Mention the Trabant, and most people picture a smoky, sputtering plastic car, the butt of endless jokes about East German engineering. Nicknames like “A Disgusting Belch of Communism” or “a spark plug with a roof” cemented its reputation as a symbol of socialist-era stagnation. But this common image barely scratches the surface of a far more complex and fascinating story. It’s a tale of remarkable innovation born from desperation, of surprising durability that became a fatal flaw, and of a vehicle that drove its way through the Iron Curtain and into the history books. ...

When you hear the term “plastic car” today, you might picture something cheap, flimsy, or disposable. But in the resource-scarce landscape of post-war East Germany, “plastic” wasn’t a pejorative—it was the future. Engineers were pioneering a revolutionary material that was not only tough and lightweight but was also derived from some of the most unassuming industrial and agricultural byproducts. The car was the AWZ P70, and its body was crafted from a remarkable composite called Duroplast. This wasn’t the flimsy plastic of modern stereotypes; it was a testament to ingenuity in an era of scarcity. Here are five surprising truths about this forgotten wonder material that challenge everything we think we know about “plastic” cars. ...

Audit Your Instincts: The Playbook for Engineering Unbiased Decisions The Hidden Trap in Your Brain Every day, you make countless decisions—from what to eat for lunch to which job offer to accept. For the most part, your brain uses a phenomenal shortcut system, which Nobel laureate Daniel Kahneman called System 1. This system is fast, intuitive, and runs on gut feeling. It’s efficient, but it’s also the source of predictable errors known as cognitive biases. ...

The Economics of Less: What Shrinkflation Reveals About Price, Perception, and Power The Silent Reduction A consumer reaches for their familiar carton of ice cream, the price exactly where they left it, yet something feels subtly wrong—the carton shape is slimmer, the quantity reduced. This common, seemingly minor disappointment, repeated across countless grocery aisles and product categories, is the frontline experience of a pervasive economic maneuver known as shrinkflation. This term describes the practice where manufacturers or retailers reduce the size or quantity of a product while keeping its price unchanged. The result is an effective increase in the per-unit price for consumers without an explicit price hike. This strategy is often employed as an indirect response to rising production costs, allowing firms to recover expenses without triggering the sharp consumer backlash that might result from overt price increases. ...

Have you ever walked across a bridge or through an underpass and felt a sudden, inexplicable sense of either safety or profound unease? Perhaps one structure felt welcoming and calm, while a geometrically identical structure nearby made you quicken your pace. That visceral reaction is not random; it is a direct response to a complex web of subtle design cues present in the environment. Urban designers refer to this instantaneous assessment as “perceived safety,” which involves the subjective feelings and assessments users make about their security within a given environment. For decades, this subjective feeling was treated as secondary to “actual safety,” which relied strictly on measurable, objective data points like accident and collision reports. ...

You’re Playing a Game Right Now From maneuvering in traffic and negotiating a salary to navigating social relationships, you are constantly playing games. This isn’t to say life is trivial, but that we are all participants in a complex web of interactions where the outcome depends on the choices of others. Game theory is the formal study of these interactions, but its findings often run contrary to our intuition. It reveals that the logical underpinnings of our behavior can lead to strange, surprising, and sometimes unsettling outcomes. ...

The Endowment Effect of Digital Ownership: 5 Surprising Truths About Why We Overvalue What We Own Introduction: The Invisible Force Behind Your Possessions Have you ever tried to sell a used car, a piece of furniture, or even an old smartphone, only to feel that every offer you receive is offensively low? Or maybe you’ve felt an irrational attachment to a digital item in a video game that has no real-world value. This feeling isn’t just about sentimentality; it’s the result of a powerful cognitive bias called the “endowment effect”—an invisible force that convinces us our stuff is special, just because it’s ours. ...

The Secret Language of Luxury: 4 Surprising Truths About the Status Game Have you ever noticed how a certain watch, handbag, or car can change the way a person is perceived? We often think of luxury goods as simple badges of wealth, straightforward ways to say, “I’ve made it.” But what if that’s only the most basic, and often misleading, part of the story? The truth is, displaying luxury is less like putting up a billboard and more like speaking a complex, secret language—a high-stakes game of communication with unspoken rules and hidden meanings. ...

Imagine you’re shopping online and see two offers: a high-quality pen for $1 plus $2.99 shipping, or a slightly lower-quality pen for $3.99 with “free” shipping. Many of us would instinctively choose the “free” shipping option, even though it’s the same price for a worse product. This isn’t just about saving money; it’s a powerful psychological quirk at play. This phenomenon is known as the zero-price effect. It describes our tendency to react with disproportionate excitement to something that costs nothing, often leading us to make choices that aren’t entirely rational. This post will explore the most surprising takeaways about why the word “free” has such a powerful hold on our decision-making. ...

Pay Less, Feel Worse? The Counterintuitive Psychology of Your Monthly Subscriptions Take a quick look at your email inbox or bank statement. Chances are, it’s a testament to the modern subscription economy, with recurring charges for everything from streaming services and software to meal kits and groceries. We sign up for these services in the name of convenience, access, and simplicity, offloading routine purchases to an automated system. Yet, despite the clear benefits, many of us feel a sense of unease. There’s the low-grade anxiety of “subscription fatigue” or the surprising sting that comes from watching those small, regular payments leave our account. This creates a paradox: we subscribe to make life easier, but the very mechanism of recurring payments can create its own unique psychological burden. Why do we have such a deep psychological ambivalence toward our subscriptions? ...
