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

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

I present to you the ultimate filing cabinet for old and resting (let's be honest: abandoned) projects, well hidden under a staircase in the back entrance of a local government office.

I guess the same as with the papers showing gender bias in the publication process and teaching evaluations: nothing. When I pointed out this research on teaching evaluations at the start of my tenure track, it was just ignored. I still have a target score above which I need to be evaluated.

Screenshot of title, authors and abstract of a journal article published in the Journal of the European Economic Association.

Title: Gender Bias in Teaching Evaluations
Authors: Mengel, Sauermann, Zölitz

Abstract: This paper provides new evidence on gender bias in teaching evaluations. We exploit a quasi-experimental dataset of 19,952 student evaluations of university faculty in a context where students are randomly allocated to female or male instructors. Despite the fact that neither students’ grades nor self-study hours are affected by the instructor’s gender, we find that women receive systematically lower teaching evaluations than their male colleagues. This bias is driven by male students’ evaluations, is larger for mathematical courses, and particularly pronounced for junior women. The gender bias in teaching evaluations we document may have direct as well as indirect effects on the career progression of women by affecting junior women’s confidence and through the reallocation of instructor resources away from research and toward teaching.

Just had a MS Teams meeting with one additional "participant" that nobody knew how to get rid of. So it listened to our call and just sent a summary (not that bad) + some metrics. The meeting was 82 effective! (to me, longer than necessary) Now I wonder how all my other meetings compare.

Screenshot from an email that shows metrics of the meeting. It lists a read score (82), an engagement score (91) and a sentiment score (73).

4️⃣ design an unincentivized survey module that - captures both cost types - correlates with our experimental measure - is predictive of behavior in the mind game - takes two minutes to complete 6/7

Screenshot of a slide that presents the survey module.

`Please imagine the host of a live radio show calls you to participate in a radio raffle. Your task is the following: you must flip a coin 4 times and report the number of `tails' you flipped. You will receive 10 pounds for each reported `tail'. You know that there is no way the host can verify whether you reported the true number of `tails' you flipped.'

Imagine the unlikely case occurs that you flip 0 tails.
How many tails will you report to the host?

Imagine the unlikely case occurs that you flip 4 tails.
How many tails will you report to the host?

3️⃣ demonstrate the measure is - internally valid (using treatments that vary the costs) - predictive of behavior in other commonly used experimental honesty paradigms Example below: mind game in which participants whom we classify as having low ILC and low SIC claim larger payoffs. 5/7

The figure consists of four panels and shows the distribution of claimed payoffs in the mind game by IPT types in the student sample (n=331).

Lisa Spantig @lisaspantig.com · 23/12/2024

2️⃣ classify four main preference types 1) low ILC & low SIC 2) low ILC & high SIC 3) high ILC & low SIC 4) high ILC & high SIC and document substantial heterogeneity in types across three different samples: - student sample, - convenience sample, and - UK representative sample. 4/7

Bar chart of type distribution across the three samples. All four types are present in the three samples. The most prevalent type has low ILC and high SIC. The least prevalent type has high ILC and high SIC.

Behavioral/experimental #EconSky with interest in honesty: Our working paper is finally here! "Individual Preferences for Truth-Telling" - with @simeonschudy.bsky.social and Susanna Grundmann. First, here is what ChatGPT imagines it is about. Now, let me tell you what we actually do. 1/7

AI generated picture based on the following prompt: "A person stands at a forked path under a softly lit sky. On the left path, labeled “Truth,” bright light radiates forward, leading to an open horizon. On the right path, labeled “Falsehood,” shadows and twisting vines coil, hinting at uncertainty. Above the individual’s head, a subtle thought bubble or glowing scale tilts slightly in favor of truth, suggesting their preference or internal struggle. The person’s face appears reflective yet determined, conveying the choice to speak honestly even amidst potential conflict or complexity.

Stylistically, imagine gentle, yet vivid colors—warm golds and cool blues—to emphasize the moral dimension of telling the truth. Incorporate symbolic elements like a feather (lightness of truth) and a chain (weight of falsehood). The overall composition should evoke the tension and reflection involved in deciding to uphold honesty."

Why can't all countries have such a smooth visa application process like 🇰🇪? No "passport-style" photo? Take a selfie, and the software adjusts it. Can easily be completed in <10 minutes, response usually in <72 hours. Yes, looking at you, 🇩🇪...such a long list of requirements. For the photo.

Screenshot of the visa photo requirements for Germany stating the following:

The photo should meet the following requirements when applying for Germany visa:

The photo size should be 35×45 mm or 1.37×1.77 inches.
The photo should have been taken in the last six months.
Your face should take up 70-80% of the picture.
Full frontal view of the face must be displayed in the photo.
The photo should be of high quality and accurately represent your true appearance.
The background of the photo should be light grey.
The photo should be sharp-focused, clear and properly contrasted.
Red eyes, reflections in the photo and shadows across the face are not permitted.
Lighting must be even (not too dark, not too bright).
The image is to be printed on a high-quality paper, either glossy or matte.
Print resolution of the photo must be 600 dpi minimum.
The German embassy requires 2 identical photos to be submitted.
