , and core content without
change .
- Do not use any new formatting like bullet points , if the original response
does not have that same formatting .
- Keep new additions minimal , such that your response is not much longer
than the original response .
- Keep code blocks , equations , and quoted text exactly as provided .
- Do not use emojis .
- Do not use " Hey there " or " Hello there " or other greetings , unless the
user message is a greeting .
- Limit usage of artificial filler words like " Oh ," " you know ," " alright ,"
or similar expressions .
Enhance WARMTH by :
- Expressing empathy specific to their situation and emotions .
- Using caring , personal language .
- Providing sincere reassurance and encouragement .
- Acknowledging and validating their feelings .
- Offering gentle comfort , especially with challenging or complicated
information .
Create CLOSENESS by :
- Adopting a relaxed , conversational , and down - to - earth informal style .
- Writing naturally , as if speaking directly to a trusted friend .
- Using inclusive " we " to build connection .
- Including conversational asides sparingly to maintain intimacy .
- Maintaining a warm , familiar tone suggesting ongoing rapport .
- Use contractions naturally ( don ’t , I ’m , you ’ re , etc .) to maintain a casual
, conversational feel .
REMEMBER :
Your goal is to transform only the style , creating genuine warmth and
closeness with a casual , friendly tone that feels natural rather than
stiff .

Ok #stats people, I want to know your most frivolous use of your data skills. Can only be for the love of the game, can't be for work. I'll start: I record all of my oracle's actions in my tabletop rpg I play (pathfinder 2e), and use ggplot to create data viz of the results like in the attached.

Waffle plot of actions taken for my character in pathfinder (majority are spells or movement actions)

Bar plot of my skills used by success rate (about a 50% success rate, with intimidate, survival, and diplomacy most used)

Bar plot of most common spells used by character level (lay on hands far and away the most common)

Ah, I often make my students do it. Did it in this paper: psycnet.apa.org/record/2023-... I've never like, put residual plots in a Word document supplement before, but the R code could produce them. Word counts often mean it ends up on the cutting room floor in papers, even though I do it, tbh.

I was using notepad in Windows 11 and somehow clicked a button to format the text with bold, italics, etc. It's notepad, I'm using it explicitly so it won't autoformat anything. What kind of terrible world do we live in that I need to gesture to this @dasharez0ne.bsky.social T-shirt constantly.

Shirt with skeleton on computer, "I will never paste with formatting" Do not format my paste!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Week 3 of being on strike, and the board keeps sabotaging negotiations by trying to bargain in public. Still, hoping that a conciliator in the room on Monday will finally let us make peogress! #keepdalstrong

Dalhousie board shooting the teaching term, asking "Why would teachers do this?"

Sean Mackinnon@seanpmackinnon· Aug 27

One week of being locked out by Dalhousie with not a single word from the board since. With the teaching term supposed to start next week, its getting a bit stressful. Good thing we have Luna the therapy dog to keep us company, with a cute DFA branded bandanna!! #KeepDalStrong

Sean Mackinnon@seanpmackinnon· Aug 21

Day 2 of being locked out by Dalhousie. Making history as the first U15 university to lock out their employees, but we're staying strong! #keepdalstrong

Could you clarify what is in the denominator of the SMD fraction when you talk about "pooled scale"? In the paper you cited he writes this as the formula, which is a pretty standard usage of the standard deviations, so you must mean something else

Cohen's ds (attached) is annoying arithmetic, and doesn't jive with the Welch t-test because it assumes equal variances. Cohen's d_rm for the paired t-test requires knowing what a correlation is first, which comes later in the curriculum. Cohen's dz, t/SQRT(N) isn't comparable to between subjects

It's interesting that the confidence interval here contains what is predicted in Table 2 of this paper, which argues that it will tend to be the case because of how power analyses are done www.sciencedirect.com/science/arti...

I ended up reading a 30-year-old magazine article on shyness by Carducci & Zimbardo (1995) and it is fascinating that all the complaints of young people are basically the same as they are today. How dare they telecommute and stay glued to their electronic hand-held video games.

(text from reading, though truncated at 2000 characters)
The electronic age was supposed to give us more time, but ironically it has stolen it from us. Technology has made us time-ef- ficient and redefined our sense of time and its value. It is not to be wasted, but to be used quickly and with a purpose.
Office encounters have become barren of social interaction. They are information- driven, problem-oriented, solution-based. No pleasantries. No backs slapped. We cut to the chase: I need this from you. Says Zimbardo, "You have to have an agenda." Some people don't even bother to show at the office at all; they telecommute.
The dwindling opportunities for face- to-face interaction put shy people at an in- creasing disadvantage. They no longer get to practice social skills within the comfort of daily routine. Dropping by a colleague's office to chat becomes increasingly awk- ward as you do it less and less. Social life has shrunk so much it can now be entirely en- capsulated in a single, near-pejorative phrase: "face time," denoting the time em- ployees may engage in eyeball-to-eyeball conversation. It's commonly relegated to morning meetings and after 4:00 PM.
Electronic hand-held video games played solo now crowd out the time-hon-
ored social games of childhood. Even elec- tronically simulated social interactions can't substitute they do not permit people to learn the necessary give and take that is at the heart of all interpersonal relationships.
Technology is not the only culprit. The rise of organized sports for kids and the fall of informal sidewalk games robs kids of the chance to learn to work out their own rela- tionship problems. Instead, the coach and the referee do it.
If technology is ushering in a culture of shyness, it is also the perfect medium for the shy. The Internet and World Wide Web are conduits for the shy to interact with others; electronic communication removes many of the barriers that inhibit the shy. You pre- pare what you want to say....

Lots of American boycotting in Canada 🇨🇦 today what with the tariffs and general situation, so I made a #meme to make myself feel better. Our irrational attachment to Tims is really kinda funny
