Ep 152: Why Relying on Data Can Cause More Harm Than Good

Ep 152: Why Relying on Data Can Cause More Harm Than Good

Cathy O’Neil is a mathematician who has worked as a professor, hedge-fund analyst and data scientist. Cathy founded ORCAA, an algorithmic auditing company, and is the author of Weapons of Math Destruction.

Cathy says she was always a math nerd. She loves the beauty of mathematics, and says it is almost an art – the cleanliness of it. One of her favorite things is that math is the same no matter what country you go to. She also had had an interest in the business world, which led her from academia to work as a hedge fund quantitative analyst.

Big Data is both a technical and marketing term. The technical term depends on the technology you are using. Big data used to mean that it was more data than you could fit on your computer – now it means more that you can perform in a simple way – that it needs to be put it into another form before it can be used.

The marketing term, ‘big data’ is misleading. However, it represents the belief that you can collect data for one thing but then the same data can be used for another purpose. “It is a technology that allows us to collect seemly innocuous data and use it for another purpose.”

One profession in which O’Neil has at looked at the use of big data and algorithms in detail – and discusses in her book – is teaching and their evaluations. She says there were teacher evaluation algorithms originally designed to eliminate the achievement gap between ‘rich kids and poor kids’. Eventually, a new system was devised entitled, ‘value added teacher model’.

The idea of this new system intended to offset the previous way of looking at assessing teachers - where they solely looked at the teacher’s students’ final test scores.

The ‘value added score’ system holds teachers accountable for the difference between students’ final score and what they were expected to achieve/receive.

O’Neil says that this method ‘sounds good’ and seems to ‘make sense’. However, with only 25 (or so) students in one teacher’s classroom, there is not enough data. Additionally, both the expected and actual scores have a lot of uncertainty around each of them. So this final number ‘ends up not much better than a random number’. With that, there is not enough credible data to base important decisions such as terminating a teacher’s job.

One of O’Neil’s main points in today’s discussion is that every algorithm is subjective. Whether it is used to evaluate teachers, hire or fire employees in a financial organization - people should know that they have the right to ask the algorithm explained to them. The 14th Amendment provides them ‘due process’ to ask why they are terminated, not promoted, etc. - other than just alluding to a algorithm result.

What you will learn in this episode:

  • What is ‘weaponized math’?
  • How is the internet building a new kind of ‘class’?
  • What are the 2 definitions of ‘big data’?
  • The potential bias found in the use of algorithms in teacher evaluations, hiring practices, firing

Sparks: Five Trends Reshaping the Future of Work: Why Challenging Convention is the New Normal

What can a world chess champion teach us about the future of work? More than you think. Just like Magnus Carlsen challenged convention to become the greatest player in history, leaders today need to rethink everything about how we work, lead, and build organizations. This episode explores why challenging convention is no longer optional. We unpack the five trends reshaping work—new employee behaviors, exponential technology growth, a millennial-majority workforce, mobility, and globalization—and why clinging to outdated assumptions is a losing strategy. From redefining what it means to be a manager or employee to understanding the Josh’s of the world who thrive without traditional paths, we learn that the future belongs to leaders who aren’t afraid to question norms, rethink structure, and design organizations people actually want to be part of.   ________________ Start your day with the world’s top leaders by joining thousands of others at Great Leadership on Substack.

How to Use The Six Sources of Influence to Create Behavior Change That Lasts

How to Use The Six Sources of Influence to Create Behavior Change That Lasts

Great ideas often die, not because they’re wrong, but because no one knows how to influence others to act on them. In leading today’s complex organizations, it’s not enough to be right. The real challenge for leaders is getting people to change behavior, and stay changed. In this episode, we sit down with Joseph Grenny, co-author of Crucial Conversations and one of the world’s leading experts on influence and behavior change, to unpack the science and strategy behind lasting behavior change using his powerful Six Sources of Influence framework. We explore the difference between persuasion and true influence, why most change efforts fail, and how even well-intentioned leaders often rely on the wrong tools—like incentives or policies—when they should be focusing on motivation, social systems, and structural design. Joseph shares real-world stories, including how The Other Side Academy transformed the lives of former felons without a single failed drug test in over a decade. We also look at corporate examples, such as how to pitch ideas internally, how to harness peer pressure the right way, diagnose resistance to change, and why influence always begins with empathy, not authority. ________________ Start your day with the world’s top leaders by joining thousands of others at Great Leadership on Substack.

Sparks: How Recognition Shows Your Real Culture Beyond Engagement Scores

In this episode of Leadership Spark, KeyAnna Schmiedl, Chief Human Experience Officer at Workhuman, challenges leaders to stop relying on outdated engagement scores and start looking at what really drives culture: recognition.

The Shocking Truth Behind Empty Shelves and a Broken Global Trade System

The Shocking Truth Behind Empty Shelves and a Broken Global Trade System

We’ve built a world where products appear with a click and groceries restock like clockwork...until they don’t. When the pandemic hit, it wasn’t just shelves that went empty, it was our illusions of a stable, efficient global supply chain that collapsed. And it wasn’t a freak accident, it was decades in the making. In this episode, we sit down with Peter Goodman, Global Economic Correspondent for The New York Times and bestselling author of How the World Ran Out of Everything: Inside the Global Supply Chain. Peter brings a deep, behind-the-scenes look at how global trade works, and what happens when it doesn’t. We unpack the hidden risks and questionable logic behind decades of offshoring, our blind devotion to just-in-time inventory, and a relentless pursuit of shareholder maximization at the expense of resilience. Peter covers the untold story behind what went wrong during the pandemic and why it could happen again, why we became too dependent on China, and how consulting firms and shareholder obsession made things worse. We also dive into how AI could help (or hurt) global logistics, why nationalistic trade policies could hurt your business more than you think, and what the future of trade and sourcing looks like in a more unstable world. ________________ This episode is sponsored by Workhuman: AI without purpose doesn’t serve people.

Sparks: Recognition Matters: How Small Gestures Can Mean a Lot for Company Culture

What does real employee recognition look like, and why do so many leaders still get it wrong? In today’s Leadership Spark, I explore how one emotional moment completely changed a leader’s definition of what it means to acknowledge and value your people.

How Kettering University Prepares Students for AI, Tech & Jobs of Tomorrow

How Kettering University Prepares Students for AI, Tech & Jobs of Tomorrow

Is college still worth it? As tuition rises and dropout rates soar, the big question everyone’s asking is: how do we prepare young people for a future we can’t predict? In this episode, Dr. Robert McMahan, President of Kettering University, unpacks the evolving crisis in higher education and what it truly means to prepare students for the future. He sheds light on the rise of “adulting” classes as a symptom of a larger issue: students entering college without essential life skills. Dr. Robert gives us a peek into Kettering University's integrated experiential model, where students rotate between 12 weeks in class and 12 weeks in cooperative placement roles at real companies—not internships, but embedded work. We also look into why traditional four-year universities are struggling, facing declining public trust, overcapacity, and the looming demographic cliff, and how new learning models and market disruptions are forcing a much-needed reimagining of higher education. Dr. McMahan emphasizes that future-proofing students isn’t about teaching them fixed skills like coding, but cultivating habits of mind: critical thinking, adaptability, resilience, and the ability to solve complex problems. ________________ This episode is sponsored by Workhuman: Don't you hate how every HR company out there says they are powered by AI?
