The problem with contemporary communication is not only that we receive too many messages. It is that each message arrives with the expectation that it can interrupt whatever else we are doing.
A 2026 study in Mobile Media & Communication examined 774 adults and found that more frequent email use and more chat notifications were associated with a greater sense of task load and hurry. The study describes not necessarily more work, but more activities kept open in the mind at once.
Research in Frontiers in Psychology reaches a similar conclusion: parallel messages and alerts move attention away from the original task and make it harder to recover the same flow and understanding. The authors connect this to time pressure and lost cognitive continuity.
