Von der Position aus sind es nur ein paar kleine Schritte zu „kritische Wissenschaft verhindert Fortschritt und Wohlstand“

Being back in the Philippines:

I'm happy to announce that over the last 10 years, the median guess of my age has only increased by 5 years!

It is now 10 years below my true age.

German phone "service" provider while I travel abroad:
1. telling me to book a data package by sending a free SMS
2. I send an SMS
3. SMS cannot be delivered
4. It needs a call to get the data
5. SMS is billed

Ein Screenshot von der Webseite des Wettbewerbs, der einige der tollen Preise zeigt. Der Hauptpreis ist ein 3D-Drucker, ein bionischer Hund ist der Sonderpreis. Außerdem gibt es ein digitales Mikroskop, 3D-Doodler, ein Chemie Experimentierset und eine Cyborg-Hand zu gewinnen.

Mal was Schönes und Unterstützenswertes:

Der Kreativwettbewerb "Frauen in MINT" für 5.-9. Klassen in NRW läuft!

▶️ Sichtbarkeit von Vorbildern erhöhen, Interesse wecken, die Bedeutung wissenschaftlicher Innovationen hervorheben.

Bitte an Lehrkräfte weiterleiten!

As an EU citizen, am I allowed to buy this? And if yes, should I?

THREAD: I'll fact-check all the viral misinformation about the US military operation in Venezuela in this thread

This image, purporting to show the US military arresting Venezuelan President Nicolas Maduro, is AI-generated.

According to Google's SynthID detector, it was created using Google AI.

Mein 2025 Highlight: die technische Uni führt eine Beihilfe-App ein.

Vorher: jede Rechnung sortiert nach Datum in ein Word-Dokument eintragen, mit Betrag, Art der Rechnung,... Dann noch alle Rechnungen in Kopie beilegen und schon kann's per Post verschickt werden. Erstattung ca 3-6 Monate später.

"28 more effective than cash transfers in a baseline scenario and 3732 (!!!) times in an optimistic scenario"

It's early in the evaluation process, but still:
Malengo is such a cool program!

I think there are worse norms, but I was also socialized here 🤷🏻‍♀️

I'm not sure. I think in Germany, there is a social norm to gift something in certain occasions to say thank you. It will hence be expected by the median person (organizers, audience, and the person to thank).

Last weekend, I received a bottle of alcohol-free wine for the first time as a thank you-gift. That was a nice surprise (I don't drink, either).

Academic job markets are weird:

You are sad and disappointed when you don't get the job you interviewed for, but you are also happy for the person who got it (as you usually know them quite well).

Effektiv Spenden | Besser spenden mit Experten Auf Basis wissenschaftlicher Studien und Analysen unabhängiger Experten empfehlen wir die weltweit wirksamsten Hilfsorganisationen.

"Da hast du jetzt eher uns rekrutiert als umgekehrt."

Evtl habe ich gerade den beiden Fundraiserinnen, die an unserer Tür geklingelt haben, so eindrücklich von Effektiv Spenden erzählt, dass sie von dem Konzept ganz angetan waren.

Just to be clear:

I expect a contrast in the polishedness of the papers, simply because: have you ever written a more polished paper than your job market one?

For the talks: I will still need to put mine together, so that's another thing to find out tomorrow.

Either way, it will be interesting!

Screenshot of the email announcing Visilisa's talk, "Destructive Communication" with headshot, affiliation, title and abstract.

The abstract reads:
"Does communication always promote socially efficient behavior? We challenge this common proposition by showing that communication becomes destructive in polarized contexts. In an online experiment, we investigate what happens when participants who fundamentally disagree communicate. We exogenously vary the degree of polarization and the participants’ ability to communicate. When participants are sufficiently polarized, communication no longer improves trust and significantly reduces trustworthiness. Using natural language processing and supervised machine learning, we document that a substantial fraction of participants focus their communication on being polarized, leading to a destructive effect on both trust and trustworthiness. Our findings challenge the universality of contact theory, highlighting that communication may backfire in settings where parties hold opposing views."

Screenshort from the seminar announcement email with title "Individual Preferences for Truth-Telling", abstract and headshot of Lisa. 

The abstract reads: 
"Contrary to the traditional economic view that individuals misreport private information to maximize material payoffs, recent evidence highlights robust preferences for truth-telling among many decision-makers. Theoretical models that align with aggregate behavioral patterns posit that these preferences arise from both an intrinsic motivation to be honest and a desire to be perceived as honest. We propose a novel incentivized measure to independently capture these two motives at the individual level for the first time. We validate the measure’s properties experimentally and show that it predicts behavior in other commonly studied situations that allow for (dis)honesty. The measure enables the classification of individual preference types, revealing systematic heterogeneity and fairly stable type distributions across different samples. Additionally, we propose an experimentally validated 2-minute survey module that proxies both motives and predicts behavior in a typical reporting task. Including this module in a large panel, we offer first insights into how early-life experiences may shape preferences for being and being seen as honest."

How strong are contrast effects?

Join us at the U Penn seminar and find out:

After @vasilisawerner.bsky.social presents her super-polished (former JM) paper, "Destructive Communication", I will present "Individual Preferences for Truth-Telling".

Tomorrow, 7 pm CET. Registration: shorturl.at/mD1qe

If the email of the company your employer hired to teach you about phishing looks so suspicious that you delete it immediately...

...and your employer first notifies you about this upcoming training more than an hour later...

...it will surely be a very successful training!

There is ongoing research about this:

The Gender of Opportunity: How Gendered Job Titles Affect Job Seeker Attraction Paul M. Gorny, Petra Nieken, and Martin Trenkle

From what I remember, they find no overall treatment effect but treatment effect heterogeneity by sector.

Ja und nein.

In Deutschland sind die Unis eine eigene Welt.

Unis im Ausland können auch anders: In England habe ich einmal am Tag meines Vortrags das Angebot bekommen.
