Are Elites Meritocratic and Efficiency-Seeking? Evidence from MBA Students

3 weeks 3 days ago
Abstract of a paper on pre-print server Arxiv: Elites disproportionately influence policymaking, yet little is known about their fairness and efficiency preferences -- key determinants of support for redistributive policies. We investigate these preferences in an incentivized lab experiment with a group of future elites -- Ivy League MBA students. We find that MBA students implement substantially more unequal earnings distributions than the average American, regardless of whether inequality stems from luck or merit. Their redistributive choices are also highly responsive to efficiency costs, with an effect that is an order of magnitude larger than that found in representative U.S. samples. Analyzing fairness ideals, we find that MBA students are less likely to be strict meritocrats than the broader population. These findings provide novel insights into how elites' redistributive preferences may shape high levels of inequality in the U.S.

DHS Has Been Collecting US Citizens' DNA for Years

3 weeks 3 days ago
Customs and Border Protection collected DNA from nearly 2,000 US citizens between 2020 and 2024 and sent the samples to the FBI's CODIS crime database, according to Georgetown Law's Center on Privacy & Technology analysis of newly released government data. The collection included approximately 95 minors, some as young as 14, and travelers never charged with crimes. Congress never authorized DNA collection from citizens, children or civil detainees. DHS has contributed 2.6 million profiles to CODIS since 2020, with 97% collected under civil rather than criminal authority. The expansion followed a 2020 Justice Department rule that revoked DHS's waiver from DNA collection requirements. Former FBI director Christopher Wray testified in 2023 that monthly DNA submissions jumped from a few thousand to 92,000, creating a backlog of 650,000 unprocessed kits. Georgetown researchers project DHS could account for one-third of CODIS by 2034. The DHS Inspector General found in 2021 that the department lacked central oversight of DNA collection.

U.S. News Rankings Are Out After a Tumultuous Year for Colleges

3 weeks 3 days ago
An anonymous reader shares a report: Battered by funding cuts, bombarded by the White House and braced for demographic changes set to send enrollment into a nosedive, America's colleges and universities have spent this year in flux. But one of higher education's rituals resurfaced again on Tuesday, when U.S. News & World Report published the college rankings that many administrators obsessively track and routinely malign. And, at least in the judgment of U.S. News, all of the headline-making upheaval has so far led to ... well, a lot of stability. Princeton University, the Massachusetts Institute of Technology and Harvard University retained the top three spots in the publisher's rankings of national universities. Stanford University kept its place at No. 4, though Yale University also joined it there. Williams College remained U.S. News's pick for the best national liberal arts college, just as Spelman College was again the top-ranked historically Black institution. In one notable change, the University of California, Berkeley, was deemed the country's top public university. But it simply switched places with its counterpart in Los Angeles.

Python 3.13.5 Patch Release Packed with Fixes & Stability Boosts

3 weeks 3 days ago
by George Whittaker Introduction

On June 11, 2025, the Python core team released Python 3.13.5, the fifth maintenance update to the 3.13 line. This release is not about flashy new language features, instead, it addresses some pressing regressions and bugs introduced in 3.13.4. The “.5” in the version number signals that this is a corrective, expedited update rather than a feature-driven milestone.

In this article, we’ll explore what motivated 3.13.5, catalog the key fixes, review changes inherited in the 3.13 stream, and discuss whether and how you should upgrade. We’ll also peek at implications for future Python releases.

What Led to 3.13.5 (Release Context)

Python 3.13 — released on October 7, 2024 — introduced several significant enhancements over 3.12, including a revamped interactive shell, experimental support for running without a Global Interpreter Lock (GIL), and preliminary JIT infrastructure.

However, after releasing 3.13.4, the maintainers discovered several serious regressions. Thus, 3.13.5 was accelerated (rather than waiting for the next regular maintenance release) to correct these before they impacted a broader user base. In discussions preceding the release, it was noted the Windows extension module build broke under certain configurations, prompting urgent action.

Because of this, 3.13.5 is a “repair” release — its focus is bug fixes and stability, not new capabilities. Nonetheless, it also inherits and stabilizes many of the improvements introduced earlier in 3.13.

Key Fixes & Corrections

While numerous smaller bugs are resolved in 3.13.5, three corrections stand out as primary drivers for the expedited update:

GH-135151 — Windows extension build failure

Under certain build configurations on Windows (for the non-free-threaded build), compiling extension modules failed. This was traced to the pyconfig.h header inadvertently enabling free-threaded builds. The patch restores proper alignment of configuration macros, ensuring extension builds succeed as before.

GH-135171 — Generator expression TypeError delay

In 3.13.4, generator expressions stopped raising a TypeError early when given a non-iterable. Instead, the error was deferred to the time of first iteration. 3.13.5 restores the earlier behavior of raising the TypeError at creation time when the supplied input is not iterable. This change avoids subtler runtime surprises for developers.
