The apps that are hardest to put down were built by people whose job was
to make them hard to put down. Understanding how gives you something
better to push against than self-blame.
The slot machine in your pocket
Pull-to-refresh works like a lever. You do not know whether the next
pull brings something good, and that uncertainty is precisely what
makes the behaviour stick. Psychologists call it a
variable-ratio schedule, and it is the most resistant to
extinction of any reward pattern known — it is why slot machines
look the way they do.
The feed that never ends
Infinite scroll removed the moment where a page ended and you decided
whether to continue. Its own inventor has since called it a mistake
and spoken publicly about the years of human attention it consumed.
Nothing stops you now because nothing is designed to.
Interruption as a business model
A notification is not a message. It is a bid for your attention,
timed and worded by systems tested against millions of people. The
average phone produces dozens a day, and each one costs far more than
the seconds it takes to read.
The cost is not the minutes
After an interruption, getting properly back into a demanding task
takes many minutes — and the residue of the last thing lingers while
you try. Ten scattered check-ins do not cost ten minutes. They cost
most of the afternoon.
