The scene
You unlock a phone to check one thing. The home screen is a constellation of red. None of the numbers is an emergency. Each is an unfinished sentence the mind now holds.
Named evidence
Stothart, Mitchum and Yehnert (2015) found that cellular notifications disrupted performance on an attention-demanding task even when participants did not interact with the device. Ward and colleagues (2017) found that mere presence of the phone can tax available capacity. Together they specify a cost that is not identical with “using the phone too much.”
Effects vary by job and whether alerts are truly time-critical. Treat “notifications ruin focus” as directionally supported in the lab and still in need of workplace-specific trials.
For living and designing
Batch. Turn counts into binaries, or into nothing. If a product needs a badge to stay relevant, the relationship is already fragile. Organisations: an always-on alert culture is not seriousness. It is a refusal to decide what is urgent.
