dplyr but make it bussin fr fr no cap

`genzplyr` is an alternative syntax for `dplyr` that replaces boring old function names with GenZ slang. Your data wrangling is about to hit different.

Can AI-generated images work as visual vignettes in survey experiments? I argue yes - and discuss how . in my new @sscratsage.bsky.social paper: doi.org/10.1177/0894...

Two AI generated images showing 1) a boy walking through a disorderly neighbourhood with graffiti and trash and 2) a boy walking through a very similar but cleaned up neighbourhood without trash ad graffiti.

Any experiences with data donation of #Spotify listening history?

I requested to download my full listening history and it said that it would take 30 days to produce the download.

2 hours later I received the link to the zip file with full JSON records.

Any other experiences with this?

"Representative sample" is a flawed, ambiguous concept and it does not have a precise definition in the technical literature of survey sampling, so you should avoid using it at all costs.

Selbstselektion & Mehrfachteilnahme unterminieren Grundlagen seriöser Stichprobenlogik.
Eine nachträgliche Gewichtung kann diese systematischen Verzerrungen nicht kompensieren.
Dass der ORF eine solche Umfrage als inhaltl. Aufhänger nutzt, ist methodisch & journalistisch fragwürdig & enttäuschend.

Screenshot: https://www.orffragt.at/index-ende.php

Zur Umfrage

Die Online-Umfrage „ORF fragt“ fand von 17. September bis 8. Oktober 2025 statt. Als Teil der ORF-Dialog-Offensive waren alle Menschen in Österreich eingeladen, dabei mitzumachen und ihre Meinungen zu alltagsrelevanten Themen abzugeben. Insgesamt beteiligten sich rund 80.000 Personen – Basis für die Auswertung waren dann 77.684 Interviews mit Personen, die laut eigener Angabe in Österreich wohnen und mindestens 14 Jahre alt sind. Inhaltlich begleitet wurde die Umfrage vom Markt- und Meinungsforschungsinstitut INTEGRAL, das auch die Auswertung durchgeführt hat. Aufgrund der Anlage der Umfrage – jeder, jede Interessierte konnte sich online daran beteiligen – wurde keine Stichprobe nach strengen wissenschaftlichen Kriterien gezogen, weshalb die Ergebnisse nicht repräsentativ für die gesamte österreichische Bevölkerung sind. Die Ergebnisse wurden aber nach soziodemografischen Merkmalen (z. B. Alter, Region) gewichtet, um sie an die tatsächliche Verteilung in der österreichischen Bevölkerung anzupassen.

These companies must be using the same crazy survey provider. What is this?!

Survey with the question "How likely are you to recommend [solidcore] Durham to a friend or colleague?" Options 0-10 are arranged in a very bizarre order with 0 at the bottom 1-9 in three rows with numbers starting on the right on each row, and a much bigger 10 button on top.

(2) All other authors on the cited paper did not work on that paper, although I have multiple other papers with them (except one). And (3) the journal is not correct. (3/3)

Florian Keusch @floriankeusch.bsky.social · Oct 2

I am a co-author on a paper with that exact title, but (1) a PhD student is the first author (not I as the cited reference says) and there is another coauthor - both are not on the cited paper. (2/3)

Florian Keusch @floriankeusch.bsky.social · Oct 2

Had only heard about this from others, but now it happened to me: got a citation alert (from ResearchGate) and found that the paper the authors cite does not exist (at least not in that form). (1/3)

...PA data donation worked (very) well, especially for iPhone owners between 50 and 70 years; less so for Android phone owners and people >70. Nonparticipation correlates strongly with characteristics of smartphone ownership, comfort with smartphone use, and health status #HealthyDonorBias.

I gave a talk at ISR yesterday on declining response rates in surveys, and why we should not automatically assume that this means our survey estimates will be subject to nonresponse bias. Here is the recording for anyone interested! Thanks again to ISR Insights. 🙏
