Think of it like moving a husky dog from Siberia to the Sahara. Nothing has changed with the dog, but it's not functioning quite as well after the move.

The classic examples are things like going to a library where everyone else is silent and studying, finding a job that suits your temperament, like accounting for the sensitive type and ambulance driving for the sensation-seeking type. Create a social contract for exercise meet-ups, and downgrade to a dumb phone to overcome doom scrolling. Having the router block all Internet traffic after 10 o’clock. And so on.

Moving from one place to another is immensely helpful for some. Changing friends, and even starting or stopping medication, counts as environmental changes in this instance, since it's part of the arena on which the personality plays itself out.

Just make sure to stay away from all this “nudge” people. They never have anything helpful to actually contribute to in this.
