In 2015, Michal Kosinski and his colleagues at Stanford published a study in the Proceedings of the National Academy of Sciences that should have changed how everyone thought about the internet. It mostly didn't.
The study was simple. They took a group of Facebook users and had their close friends, family members, and coworkers rate the users' personalities on a validated personality test. Then they had a machine learning model do the same thing, based on nothing but the user's Facebook likes.
Here's what they found. With 10 likes, the model was more accurate at predicting your personality than your work colleagues were. With 70 likes, it beat your friends. With 150 likes, it beat your family members. With 300 likes, it beat your spouse.
Three hundred likes. Most people generate that many in a bad month.
What this actually means
The finding wasn't that computers are magic. The finding was that human personality is much less private than we thought, and much more visible in casual behavior than we imagined. The things you like, the pages you follow, the videos you watch to completion — these aren't neutral choices. They're a personality test you're taking constantly, without knowing.
And now everyone can see the answers.
That was 2015. Every platform now runs models orders of magnitude more sophisticated. They don't just know your personality. They know your mood at 9 PM on Sunday. They know when you're about to make a purchase before you do. They know which words in a headline will make you click and which will make you scroll past.
The itch
Here's what this means for how it feels to be a person now.
You know that reaching feeling? The one where you pick up your phone to check something and end up 40 minutes deep in a rabbit hole you didn't choose? The one where an ad shows up for something you were literally just thinking about? The one where the exact video that catches your eye is the one you had no idea you wanted to watch?
That's not you. Or it is you, but a version of you that's been mapped in more detail than you've ever mapped yourself, and then sold to whoever was willing to pay to reach that version.
The itch you're reaching for was placed there by someone who studied that pattern.
What to do about it
I don't think the answer is to unplug. I've tried that. It doesn't hold. The world runs on these systems and stepping outside them means stepping outside a lot of things you actually want to be inside.
What I think the answer is: notice.
Every time you reach for the phone, name the reaching. Say it out loud if you have to. "I am reaching for my phone." That's it. You don't have to stop. You just have to notice.
Because the entire industrial complex behind these systems is built on you not noticing. On the reaching being automatic. On the scroll being reflexive. The moment you notice, you have a choice. The moment you have a choice, you are back in charge of your own attention, at least for that one moment.
That's not enough. But it's the beginning of enough.
And it's the only thing I've found that actually works.
