Social media and communication
Wellbeing, relationships, misinformation and the way people talk to each other now.
This is the part of the subject where competent researchers most openly disagree. Correlational analyses of very large samples find effects close to zero; quasi-experiments and deactivation trials find small but real ones. Both are reported here without resolution, because the disagreement is the honest state of the field rather than a gap to paper over. For a workplace-oriented example of technology measurement in practice, see this guide.
The literature genuinely disagrees with itself here, and the disagreement is the finding.
| Article | Findings | Strong / mixed / weak |
|---|---|---|
| How everyday communication changed Traditional calls and texts are in measured decline while app messaging and calling carry several times the volume, but the effects on comprehension are barely measured. |

| Who actually sees and shares false content Fake news exposure and sharing are concentrated in a tiny minority of users and amount to a fraction of a per cent of what people consume. |

| Relationships that start online Meeting online has become the single most common route into a US couple, and no outcome study finds those relationships are worse or shorter. |

| Whether an online presence changes hiring There is no controlled evidence that personal branding works, and the measurable effects of an online presence on callbacks run through discrimination. |

| What social media does to people The best correlational studies bound the effect near zero and the best experiments find a small negative one, and the disagreement between them is unresolved. |

How everyday communication changed
UK voice minutes are falling and text messages are collapsing, while app traffic dwarfs both. What that does to understanding is much less well measured.

Who actually sees and shares false content
Exposure to fake news is concentrated in about 1% of users, sharing in about 0.1%, and it makes up 0.15% of the average American media diet.

Relationships that start online
Online is now the most common way US couples meet, and couples who meet that way split up at the same rate as everyone else. The two headline numbers differ.

Whether an online presence changes hiring
No controlled study shows personal branding improves hiring outcomes. What field experiments do find is discrimination on identity cues visible in profiles.

What social media does to people
Large correlational studies find almost nothing; randomised deactivation trials find a small negative effect. Both are strong. The field has not settled.
