What happens when technology knows more about us than we do?

A computer now can detect our slightest facial microexpressions

and be able to tell the difference between a real smile and a fake one.

Technology has become incredibly intelligent

and already knows a lot about our internal states.

we already are sharing parts of our inner lives

because a lot of us like to keep what's going on inside

We want to have agency over what we share and what we don't.

But I'm here to tell you that I think that's a thing of the past.

And while that might sound scary, it's not necessarily a bad thing.

I've spent a lot of time studying the circuits in the brain

that create the unique perceptual realities that we each have.

with the capabilities of current technology

to create new technology that does make us better,

we have to be OK losing some of our agency.

and we get to see into their internal experiences.

We get this upfront look at the mechanistic interaction

between how they respond to the world around them

and the state of their biological systems.

This is where evolutionary pressures like eating, mating

drive deterministic behavioral responses to information in the world.

into their internal states and their biological experiences.

Now, stay with me for a moment -- I'm a violinist, not a singer.

But the spider's already given me a critical review.

Poppy Crum: It turns out, some spiders tune their webs like violins

And likely, the harmonics of my voice as it went higher

recreated either the predatory call of an echolocating bat or a bird,

The spider's responding to its external world

in a way that we get to see and know what's happening to its internal world.

Biology is controlling the spider's response;

it's wearing its internal state on its sleeve.

We like to think we have cognitive control over what people see, know and understand

our emotions, our insecurities, our bluffs, our trials and tribulations --

Your eye responds to how hard your brain is working.

The response you're about to see is driven entirely by mental effort

and has nothing to do with changes in lighting.

I promise, your eyes are doing the same thing as the subject in our lab,

Try and understand them and keep watching the eye in front of you.

one should drop out, and it should get really easy.

You're going to see the change in effort in the diameter of the pupil.

(Single voice) Intelligent technology depends on personal data.

your autonomic nervous system drives your pupil to dilate.

the cognitive effort to understand the talkers

I could have put the two voices in different spatial locations,

We might think we have more agency over the reveal of our internal state

Today's technology is starting to make it really easy

to see the signals and tells that give us away.

The amalgamation of sensors paired with machine learning

on us, around us and in our environments,

is a lot more than cameras and microphones tracking our external actions.
