Payphone research brief · For employers
What workplace phone-distraction research actually says.
The evidence supports reducing active phone interaction and notifications during attention-critical work. It does not support a universal number for hours lost, dollars wasted, or productivity recovered in every workplace.
The practical takeaway
Do not buy a universal productivity promise. Test whether a bounded, rewarded period of phone-free work improves the operational result your team already trusts.
Active interaction, notifications, and task switching can compete with focused work.
The claim that merely having a phone nearby reliably reduces everyone's cognition.
A site-level pilot that connects verified Focus sessions to objective outcomes and employee experience.
What the studies show
Useful evidence—with the caveats left in.
These findings support the mechanism behind focused work. None of them is a Payphone outcome study, and none justifies a universal productivity percentage.
Randomized workplace experiment
Routine calling activity increased in a phone-restricted condition
A four-hour experiment with 121 telephone interviewers found roughly 13% more call attempts per minute under the strongest condition, which combined a phone restriction with trust-based messaging. Completed interviews did not improve as reliably, so the result supports increased activity—not a universal 13% productivity claim.

Disabling notifications improved performance and reduced strain
In a field experiment with 247 participants, disabling communication-app notifications for one workday benefited parts of performance and strain. The effects varied with factors such as fear of missing out and workplace telepressure.

A nearby phone alone is not the strongest evidence
Across 166 effects from 53 samples, the overall cognitive effect of a smartphone’s mere presence was essentially zero. A small negative effect appeared in one working-memory subset. The more defensible business concern is active interaction and interruption—not phone proximity by itself.

Some tasks carry much higher distraction stakes
FMCSA reports that commercial drivers who text are 23.2 times more likely to experience a safety-critical event. This is not a general workplace crash multiplier; it is task-specific evidence that active phone interaction can become especially consequential in safety-sensitive environments.

Start where focus can be measured cleanly.
Contact centers, inside sales, appointment setting, recruiting, and routine back-office teams are practical early use cases. Their work often includes phone-light windows and high-frequency outcomes such as attempts, completions, handle time, accuracy, or throughput.
Good pilot fit
- A defined phone-light work window
- 25 or more eligible employees
- A trusted operational KPI
- A quality or safety guardrail
- Voluntary participation and a modest reward
Safety-sensitive environments may offer meaningful upside, but require more policy, emergency-access, and workflow review before launch.
A claims boundary buyers can trust
What Payphone will—and will not—claim.
We can responsibly say
- Active phone use and alerts can interrupt attention.
- Specific controlled studies found benefits from reducing interruption.
- Payphone verifies bounded Focus participation and rewards it.
We will not assume
- Every employee loses the same number of minutes.
- Every Focus minute converts directly into productive output.
- A third-party result is a Payphone customer outcome.
A credible way to evaluate Payphone
Measure the intervention, not a made-up national average.
A 15-day self-serve trial can validate onboarding and participation. A decision-grade operational pilot needs enough baseline and intervention time to separate signal from ordinary variation.
- 01
Choose one measurable work window
Start with a 60–180 minute period when personal phones are not essential and the team already tracks a trusted operational result.
- 02
Record a clean baseline
Measure the existing workflow for two to four weeks. Account for role, shift, staffing, workload, seasonality, and quality—not only output volume.
- 03
Run a bounded Focus intervention
Invite employees to use Payphone during the selected window for six to eight weeks. Track adoption and verified quiet time as mechanisms, not as proof of productivity by themselves.
- 04
Decide from business outcomes
Compare the pre-agreed operational KPI alongside quality or safety and employee-experience guardrails. Expand only when the combined result is positive.
Privacy-safe measurement
Verify Focus. Do not inspect the phone.
Employers can evaluate eligible time, verified quiet time, completed sessions, rewards, and a pre-agreed business KPI. Payphone does not show employers apps used, messages, browsing, screen contents, precise location, or off-shift activity.
Focus is all-or-nothing. An employee can end it whenever necessary; ending the session stops rewards and resets momentum rather than pausing the ramp in place.
