As evening settled over the Institute, the reading room grew quiet.
Miss Elowen Stray had returned to her notes. Mr Blottisham had wandered off in search of biscuits. Professor Quillibrace remained by the window, gazing thoughtfully at the fading light.
After a moment, Elowen looked up.
“Professor,” she said, “why do people keep making this mistake?”
Quillibrace turned slightly.
“Which mistake?”
“The assumption that answers imply beliefs.”
He considered the question for a moment.
“Because,” he said at last, “for a very long time we have imagined language as a window into the mind.”
“And it isn’t?”
“Oh, sometimes it is,” Quillibrace replied mildly. “But only when there is a mind on the other side of the glass.”
Elowen smiled.
“And a language model?”
Quillibrace gestured lightly toward the laptop on the table.
“That,” he said, “is something rather different.”
“What is it, then?”
“A machine that traces paths through a vast landscape of linguistic possibility.”
Elowen glanced at the political compass chart still lying on the table.
“So when researchers give such a machine an ideology test…”
“…they are not discovering the beliefs of the system,” Quillibrace finished gently.
“They are discovering something else.”
“What?”
Quillibrace smiled faintly.
“The shape of the landscape we ourselves have written.”
Outside, the last light slipped below the horizon.
And for a moment the Institute’s quiet reading room seemed less like a laboratory of artificial intelligence—
—and more like a hall of mirrors.
