The research behind the Living Meter

Where the hours go, under 18

These two pies are the Common Sense Census of media use by tweens and teens, surveyed in 2021 and published in 2022. The ages are 8 to 18. Children under 8 have a different day, and they are not in the chart. The numbers are the average across every young person in the group, including the ones who did not do that thing at all that day. The time can overlap, because a person can watch and scroll in the same hour, so the slices are the census categories, not a claim that the day has no double-counting.

A movie at a theater was about four minutes a day in 2019. By 2021 so few had gone that the census stopped counting it. A movie watched at home is inside Shows or Online video. The survey does not split films from series, so this page will not invent that split.

A newer census, released in October 2026, still finds about eight hours a day for a typical teen and about five for a typical tween, and says short-form video such as TikTok and YouTube Shorts is now close to two hours of a teen's day. That report has not published a full table by category, so the pies stay with the last complete count.

What is being measured

Eight questions, each scored from 0 to 10: work, the household, piety, courage, ordered liberty, temperance, truth, and what is left for the people after you. The Living Meter is their average, times ten. The questions are old. The arithmetic is plain so two houses can compare a story without pretending the number is a lab result.

People copy what they see rewarded

Albert Bandura, social learning

Bandura showed that people learn conduct by watching it, especially when the conduct is rewarded and the model is easy to imitate. A screen is a model. A story that makes cruelty charming, or fidelity ridiculous, is a rehearsal whether or not the house meant to hold one. The Living Meter asks, before the rehearsal starts, whether the story rewards what a house means to keep.

Heavy viewing changes what feels normal

George Gerbner, cultivation

Gerbner's cultivation research found that people who watch a great deal of television come to see the world as more like the world on the screen. The effects in the published studies are often modest, and later scholars have argued over how large they are. The finding the desk uses is the modest one: a diet, repeated, teaches a sense of the normal. A weekly count is a way to see the diet instead of absorbing it.

Talking about the story changes what a child keeps

Parental mediation, including Amy Nathanson

Researchers distinguish three household habits. Restrictive mediation is the rule about what may be on. Active mediation is talk about what was on. Co-viewing is sitting in the room together. Nathanson and others found that active mediation, the talk, is the habit most clearly tied to a child taking less of the harmful lesson. The Sunday swap is built for that: one title left, one title kept, and a reason the house can say out loud.

The same hour becomes a habit

Wendy Wood and David Neal

Habit research finds that a behavior tied to a stable cue, such as the hour after supper, becomes automatic. The cue fires and the hand reaches for the same shelf. A measure that arrives at that hour gives the house a chance to interrupt the reach. The Living Meter is placed before the play button for that reason. It is not a willpower lecture after the episode has already started.

What the screen-time fights do not settle

Studies of hours-of-screen and harm do not speak with one voice. Some find links with sleep, attention, and mood. Others find small effects, or effects that depend on what was watched and whether a parent was in the room. The Living Meter does not take a side in the hour-count war. It scores the story. Two hours of a worthy film and two hours of a cruel one are not the same evening, and a meter that only counts minutes would treat them as the same.

What we will not say

• We do not say the meter diagnoses a person, a child, or a disorder.
• We do not say a single evening determines a character.
• We do not invent a study, a journal, or a percent to make the page sound finished.
• We do say a repeated diet teaches, that talk changes what a child keeps, and that a house can choose the diet on purpose.
