A growing program in political philosophy champions social experimentation as a way of justifying normative principles. But a clear methodology of how social experiments can justify normative principles has not yet been developed in full. We reconstruct and assess two existing methodologies, before developing a third methodology. A first methodology — *evidential experimentalism* — claims that experiments provide justification by generating evidence for what “works.” This is plausible but doesn’t depart as far from mainstream political philosophy as some of its proponents may hope. A second methodology — *iterative experimentalism* — claims that experiments can, over time, justify initially controversial normative principles. But, we argue, iterative experimentalism is susceptible to a regress problem. We develop a third methodology — *procedural experimentalism* — that shifts the attention of normative theorizing significantly but avoids the regress problem. Procedural experimentalism is a variant of procedural justification at the level of mid-level normative principles. We illustrate this methodology using a case study about central banking. This type of justification is widely applicable across the administrative state but has, so far, been overlooked. Johannes Himmelreich https://www.maxwell.syr.edu/directory/johannes-himmelreich Associate Professor Department of Public Administration and International Affairs Syracuse University **About the Speaker:** Himmelreich works on applied ethics and political philosophy. Himmelreich's research asks how artificial intelligence and data science can augment human judgment. Two questions drive this work: How should AI systems be governed? What does it take for data science to lead to better decisions? Himmelreich co-edited the *Oxford Handbook of AI Governance* (Oxford University Press) and has published on algorithmic fairness, the ethics of autonomous vehicles, and collective responsibility in leading philosophy and public affairs journals. His current book project, *Good Decisions*, is supported by a grant from the National Endowment for the Humanities. Beyond this interest in ethics and technology, Himmelreich has also published on the commodification of asylum-provision services as well as on the foundations and nature of moral responsibility and blame. He argues that corporations, states and autonomous systems are agents that can be morally responsible for their actions. Prior to joining Syracuse University, Himmelreich was a postdoctoral fellow at Stanford University from 2017-19. During his time in Silicon Valley, he consulted on tech ethics for two Fortune 500 companies, taught ethics and worked on the ethics of autonomous systems at Apple Inc. He holds a PhD in philosophy from the London School of Economics. **\* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \*** This is a talk with audience Q&A presented by the University of Toronto's Centre for Ethics that is free to attend and open to the public. The talk will also be streamed online with live chat here [to be posted]. About the Centre for Ethics (http://ethics.utoronto.ca): The Centre for Ethics is an interdisciplinary centre aimed at advancing research and teaching in the field of ethics, broadly defined. The Centre seeks to bring together the theoretical and practical knowledge of diverse scholars, students, public servants and social leaders in order to increase understanding of the ethical dimensions of individual, social, and political life. In pursuit of its interdisciplinary mission, the Centre fosters lines of inquiry such as (1) foundations of ethics, which encompasses the history of ethics and core concepts in the philosophical study of ethics; (2) ethics in action, which relates theory to practice in key domains of social life, including bioethics, business ethics, and ethics in the public sphere; and (3) ethics in translation, which draws upon the rich multiculturalism of the City of Toronto and addresses the ethics of multicultural societies, ethical discourse across religious and cultural boundaries, and the ethics of international society. The Ethics of A.I. Lab at the Centre For Ethics recently appeared on a list of 10 organizations leading the way in ethical A.I.: https://ocean.sagepub.com/blog/10-organizations-leading-the-way-in-ethical-ai

You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**DANFORTH WALK, BUTTERFLY MURAL & GREEK LUNCH️** Street Culture, Public Art & A Proper Greek Feast There’s something about the Danforth that feels like old-school Toronto in the best possible way — vibrant, layered, proudly local, and full of stories. Join us for a social walk along one of the city’s most iconic stretches: **Danforth Avenue**. As we stroll west toward downtown, we’ll pass lively patios, long-standing family restaurants, cozy cafés, independent shops, and the everyday rhythm of a neighbourhood that has shaped Toronto’s cultural identity for generations. This area is famously home to the annual **Taste of the Danforth**, one of the largest street festivals in the city — and historically, it was once home to the largest Greek community outside of Greece. You feel that history in the bakeries, the signage, the music drifting from open doors. It’s not just a walk. I t’s a little slice of Toronto heritage — experienced together. **Don’t forget to join our WhatsApp group** – [CLICK HERE!](https://chat.whatsapp.com/H59mSCbsAi018gYANrKAnc?mode=ac_t) \*\*\* The Butterfly Mural Stop Along the way, we’ll stop at the Butterfly Mural, sponsored by the **David Suzuki Foundation** as part of The Great Canadian Butterflyway Project. It’s bold, colourful, and rooted in environmental awareness — a reminder that even in the middle of the city, we are connected to something larger. We’ll pause, take photos, chat, and enjoy a little moment of art-meets-nature in urban Toronto. \*\*\* ️ Greek Lunch at a Danforth Institution After our walk, we’ll sit down for lunch at the historic **Astoria Shish Kebob House**, one of the most well-known Greek restaurants in the city. Expect: Classic souvlaki Lemon potatoes Fresh Greek salad Big, generous comfort food energy Menu: Click Here! Nothing bonds people like sharing a table and passing the tzatziki. \*\*\* ‍♂️ What to Expect We’ll walk at a relaxed, social pace — stopping to observe, chat, and enjoy the neighbourhood. The route will take us toward Danforth & Chester. You’re welcome to leave at any time. \*\*\* ❄️ Weather & Commitment Please don’t sign up if you’re not ready to walk in real winter conditions. This event happens rain, snow, or classic Toronto wind. The only exception: if temperatures reach -20°C, the event will be canceled.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
