On TV, in Parliament, in headlines.
Bob is "The Precautionary Guardian".
He sees himself as the last line of defense between ordinary people and dangerous technologies. Pesticides, GMOs, chemicals - in his mind, they are lurking threats.
He has built a career out of warning people about them.
I met Bob one gray morning in London. We drunk coffee, and had a conversation I would never forget 🧵👇1/
Rain streaked down the glass walls of the Bundestag’s café. The place smelled of espresso and wet coats. I was early, nervous but steady.
I knew what Bob represented: a worldview that had shaped European politics for decades.
He arrived right on time. Tall, polite, almost scholarly in his composure. He shook my hand firmly, smiled warmly, and yet his eyes gave away his purpose. He wasn’t here for small talk.
We sat, coffee cups steaming between us. His black, mine with milk.
And then, without hesitation, the debate began. 2/
“Simon,” Bob said, voice calm but sharp,
“glyphosate is dangerous. The WHO itself called it a probable carcinogen. Why should we risk cancer just to save some diesel fuel? Better to plough the fields. Better safe than sorry.”
He said it with such certainty that I could imagine hundreds nodding along.
I leaned in.
“Bob, every regulator in Europe and North America - EFSA, BfR, EPA, Health Canada - looked at the same evidence.
They all concluded the same thing: glyphosate poses no cancer risk at real-world exposure.”
I paused, then shifted the ground.
“But when glyphosate is banned, farmers plough more. That means:
20% more CO₂ from tractors
More soil erosion
Fewer earthworms
So tell me, Bob: is that really precaution?”
He stirred his coffee slowly.
“Cancer is personal, Simon. Soil erosion is abstract. People worry about their health more than worms.”
I smiled.
“Not if you’re a farmer watching your topsoil blow away.” 3/
Spend 20 years studying a subject.
Go online. Get told you’re wrong by an electric screwdriver salesman…
🧵 Let’s talk about the collapse of trust in expertise: 1/
This isn’t just about bruised egos.
It’s about what happens when we flatten every voice to the same level…and ignore the difference between evidence and opinion. 2/
We used to trust people who dedicated their lives to understanding complex topics.
