Loneliness is a signal
John Cacioppo (1951–2018 · University of Chicago) — Loneliness is a signal.
What actually happened?
He started as a psychophysiologist — someone who attaches electrodes and measures what the body does. That is why the loneliness work landed. He did not arrive arguing that people should be kinder; he arrived with blood pressure, inflammatory markers, sleep architecture and cognitive decline, on a subject everyone else was treating as a mood. Once it had numbers attached it stopped being something you could be told to get over.
A signal, not a character defect
Read as a flaw, the first instinct is to say nothing, which seals the only exit. As a signal it carries no shame: it doesn't say something is wrong with you, it says something needs doing.
Vigilance grows it by itself
Lonely people read neutral faces as unfriendlier. The reading makes them withdraw, withdrawal thins the relationship, and the thin relationship confirms the reading. Nobody has to have rejected them for the loop to keep turning.
The effective intervention is the reading, not the opportunity
In the meta-analysis, more chances to socialise, more support and better skills all did little. What came first was correcting the automatic conclusions — which is why doing more events changes nothing.
How do I use it today?
If you feel lonely and embarrassed to say so, separate two things first: am I missing people being present, or people knowing me? Crowds help the first and do nothing for the second. If it's the second, don't add events — catch the automatic sentence ('they must find me tiresome'), write it down, ask what it rests on, and find one chance to test it.

Lines to keep
Hungry, you go find food. This is the same kind of reminder.
Loneliness will read an ordinary face as unfriendly.
For loneliness, changing the reading beats changing the opportunity.
