Decided to take the kids to this game. They had lots of questions about hockey. 😂 Had a little bit of everything (I’ve never seen a player get ejected before the puck dropped for a face-off!), but I do hope that Ivankovic is OK. Such a bush league play. 🤬

Can someone explain to me, like I’m a first grader, WTH the point is of declaring that you are entering the transfer portal when you simply decide to return less than a week later? Is that really enough time to see what your market value is? Just seems nutty and pointless. 🤷🏻‍♂️

So watching this exhibition, which Michigan football players give you optimism for next year?

1. Andrew Marsh
2. Jake Guarnera

Uhhhhh….

3. Bryce with a real QB coach?
4. A healthy Cole Sullivan with a real DC?

EOL?

Ready to launch your social science career?

ISR’s Junior Professional Researcher (JPR) Program is a full time paid opportunity offering hands on research experience, mentorship from ISR faculty, and professional training at the world’s largest social science research institute.
Promotional graphic for the Junior Professional Researcher Program. At the top left is the program logo with three vertical stripes in maize, orange, and blue, followed by the words "Junior Professional Researcher Program." Below the logo is an orange rounded rectangle with white text that reads, "Looking for opportunities in social science research?" Underneath is a blue box with white text and a checkmark icon that reads, "Explore your future with hands-on, PAID, experience at the world’s largest social science research institute." Below that is a photo of three smiling students seated outdoors with the caption, "Application opens: January 1, 2026." On the right side is a vertical background of repeated dark blue "JPR" text. Over this, a student wearing glasses and an ISR T-shirt that reads “Social Science in the Public Interest” smiles at the camera. At the top right is a circular photo of a group of seven Junior Professional Researchers standing outside in front of the ISR

Rationale scientists are not a thing. Although maybe they should be? 😂

Add this to the list of rationale scientists reading about synthetic sampling and saying “uhhh….what?” 🙄

I really hope that peer reviewers do not accept this as normal practice. This is just so dangerous.

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?

Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"
Text reads: About synthetic panels Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels. Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey. Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away. Text reads: Question-writing best practices To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices: Ask forward-looking and attitudinal questions. Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, “How likely are you to try…?” Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, “When did you last visit…?” Text reads: Discussion The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002) of the variance in behaviour to be explained by intention and PBC.

New U-M survey led by ISR’s Bob Marans and Noah Webster with the Graham Sustainability Institute found that nearly 6,000 students, faculty, and staff across all three campuses report strong engagement with sustainable behaviors and climate awareness.

Infographic titled "Sustainability Cultural Indicators Program (SCIP) 2024" measuring sustainability awareness and behaviors at U-M campuses. It includes circular indicators showing 2021–2024 data for waste prevention awareness and travel behavior (Ann Arbor), and commitment to behavior change (Ann Arbor, Dearborn, Flint), as well as 2012–2024 data for sustainability engagement and commitment. Key findings include high travel behavior scores (students: 8.1) and moderate commitment to carbon neutrality (staff: 7.8 at Dearborn). A color-coded legend shows significant increases or decreases.
