If I search for tropical cyclones that actually came within 100 miles of New Mexico, I found 16 of them going back to 1916. The most recent was Newton in 2016. This isn't just remnants bringing rain, these are actual data points as tropical cyclones.

AP Stylebook warns against anthropomorphizing AI systems: “Avoid language that gives them human characteristics… Instead, explain what a system does, how well it performs, who built it and who could be affected by it.”
APStylebook @APStylebook
X.com
Artificial intelligence systems do not think, feel, want or understand. Avoid language that gives them human characteristics. This is called anthropomorphizing, when we ascribe human traits, emotions or behaviors to non-human things, such as animals or inanimate objects.
Instead, explain what a system does, how well it performs, who built it and who could be affected by it.

New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵
Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

annals of book research, part one no amount of prior experience in child development can prepare you for this insane 1998 bill from the State of Florida, which REQUIRES state-funded daycares to PLAY CLASSICAL MUSIC TO INFANTS because they have ONE HUNDRED BILLION BRAIN CELLS
Florida Senate - 1998 SB 660
 By Senator Turner
 36-628-98
 1 A bill to be entitled
 2 An act relating to education; providing that
 3 state-funded education and care programs for
 4 infants and toddlers must foster brain
 5 development; requiring an evaluation and a
 6 report; providing an effective date.
 7
 8 WHEREAS, at birth, a child has one hundred billion
 9 brain cells that will be developed by the experiences of life,
10 and
11 WHEREAS, the stimulation that causes brain development
12 can be positive, such as conversation, music, and parental
13 love, or it can be negative, such as neglect or emotional and
14 physical abuse, and
15 WHEREAS, during the first year of a child's life the
16 connections between the cells, the synapses, increase
17 twenty-fold, making the first year a crucial time for brain
18 development, and
19 WHEREAS, infants develop synapses when they listen to
20 language and music, see colors and shapes, and feel and handle
21 objects of different sizes, shapes, and textures, and
22 WHEREAS, there is no other time in a child's life as
23 productive for brain development as the first year, NOW
24 THEREFORE,Be It Enacted by the Legislature of the State of Florida:
27
28 Section 1. Each state-funded education and care
29 program for children from birth to 5 years of age must provide
30 activities to foster brain development in infants and
31 toddlers. A program must provide an environment rich in
 1
CODING:Words stricken are deletions; words underlined are additions.
 Florida Senate - 1998 SB 660

 1 language and music and filled with objects of various colors,
 2 shapes, textures, and sizes to stimulate visual, tactile,
 3 auditory, and linguistic senses in the children and must
 4 include classical music and at least 30 minutes of reading to
 5 the children each day. A program may be offered through an
 6 existing early childhood program such as Healthy Start, the
 7 Title I program, subsidized child care, the prekindergarten
 8 early-intervention program, Florida First Start, the Head
 9 Start program, or a private childcare program. A program must
10 provide training for the infants' and toddlers' parents
11 including direct dialogue and interaction between teachers and
12 parents demonstrating the urgency of brain development in the
13 first year of a child's life.

It's a systemic problem in science reporting that these summaries exaggerate the evidence. In the actual candy study, the participants were all students, status was manipulated in the lab by telling some students they were better than others, and "nearly twice" means 1 piece vs 2 pieces.
Piff and his colleagues found that upper-class drivers were more likely to cut other cars off at junctions and ignore pedestrians at crossings. Wealthier people also appeared more willing to lie at work. In one experiment, volunteers were left alone with a jar of sweets ostensibly meant for children. When the researchers returned, upper-class people had snaffled nearly twice as many candies as lower-class people.

Every time manipulated or fabricated data is discovered, I think of all the studies I ran that could have told an incredibly compelling story if only the results were different. It's also why I've grown skeptical of people described as good "storytellers".

Data Colada's scrutiny was only possible because they got the data. That's why I think that authors who don't share data+materials (and editors who protect those authors by allowing them to not share data+materials) are basically stating that they don't care if the results are misleading.
