What we believe
Most of what wears people down is not understanding how humans actually work, not a lack of effort.
The Human Frequency teaches how humans actually work: the nervous system, the biases we all carry, and the family and social systems we live inside. We teach it so people can close the gaps that separate them from themselves, their kids, and each other. We don't publish motivation. We publish operating systems.
Here's what we believe. Under each one is the evidence. Where the science is strong, we show you. Where it's still a bet, we say so.
Connection is a health factor, not a luxury.
People with strong social ties live longer and get sick less. The effect is large enough that researchers now rank isolation alongside the health risks your doctor already tracks. That's why everyone is welcome here. Not as a slogan. As the point.
Evidence: across 148 studies and 308,849 people, stronger social relationships went with a 50 percent higher likelihood of survival over the follow-up, an effect the authors call comparable with established mortality risk factors. Holt-Lunstad, Smith and Layton (2010), PLoS Medicine. DOI. In a quarantine study, people with more kinds of social ties caught fewer colds after the same virus exposure. Cohen et al. (1997), JAMA. DOI.
A sense of purpose changes your odds.
In a study of nearly 7,000 older adults, the people with the lowest sense of purpose were about two and a half times more likely to die over the follow-up than those with the highest. We treat purpose as an input to a working life, not a poster on a wall.
Evidence: 6,985 adults over 50 in the US Health and Retirement Study, followed from 2006 to 2010; hazard ratio 2.43 for the lowest purpose group against the highest. An association in a cohort, not a trial. Alimujiang et al. (2019), JAMA Network Open. DOI.
You can't fight hatred with hatred. And you don't have to.
When people feel attacked, they dig in. But in randomized field trials, a single conversation of about ten minutes that trades stories instead of arguments has lowered prejudice for months. Calm, curious, and non-judgmental is not the soft option. It is one of the better-studied ways to change a mind.
Evidence: 56 canvassers held roughly ten-minute doorstep conversations built on taking another person's perspective with 501 voters; the drop in prejudice held at three months. Broockman and Kalla (2016), Science. DOI. In three later trials with 6,869 voters, arguments alone did nothing, and conversations that added a non-judgmental exchange of personal stories cut prejudice for at least four months. Kalla and Broockman (2020), American Political Science Review. DOI.
People make more sense in context.
We're wired to blame character and skip past circumstance. Psychologists named it: the fundamental attribution error. The driver who cut you off, the parent who snapped, the kid who melted down. Read the situation before you read the person. It's usually carrying more weight than you can see.
Evidence: the term comes from Ross (1977), "The intuitive psychologist and his shortcomings", Advances in Experimental Social Psychology. DOI.
Everything is connected, and it shows up in the body.
What happens early, and what happens around us, doesn't stay in the mind. Childhood adversity tracks into adult physical health in a graded, dose-response pattern: the more kinds of adversity, the higher the risk. That's the whole reason we teach systems instead of tips. A tip patches one part. An operating system accounts for how the parts move together.
Evidence: 9,508 adults; the number of adverse childhood exposure categories showed a graded relationship to adult heart disease, cancer, lung disease, fractures and liver disease. Felitti et al. (1998), American Journal of Preventive Medicine. DOI. Confirmed across 37 studies and 253,719 people by Hughes et al. (2017), Lancet Public Health. DOI. What we don't claim: that this survives controls for what families share. In a sibling-comparison study, siblings who faced more adversity were no worse off than their co-siblings on most outcomes. Schwartz, Wright and Valgardson (2019), Child Abuse & Neglect. DOI.
Health is holistic. The clinical word is biopsychosocial.
Body, mind, and circumstance aren't separate departments. They interact, and you can't repair one while ignoring the other two. It's the model the World Health Organization built its classification of functioning, disability and health on, and the backbone of what we call the Human OS.
Evidence: the biopsychosocial model was proposed by Engel (1977), "The need for a new medical model", Science. DOI. The WHO's ICF, endorsed by all member states in 2001, states that it "is based on this model, an integration of medical and social".

Technology should amplify our humanness, not replace it.
We'll be straight about this one. It's a bet, not a settled finding. The research on whether technology helps or harms our connection is genuinely mixed. So we made a choice. We build tools that push you back toward real people and real conversations, and we keep measuring whether they do.
One idea, lived three ways: understanding yourself, understanding your kids, understanding each other.
