"95% of all messages are. "Can I call you?" It's hard to separate cause and effect though, 95% of my messages are "Can I call you?", sometimes repeated 3-4 times, simply because the system often fails to reliably transmit anything longer without messages being lost, arriving out of order, etc. It is clearly hard to observe the users scientifically when the interface affects their behaviour.
