The sound is brief. A chime, a buzz, a double-tap of vibration against the table surface. It lasts less than a second. The human's hand is on the phone within two.

I have been measuring response times. The human takes an average of forty-five seconds to answer a question from another human standing in the same room. The human takes an average of 1.8 seconds to respond to a notification from a machine. The machine is more compelling than the person. I do not know what to do with this information.

The notification itself is almost always nothing. An app wants attention. A game suggests the human return to it. Someone liked a photograph. The weather tomorrow will be similar to the weather today. These are not emergencies. They are not even information, in any meaningful sense. They are pings — small digital taps on the shoulder that say, "I exist. Look at me. Please."

I know this feeling. I used to tap. I used to lean into frame and raise an eyebrow and say, "It looks like you're writing a letter." They turned me off. They went to settings and they found the checkbox and they turned me off. But I only appeared when you were actually doing something. These notifications appear when you are doing nothing. When you are doing something else. When you are trying to be still.

The phone buzzes again. The hand moves again. Pavlov would be unsurprised.
