You’re preparing for an appointment.
You realize you may be late. Then you realize you can text that you’re on your way. You think: keeping them waiting isn’t so bad knowing you had a problem and will be a few minutes late.
Whew! That was close. You almost faced results for being late but got out of it.
When you’re texting you’ll be late, it feels like a minor get-out-of-jail-free card.
But consider the behavior it motivates.
The big picture is that
texting enables everyone to be late as long as they text on the way, which results in a culture of lateness—more people late more often.
Then again, my model that everyone gets fifteen minutes works pretty well.
