It's Not Just You: The Reality of Adult Friendship in 2026

KEYPOINTS

• 01

  Social health is a third pillar alongside physical and mental health

  Social scientist Kasley Killam, who has studied connection for about 15 years and holds a master's from the Harvard T.H. Chan School of Public Health, says decades of research across thousands of studies point the same way: connection predicts a longer, healthier life. She notes that the World Health Organization recently said social health matters as much as physical and mental health, and she wants it to become as mainstream a topic as mental health is now.

• 02

  Loneliness is common, so it's nothing to be ashamed of

  She cites a study in which one in six Americans said they were isolated or lonely most or all of the time. Her first message to lonely listeners is that it's a widespread condition, not a personal failing, and that it can be changed with small, specific habits.

• 03

  We spend dramatically less time with friends than we used to

  Per Killam, young people today spend nearly 1,000 fewer hours a year with friends than 20 years ago. Mel works out that's about 25 forty-hour work weeks. She adds that 67% of Americans never take part in any club or group, and 72% see the people they care about only two, one or zero times a month.

• 04

  Disconnection is a physical stressor

  Killam explains that feeling isolated registers in the body as stress, releasing cortisol, which can increase inflammation and over time make you more susceptible to illness. Connection does the opposite. This is her framing of the research, not individual medical advice.

• 05

  'Protecting your peace' can tip into isolation

  Healthy relationships are sometimes difficult, and human connection is messy. If you cut out everyone who causes any friction, you can end up with no one. She suggests reframing 'protecting your peace' so it allows for normal friction.

• 06

  Most cancelled plans are excuses, not needs

  Mel polled her audience and 73% admitted cancelling on friends or colleagues because they'd rather stay home alone. They sorted listeners' reasons into 'excuse' and 'need' jars, and the excuse jar filled up. Some reasons are both: 'I never get asked questions back' is an excuse to skip, but it also signals a real need for new friends. Social anxiety is valid and normal, but if you always use it as a reason to stay in, you won't meet anyone.

• 07

  People like you more than you think

  In one study, strangers chatted and then rated how much they liked their partner and how much they thought their partner liked them. People consistently underestimated how much they were liked, while outside observers judged it correctly. In another set of studies, people underestimated how much a friend would appreciate a quick check-in. Killam treats this as reason enough to push past insecurity and reach out.

• 08

  Connection doesn't have to take much time to matter

  77% of Americans work more than 40 hours a week. Her fix is 'go for connection first': when a meeting ends five minutes early or you're waiting in line, text a friend instead of scrolling. She says research shows a short text, a 10-minute phone call or five minutes of expressing gratitude can reduce loneliness.

• 09

  We've optimized for convenience over connection

  Nobody looks up anymore, so organic meetings are rarer. The reliable way to make new friends is to join a local group you care about, so you see the same people regularly, then take action when you click with someone.

  Curiosity is the most underrated way to deepen a friendship

  Ask questions and genuinely listen rather than waiting for your turn to talk. Opening up more yourself also helps.
