Private Self
who you are when no one is watching.
Inner life, emotion, and self-understanding — the domain traditional psychology and medicine have long studied.
We study digital life as public health.
The Third Self Project is a research and education initiative exploring how online identity, community, and culture shape human wellbeing — and what public health must do to meet people where they actually live.
The Third Self explained
We use the Three Self framework to describe how identity operates across private life, social expectation, and digital environments. Each layer shapes health differently — and public health has historically studied only the first two.
Social Self
who the world expects you to become.
Roles, norms, and performance — how family, culture, and institutions shape who we are allowed to be.
Third Self
the identity built inside digital environments.
Avatars, anonymous accounts, parasocial bonds, and platform-native community — a new layer of selfhood that public health is only beginning to measure.
Why digital public health
The internet did not create new human needs. It reorganized them — loneliness, belonging, identity, and access to care now flow through systems designed for engagement, not wellbeing.
-
Platforms shape behavior
Algorithms, design patterns, and incentive structures influence attention, sleep, relationships, and self-concept at population scale.
-
Community moved online
Support, harm, and identity formation now happen in digital spaces as often as physical ones — often with fewer guardrails.
-
Data leaves the clinic
Health signals appear in search history, social posts, and app usage long before they appear in medical records.
-
Equity gaps widen
Digital access, literacy, and safety are unevenly distributed — digital public health must center those most affected.
Research, education, community
Three practices, one goal — to treat digital life with the same rigor, care, and community accountability we bring to physical health.
-
Research
We conduct and synthesize studies on digital identity, online community, masculinity, loneliness, and the intersection of platform design with mental health — publishing findings for practitioners and the public.

Education
Through the Journal, resources, and public programming, we translate complex research into accessible language — for clinicians, educators, parents, and anyone navigating life online.

Community
We build spaces for dialogue, peer support, and participatory research — because the people who live digital life every day are essential co-investigators, not just study subjects.

A public health that includes the internet.
We believe the next era of public health will be written in both code and clinic.
Our long-term vision is a field where digital environments are studied with the same seriousness as air quality or infectious disease — where policymakers, clinicians, and technologists share a common evidence base about how online life affects real bodies and real communities.
We are building toward open research infrastructure, cross-disciplinary partnerships, and public literacy about digital wellbeing — not as a wellness trend, but as a structural commitment to health equity in a networked world.
This work takes time. We publish carefully, partner generously, and hold ourselves accountable to the communities whose stories we document.
