I have started to do this in real life where I get a sudden feeling of urgency (that I am needed somewhere or have to check for messages from my team or respond to the CEO's text). As soon as I catch it, I press both feet down firmly on the ground for just a few seconds. It immediately calms me down. Stop and smell the roses, as they say.
I find myself doing this a couple dozen times a day.
You said the magic keyword: "curiosity", when it comes to computers and tech at least. Something that I find severely lacking among - for lack of a better term - Gen Z.
It's the difference between hackers and users. You probably don't rebuild your car's transmission and don't build your own long-distance radio, but there are people that do it for fun. However, there was a time when both drivers and operators consisted mainly of people that hacked on cars and radios. Some of the hackers were involuntary hackers and gladly became users when cars became appliances.
The same applies to PCs. Gen X and older Millennials had to become hackers just to get the sound working in their newest game, so if you saw a guy on IRC you knew he was a fellow hacker. Now everyone is online, including people who would simply not use a PC back in the 80's or 90's. They can afford to treat their personal computing devices the way I treat my personal commuting device: fuel goes into this hole, I need to consult the manual to open the boot to top up window washing fluid, the rest I happily delegate to a professional. But the hackers are still there: grease monkeys, DXers, hackers proper.
One favorite recollection of the Twitter API usage was this guy who hooked up a pressure sensor to a Twitter account, and placed the sensor under his newly married friend's bed - and the thing would tweet when the couple got in bed. [0]

Not sure if you are joking, but with features like "Instant Articles", Facebook has every reason to keep people on facebook.com rather than sending them to external websites.
When you are locked down in a walled garden that allows messaging (within the garden) and every other service is blocked, people will simply believe that walled garden is all there is.
