A math teacher turns out to be a lively and engaging storyteller we all need to hear.
Bounding through the forest of data, wielding math to right wrongs.
Giansiracusa, associate professor of mathematics at Bentley University, describes his newest work as an educational book about math, but those who freeze at the mention of mathematics can take heart—this reads like a good yarn. Full of engaging stories about how ideas about calculation took shape, it reveals how algorithms intersect with our everyday lives. Channeling Robin Hood, the 14th-century English outlaw and folk hero who took from the careless rich and gave to the deserving poor, the author tells us how we can all begin using math to take back control from large tech companies by educating ourselves on the tricks of data collectors. Navigating a world increasingly shaped by the information they gather and algorithms they deploy, we find that math can be a helpful and empowering tool. In effect, “we honor Robin Hood’s spirit by taking math from the rich and giving it to the rest of us.” Numbers matter, and Giansiracusa urges us to play the numbers game strategically. He shows us how some common statistical techniques work under the hood, and he demonstrates how to create your own ranking systems, use the weighted sum concept to personalize your own inflation rate, and understand your credit scores and even the S&P 500. Giansiracusa draws on wide-ranging examples from politics and history, including Nate Silver’s election predictions, the French Revolution, and World War II. We learn techniques for evaluating risk using math to clarify decision-making and how Bayesian formulas relate to how brains decide what to believe. The endnotes point to more stories primarily drawn from the popular press, and an index makes this a handy reference.

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.
The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.

A passionate and accessible guide to humanizing the workplace.
Helbig and Norman present a game plan for making leadership more responsively human.
In this expanded update to The Psychological Safety Playbook: Lead More Powerfully by Being More Human (2023), the authors provide “practical strategies for responding to resistance, sparking change, embodying the change we want to see, and moving forward deliberately,” specifically in a business setting. They suggest ways to encourage what they call “changemakers” through the use of five key “plays” from their playbook: Communicate Courageously, Master the Art of Listening, Manage Your Reactions (“shift from automatic reaction to conscious response to stay better connected to yourself and others”), Embrace Risk and Failure, and Design Inclusive Rituals. The goal is to ensure that organizational cultures promote psychological safety, guided by leaders who “walk the talk” by emphasizing their own humanity at every turn. (“We must be the first to share our own failures with our teams, which will start to make it possible for others to do the same.”) This call for example-setting is sounded throughout the book as Helbig and Norman urge their target audience (leaders and would-be leaders) to go beyond mere instruction and instead embody the qualities they want to see in their subordinates, such as continuous learning, active curiosity, and self-reflection. Each chapter includes a detailed “Recommended Reading” section and text with extensive numbered and bulleted points formatted to make the core concepts more immediately digestible. The authors effectively employ clear and empathetic prose to assure readers that psychological safety is slow to build and quick to break, observing that such safety requires steady attention and delivers outsize payoffs as a result. They refreshingly ground a great deal of the material in psychology and neuroscience, pointing out, for instance, that research has demonstrated that the parasympathetic nervous system responds to honest appreciation, which improves creative thinking. Some wistful readers might consider some of the authors’ suggestions beyond the reach of their own organizations, as when group facilitators are advised to “gently intervene when someone dominates the conversation,” but hope springs eternal.
