Glaze

Glaze had not always seen through her own icing.

When she was small, she believed whatever coat a choice was wearing. A cereal box said "80% sugar-free," and she thought it was healthy, without noticing that meant one fifth of it was sugar. A ride at the fair said "only a 5% chance of getting wet," and she happily climbed on, but a different ride said "1 in 20 riders gets soaked" and she refused, though the two numbers were exactly the same.

One afternoon her best friend pointed that out, laughing, and Glaze felt silly and hot-faced. She'd been so sure she was choosing by the facts.

Solon, the mentor, found her later, scraping icing off a spoon a bit harder than she needed to. "You weren't silly," Solon said. "You were human. Scientists gave people the very same rescue plan described two ways, '200 saved' or '400 lost,' and people chose differently depending only on the words." Solon handed her a clean spoon. "The fix is simple and it takes one breath. Before you choose, peel off the wording and say the plain numbers. Both ways round."

So Glaze practised peeling. Eighty percent sugar-free: twenty percent sugar. A five percent chance: one in twenty. Ninety loved it: ten didn't. Every time, she said it both ways, and every time the shiny coat came off and she could see the plain cake underneath.

She came to BiasForge because it was a place where people learned to see tricks like this one.

"What do you bring?" Solon asked.

"Icing," Glaze said. "I ice the same facts two ways, so visitors can feel the pull of the wording, and then learn to peel it off."

Whim, the quick, gut-feeling part of everyone, sniffed the cakes. "The 'loved it' one smells better," Whim said.

"It's the same cake," said Glaze, laughing. "That's exactly the point."

The hedgehog came back later with a card from the lab's shelf. It showed two summer camps. Camp Sunny: "Most campers say they'd come back!" Camp Pine: "4 out of 10 campers say they wouldn't come back."

"Sunny sounds way better," the hedgehog said, and then stopped. "Wait."

"Peel it," said Glaze.

The hedgehog thought hard. "If four out of ten wouldn't come back at Pine, then six out of ten would. And 'most' at Sunny could mean six out of ten too." She looked up. "I can't tell which is better. They might be the same."

"So what would you want to know?" Glaze asked.

"The real numbers for both," said the hedgehog. "Said the same way."

Muse, the careful, slow-down part of everyone's thinking, gave an approving nod. That was the move.
