We'd rather be honest than impressive.

Our rules

• Every claim links to its source. We link the original paper or report wherever we can. When we link a university or press summary instead, we say so.
• We say how strong it is. Each article carries a label (below).
• Links are not causes. Most research on phones and couples is surveys. We write "linked with", not "causes", unless an experiment shows more.
• We show what didn't hold up. When a famous finding fails to replicate, we say so and cite both.
• We credit ideas to where they started. For example, the "lantern and spotlight" idea comes from psychologist Alison Gopnik.
• No scare statistics, no medical claims. We won't tell you your phone is damaging your health or your marriage.
• No sponsors, no affiliate links, and no data collected from you on this site.
• We review articles twice a year, and each one shows when it was last checked.

Evidence labels

Well established

Large reviews of many studies, or big long-term studies. Unlikely to be overturned.

Promising

Several studies point the same way, but they are smaller, or mostly surveys that show a link rather than a cause.

Mixed

Good studies disagree. We show both sides.

Early or debated

A single study, a finding that did not replicate, or a theory that experts actively dispute.

An idea, not a finding

A useful way of thinking, from a researcher or author, rather than a measured result.
