Blindsight

“Vision’s mostly a lie anyway,” he continued. “We don’t really see anything except a few hi-res degrees where the eye focuses. Everything else is just peripheral blur, just — light and motion. Motion draws the focus. And your eyes jiggle all the time, did you know that, Keeton? Saccades, they’re called. Blurs the image, the movement’s way too fast for the brain to integrate so your eye just — shuts down between pauses. It only grabs these isolated freeze-frames, but your brain edits out the blanks and stitches an — an illusion of continuity into your head.”

He turned to face me. “And you know what’s really amazing? If something only moves during the gaps, your brain just — ignores it. It’s invisible.”

I glanced at his workspace. The usual splitscreen glowed to one side — realtime images of the scramblers in their pens — but Histology, ten thousand times larger than life, took center stage. The paradoxical neural architecture of Stretch Clench glistened on the main window, flensed and labeled and overlaid by circuit diagrams a dozen layers thick. A dense, annotated forest of alien trunks and brambles. It looked a little like Rorschach itself.

I couldn’t parse any of it.

“Are you listening, Keeton? Do you know what I’m saying?”

“You’ve figured out why I couldn’t — you’re saying these things can somehow tell when our eyes are offline, and…”

I didn’t finish. It just didn’t seem possible.

Cunningham shook his head. Something that sounded disturbingly like a giggle escaped his mouth. “I’m saying these things can see your nerves firing from across the room, and integrate that into a crypsis strategy, and then send motor commands to act on that strategy, and then send other commands to stop the motion before your eyes come back online. All in the time it would take a mammalian nerve impulse to make it halfway from your shoulder to your elbow. These things are fast, Keeton. Way faster than we could have guessed even from that high-speed whisper line they were using. They’re bloody superconductors.”

It took a conscious effort to keep from frowning. “Is that even possible?”

“Every nerve impulse generates an electromagnetic field. That makes it detectable.”

“But Rorschach’s EM fields are so — I mean, reading the firing of a single optic nerve through all that interference—”

“It’s not interference. The fields are part of them, remember? That’s probably how they do it.”

“So they couldn’t do that here.”

“You’re not listening. The trap you set wouldn’t have caught anything like that, not unless it wanted to be caught. We didn’t grab specimens at all. We grabbed spies.”

Stretch and Clench floated in splitscreen before us, arms swaying like undulating backbones. Cryptic patterns played slowly across their cuticles.

“Supposing it’s just — instinct,” I suggested. “Flounders hide against their background pretty well, but they don’t think about it.”

“Where are they going to get that instinct from, Keeton? How is it going to evolve? Saccades are an accidental glitch in mammalian vision. Where would scramblers have encountered them before now?” Cunningham shook his head. “That thing, that thing Amanda’s robot fried — it developed that strategy on its own, on the spot. It improvised.”

The word intelligent barely encompassed that kind of improvisation. But there was something else in Cunningham’s face, some deeper distress nested inside what he’d already told me.

“What?” I asked.

“It was stupid,” he said. “The things these creatures can do, it was just dumb.”

“How do you mean?”

“Well it didn’t work, did it? Couldn’t keep it up in front of more than one or two of us.”

Because people’s eyes don’t flicker in synch, I realized. Too many witnesses stripped it of cover.

“ — many other things it could have done,” Cunningham was saying. “They could’ve induced Anton’s or, or an agnosia: then we could have tripped over a whole herd of scramblers and it wouldn’t even register in our conscious minds. Agnosias happen by accident, for God’s sake. If you’ve got the senses and reflexes to hide between someone’s saccades, why stop there? Why not do something that really works?”

“Why do you think?” I asked, reflexively nondirective.

“I think that first one was — you know it was a juvenile, right? Maybe it was just inexperienced. Maybe it was stupid, and it made a bad decision. I think we’re dealing with a species so far beyond us that even their retarded children can rewire our brains on the fly, and I can’t tell you how fucking scared that should make you.”

I could see it in his topology. I could hear it in his voice. His nerveless face remained as calm as a corpse.

“We should just kill them now,” he said.

“Well, if they’re spies, they can’t have learned much. They’ve been in those cages the whole time, except—” for the way up. They’d been right next to us the whole trip back…
