Most of this platform is data-driven by design. Wearables, biomarkers, algorithms — the system knows a lot about me. But it doesn't know everything, and it can't know what I need before the data catches up.
Challenges are my sandbox. No hypothesis required, no controlled variables. Sometimes it's something I read, sometimes it's something Brittany and I brainstorm together, sometimes it's just a gut feeling that a particular week needs a particular thing. Date nights. Acts of service. A week without complaining. These things matter — they make the journey worth taking — and they didn't have anywhere else to live in the system.
The data will catch up eventually. Challenges are how I stay ahead of it.
Experiments are science. They have a falsifiable hypothesis, a controlled protocol, a minimum duration, and published data. They test whether something works. They belong in the Lab.
Challenges are action. No hypothesis required. Pick a protocol, commit to the duration, see what happens. They test whether you can do it. They belong in the Arena.
Challenges run 7–30 days. Complete one, earn a badge, and if the data gets interesting — it graduates to a formal experiment. Sources include board recommendations, data signals, and whatever Brittany and I think of on a Sunday.
