Good Thinking: A Call to Rational Action

Good Thinking by David Robert Grimes is a beacon for the rational mind—a reminder that thinking well isn't just a skill; it's a necessity in today's world. Grimes writes with clarity, humor, and an unwavering commitment to evidence-based reasoning, providing readers with an essential toolkit to navigate the often murky waters of modern information. From the opening story of Stanislav Petrov, the Soviet officer who prevented a nuclear catastrophe by trusting his own judgment over faulty data, Grimes sets the tone for what follows: a sharp exploration of flawed thinking and how to rise above it.

Part One: Without Reason - Formal Fallacies

The book is divided into six compelling sections, each of which builds on the last to create a cohesive guide to better reasoning. Part One kicks off with a deep dive into formal fallacies—common errors in logical structure that undermine arguments. Grimes isn't content to let these fallacies exist in theory; he brings them to life with real-world examples, demonstrating how they shape public discourse and our daily decisions. I appreciate how he draws clear distinctions between ad hominem attacks (attacking the person rather than the argument), false dilemmas, and the like, making it easy for readers to identify and avoid them. This approach is reminiscent of the clarity I found in Good Thinking, which provides practical ways to confront everyday misinformation.

Part Two: Spotting and Debunking Dubious Rhetoric

In Part Two, Grimes delves into dubious rhetoric and the subtle ways language can manipulate us. This is where the book becomes especially practical, offering a framework to spot rhetorical tricks that often pass unnoticed—tricks that sway opinions without making a single logical point. The real strength here is how Grimes connects these abstract concepts to the very real tactics used in advertising, politics, and even our personal lives. I can't help but see the parallels with Ben Ramalingam's Upshift (review), where similarly practical frameworks for transforming pressure into creativity are explored.

Part Three: The Struggle Between Reason and Belief

The struggle between reason and belief is tackled in Part Three. Grimes examines why we often cling to irrational beliefs, exploring confirmation bias and motivated reasoning. He doesn't shy away from the uncomfortable truth: it's not enough to be intelligent if we aren't willing to question our own beliefs. He challenges readers to take a hard look at themselves, to become not just skeptics of the world but skeptics of their own minds. This self-examination is reminiscent of the themes in Shirzad Chamine’s Positive Intelligence, where confronting our own mental saboteurs is necessary for true growth.

Part Four: How Numbers Can Mislead Us

Grimes shifts gears in Part Four to talk about numbers and the ways they can mislead us. This section is a reminder that statistics, when used poorly, are as dangerous as misleading rhetoric. He provides examples of correlation vs. causation, cherry-picking data, and misleading averages, all of which I found immensely relevant in an age where data is weaponized to push narratives. His clear explanations make these concepts accessible, even for those without a background in statistics.

Part Five: How Media Indulges Bad Thinking

In Part Five, Grimes critiques the media's role in perpetuating poor thinking. He takes aim at sensationalism, false balance, and the incentives that drive media outlets to prioritize clicks over truth. This resonates with what I’ve observed—particularly in tech and AI reporting—where nuanced issues are often simplified or distorted for the sake of a headline. The message here aligns well with my experience at The Thinking Spot, where discerning what’s meaningful and what’s sensationalized is an ongoing effort, especially in today’s polarized landscape.

Part Six: What Science Is and What It Is Not

Finally, Part Six is a reflection on science—what it is and what it is not. Grimes underscores that science is not a collection of immutable facts but a method of inquiry—a continuous process of questioning, testing, and refining. He draws a clear line between genuine scientific skepticism and denialism, encouraging readers to understand science as a way to seek truth, rather than a static body of knowledge. This perspective reminds me of the lessons in Moshe Bar's exploration of mind wandering, where scientific curiosity and openness lead to some of our most profound discoveries.

Throughout the book, Grimes references the work of other notable scientists—Daniel Kahneman, Amos Tversky, Carl Sagan. These references enrich the narrative, situating his arguments within a broader intellectual tradition. His admiration for these figures shines through, lending weight to his calls for critical thinking.

Good Thinking is more than a book—it’s an invitation to engage with the world more thoughtfully. Grimes writes with the kind of immediacy that makes the reader feel that each lesson is directly applicable, whether it’s about analyzing news, assessing a scientific claim, or even navigating an office discussion. This is why I found it so powerful. It’s not theoretical; it's deeply practical, something that resonates with my day-to-day experiences and my drive to better understand the world around me.

If you are looking for a way to cut through the noise and see the world more clearly, this book is for you. As Richard Dawkins puts it, "If our leaders were forced to read this book, the world would be a safer place."
