A visible phone measurably reduces the quality of a face-to-face conversation, though the effects are smaller than the headlines suggest. In a restaurant field experiment with 304 participants, diners whose phones were on the table reported more distraction and less enjoyment than those who put them away.
Chapter three of Open Doors is about phone etiquette, and it is the chapter people are most likely to roll their eyes at before they read it. So let me stay close to the evidence and away from the sermon.
What has actually been measured
Researchers sent families and friends to a restaurant meal. One group kept phones on the table, the other put them away. The phone group reported more distraction and less enjoyment of the meal. The authors are notably honest about the size of it: the effects were, in their words, relatively small.
A second study by the same team followed 123 people through 1,244 real face-to-face conversations as they happened. Phone use predicted more distraction, less enjoyment, and less feeling of connection, consistently and modestly.
A separate experiment on being phubbed, which is being snubbed in favour of a phone, found much larger effects on how the other person rated the conversation and the relationship.
Those last figures are from Pew Research, surveying 3,217 adults, and they contain the whole problem in three numbers. Nearly everyone does it. Most people think it damages the conversation. Almost nobody thinks it is acceptable in a meeting.
We have collectively agreed this is rude and collectively kept doing it.
Where I will not overclaim
An early and much-cited study found that the mere presence of a phone reduced closeness and trust between two strangers. A later pre-registered replication with 356 participants failed to reproduce that particular effect.
I am telling you that because it is true, and because the version of this argument that survives replication is quieter than the one in circulation. The phone in your pocket is probably not poisoning your relationships. The phone you glance at mid-sentence is doing something smaller and more specific: it is telling the person in front of you where they rank.
It does not stay at work either. Across two surveys of 453 adults, 46% reported being phubbed by their own partner and 23% said it had caused conflict between them. A habit built in meetings is the same habit at a kitchen table.
The professional version
Everything above is about friends and dinner tables. Translate it into a professional room and the stakes change, because in that room somebody is deciding about you.
Energy is the third letter of the TEEE Score, and it is the only dimension you never experience directly. You cannot feel your own presence. You only ever see its consequences, months later, in who gets asked back.
- Phone out of sight in any conversation that matters. Not face down. Away. Face down still signals that it is waiting.
- Name it if you must break the rule. "I am expecting a call about my mother, I apologise in advance" costs one sentence and removes the insult entirely.
- Notice the reflex. The reach for a pocket during a pause in conversation is a habit, not a decision, and habits are visible to everyone but their owner.
The effects in the research are small. The cost of acting on them is smaller still, which is an unusually good trade and one of the few in professional life available to anyone, immediately, at no expense.

Frequently asked
What is phubbing?
Phone snubbing: attending to a phone instead of the person you are with. Experimental work finds it lowers how the other person rates both the conversation and the relationship.
Does a phone face down on the table still matter?
Face down still signals that the phone is waiting. In the restaurant field experiment, the meaningful comparison was phones present versus phones put away entirely.
Is the research on this solid?
Partly. The restaurant and experience-sampling studies replicate a small consistent effect, and the authors say plainly the effects are small. An earlier finding that the mere presence of a phone reduces trust failed a pre-registered replication.
