Benevolent deceptions can hide uncertainty (like when Netflix automatically loads default recommendations if it doesn’t have the bandwidth to serve personalized ones), mask system hiccups to smooth out a user’s experience (like when a progress bar grows at a consistent rate, even if the process it’s visualizing is stuttering), or help people get used to a new form of technology (like the artificial static that Skype plays during quiet moments in a conversation to convince users the call hasn’t been dropped).
