First Date: Singapore's government dating app

The government of Singapore is rolling out a dating site, initially as "A pilot for public officers only."  It infers preferences from questionnaire responses, and uses the deferred acceptance algorithm to produce one match per participant in each match run.

Here it is: FirstDate.
"Start something real.
An initiative to support singles aged 21-35 in their dating journey, verified using Singpass."
"Find your match.  Applications close on 05 Oct 23:59" 

"Swipe fatigue ends here. Receive one match at a time, so you can focus on building a thoughtful connection.

"Designed with your privacy in mind. Only your match sees your profile, and you decide if your contact details are shared. 

...

"What is FirstDate?
"FirstDate started with a question among a group of GovTech officers: does having more potential matches necessarily make it easier to find a suitable match?

"The team shared an interest in exploring some of the challenges people can face when meeting someone new. They wondered whether a different approach that places greater emphasis on compatibility through values and preferences, and offers fewer matches at a time, could give users more space to consider each introduction and decide whether they would like to take the next step. They explored the idea at GovTech Singapore's annual {build} hackathon, where officers develop and test new ideas.

"That idea became FirstDate, a ground-up pilot initiative currently being tested across Public Service.


"How does the matching work?
FirstDate uses your questionnaire responses, including your interests, habits, values and preferences, to understand what you're looking for in a potential partner.

"It then applies the Gale-Shapley Stable Marriage algorithm, an established mathematical approach that generates pairings based on participants' preferences to recommend matches based on compatibility."

Here's some  coverage from Singapore Samizdat:

How Singapore’s government-run dating service works, and why it won’t solve the nation’s dating woes
Here are the 30+ questions in the matchmaking tool that Singapore is deploying to solve the incel problem. 

"Three years after the demise of the Social Development Network, it looks like a new government-run matchmaker is back on the cards for Singapore.

Earlier this month, a pilot progamme by GovTech called FirstDate was announced, with government workers set to be the first batch of daters. If this sounds familiar, that’s because I was the first to report on GovTech testing the waters with this idea all the way back in April for The Straits Times."

Ukraine weighs legalizing pornography to raise tax revenue and buy drones

 Here's a story from the WaPo whose headline already conveys a lot about the economics of tradeoffs:

Ukraine weighs legalizing pornography to raise tax revenue and buy drones
Facing a massive defense budget shortfall, Ukraine has not been able to cash in on the millions of dollars earned by its clandestine adult-content industry. By Francesca Ebel and Anastacia Galouchka
 

"KYIV — For years, Ukraine’s huge but illegal porn industry has operated in the shadows. Law enforcement generally looked the other way, while some officials abused their power to extort bribes from people found to be skirting the law.

"Then, two years into Russia’s full-scale invasion, the federal tax authorities discovered that nearly 8,000 Ukrainian OnlyFans creators had made more than $131 million during 2023 alone.

"Now, with Ukraine facing giant military expenses and a $27 billion budget gap, lawmakers are moving to decriminalize pornography — a momentous step for a country long stained by a reputation for exploiting and exporting women as sex workers. 

...

"Raising money on the backs of adult-content creators, however, is a fraught proposal in Ukraine, where the women’s protest group Femen rose to worldwide fame by demonstrating topless to decry sexual exploitation and patriarchal authoritarianism.

"Critics of the bill fear that it could undermine public morality, as well as increase the risk of human trafficking and child sexual abuse. 

...

"Supporters of legalization say that it will protect women, not encourage abuse.

“Human trafficking is based on coercion: A person is deceived; their documents are taken away,” Oksana said. “The modern creator economy is completely different. An adult woman verifies her identity and age on the platform and determines her own boundaries.” 

Iran's kidney market, reviewed in Al-Madina: Journal of Islamic Law

The new English language journal Madina: Journal of Islamic Law has, in it's inaugural issue, a literature review of the Iranian kidney market. (It appears only to have reviewed papers that were also published in English.) The title summarizes the conclusion, that the market aligns with the goals of Islamic law.

Faisal, Ahmad, Abdul Khakim Mahfud Zubaidi, Ahmad Nizar Zuhdi Al Hakimi, and Roya Goldoust. “The Iranian government’s efforts to facilitate foundation-led kidney donation align with the Maqāsid al-Sharī’ah.” Al-Madina: Journal of Islamic Law 1, no. 1 (2026): 28–48. 

Abstract
The issue of kidney transplantation, particularly through compensated living-unrelated donors, represents a complex intersection of medical necessity, ethical debate, and international governance. Iran is unique in legally regulating compensated kidney donation, aiming to address the chronic shortage of transplantable organs while providing structured financial incentives to donors. This study analyzes Iran’s
kidney donation system through the lens of maqāsid al-sharī’ah, emphasizing the objective of hifz al-nafs (preservation of life), to evaluate both the ethical legitimacy and life-saving effectiveness of the policy. Employing a qualitative-descriptive approach, the research synthesizes empirical evidence on donor demographics, motivations, compensation mechanisms, and clinical outcomes, alongside normative Islamic ethical considerations and international standards such as the WHO Guiding Principles and the Declaration of Istanbul. Findings reveal that while Iran’s system significantly enhances patient survival and fulfills the core goal of hifz al-nafs, donor participation is heavily influenced by economic necessity, raising ethical concerns about voluntariness, long-term welfare, and equitable access. Moreover, the system’s interaction with foreign patients highlights challenges in cross-border governance and the potential for transplant tourism. The study contributes academically by integrating empirical outcomes with Islamic normative ethics, and practically by offering insights for policymakers, religious authorities, and international health organizations on navigating the tension between life preservation, ethical legitimacy, and socioeconomic realities. The research underscores that while the Iranian model demonstrates pragmatic life-saving benefits, ethical safeguards for donors must remain central to uphold the objectives of maqāsid al-sharī’ah."

Organ trafficking research

 Frederike Ambagtsheer is the principal investigator of a Dutch project conducting organ trafficking research, whose website discusses their work:

welcome to organ trafficking research

This platform presents research projects on the human organ trade that are conducted by Erasmus MC's Organ Trafficking Research Group. We further provide information for interested audiences (e.g. students, researchers, law enforcement, law -and policy-makers, etc) about the complexities of this crime and the responses there-to.

The organ trafficking research group is based at Erasmus MC's Department of Internal Medicine, Section Nephrology and Kidney Transplantation in Rotterdam(opens in new tab), The Netherlands. This department is part of the recently established Erasmus MC Transplant Institute (opens in new tab)which houses one of the largest kidney transplantation centers in Europe.

...

what we do

We are an enthusiastic and dedicated team of researchers that conduct empirical research on different facets of organ trade and trafficking. Our research is structured into various projects. Methods include a mix of qualitative and quantitative research strategies including systematic literature reviews, surveys, ethnographic research, crime scripting and network analysis.

We conduct research in countries across the globe and we focus on all stages of the organ trading chain, including organ buying, selling, the organisation of illegal transplants and law enforcement responses. We also explore alternative measures such as allowing financial rewards for organ donation. In addition, we advise governments and (inter)national organizations on how to address organ trade problems.

Our research is funded by organisations including the European Commission, the European Research Council and the Dutch Research Council (NWO)."
