What is Read Receipts?
Once the sender can see you have read their message, not replying starts to feel rude. This pushes you to respond on the app's schedule rather than your own.
Where it comes from
BlackBerry Messenger (2005)
How it hooks you
Exploits reciprocity guilt: visible proof that you saw a message turns an ordinary delay into something you feel you must explain.
How to resist it
Turn off read receipts in every messaging app you use.
