A book of true stories

UNINTENDED

The Strange Consequences of Good Ideas

The first time I heard the story about the cobras in Delhi, I did what I always do when something genuinely surprises me. I told it to someone else. Then I told it again. And then I started looking for more stories like it.

I have loved stories with unexpected endings ever since I first read Guy de Maupassant. Sudden reversals. Quiet ironies. The moment a narrative turns on you and you realize you had it backwards the entire time. Mark Twain once said that truth is stranger than fiction, because fiction has to make sense. He was right. The real world doesn't owe us a satisfying arc. It just does what it does, and sometimes what it does is absurd.

This book is a collection of true stories where things didn't go as planned. Some are famous. Some are obscure. All of them share the same basic shape: someone saw a problem, designed a solution, and watched the solution make everything worse. Or stranger. Or both.

I didn't set out to prove a grand theory. But as the stories piled up, patterns started to emerge, and I couldn't ignore them.

The first pattern is about brute force. Changing a complex system by wrestling it into submission almost always backfires. Whether it's nature, infrastructure, or culture, the more interconnected the parts, the more likely you are to trigger something nobody predicted. If you must intervene, think about how to undo it. Leave room for the system to adapt.

The second is about shortcuts. People take them. If there's an easier way to get a reward, someone will find it. Systems that ignore this tend to fail. Worse, they sometimes fail quietly, in ways nobody notices until the damage is done.

The third is about time horizons. Most of what we build is aimed at solving short-term problems. That isn't a criticism. It's just how the world works. But without mechanisms to reward long-term thinking, those short-term wins have a habit of turning into long-term disasters.

There are more takeaways, and I'm sure you will find your own. These stories are just a starting point. If nothing else, I hope they give you a few great anecdotes to share at a dinner, a meeting, or the next time conversation starts to run dry.

And if one of them surprises you the way the best stories do, then I'll consider this project a success.
