Wellspring and Vet

Wellspring picked up a walking stick, the kind you'd use to hike upstream.

Vet picked up a small careful checklist.

"Puddle," said Wellspring, watching the claim splash from person to person. "Definitely a puddle. Let's go find the spring."

Wellspring went first, because you cannot trust a fact until you've walked it back to where it started.

"Everyone's drinking from the same puddle," Wellspring said, "and nobody's asking where the water came from." So Wellspring started hiking upstream. "Who said the goldfish thing?" Oh, I read it on a poster. "And where did the poster get it?" From a website. "And where did the website get it?" From another website, that got it from a magazine, that got it from... a cartoon?

Up and up Wellspring climbed, past copy after copy after copy — a puddle fed by a stream fed by a trickle — always asking the same stubborn question: but where did they get it? "A copy of a copy of a copy isn't a source," Wellspring said, climbing. "It's an echo. Each time a fact gets passed along, it can get bent, or simplified, or just plain made up somewhere back up the line. I don't want the puddle everyone's splashing in. I want the spring — the first place this water actually came out of the ground. The original. The real study, the real measurement, the person who first found it out."

And when Wellspring finally reached the top — the actual scientists who actually study fish memory — the spring told a very different story than the puddle: goldfish can remember things for months.

But finding the spring wasn't the end — because not every spring is clean, and this was Vet's whole careful job.

"You found the original source," said Vet, "and that's most of the battle. But 'original' doesn't automatically mean 'trustworthy.' Before we drink, I test the water." And Vet ran the checklist — the same handful of honest questions Vet ran on every source, spring or puddle.

Is it current? — Is this recent enough to still be right, or so old it's been overturned? Who's behind it? — Real fish scientists, or someone with no idea, or someone with something to sell? Is it accurate? — Does it show its evidence, or just assert? Does it agree with other good sources? And why was it made? — To inform you honestly, or to scare you, or to sell you fish food?

"This spring passes," Vet said, checking each box on the real study. "Recent. Written by actual researchers. Shows its evidence. Made to inform, not to sell. That's water we can drink." Vet capped the pen. "The checklist isn't about being suspicious of everything. It's about being fair to everything — giving each source the same honest test, so I trust things for real reasons instead of just because they sound right or came first."

So the two of them brought the tested truth back down to the hall — goldfish remember for months, and here's the trustworthy spring it comes from — and, gently, the puddle started to dry up.
