Omega-3 supplementation → Employment status
A rise in Omega-3 supplementation does not identify a change in Employment status.
Fish-oil buyers are not a random sample of the labor force.
Observational · High confidence
The association disappears when you account for other factors, like socioeconomic status or healthy-user bias.
Mechanism
Omega-3 use clusters with education, income, and other preventive behaviors. Any raw association with unemployment is the bias, not the oil.
Caveats
This edge is about economic outcomes, not triglycerides. Do not export the verdict to cardiology.
Effect
qualitative. Same healthy-user structure as multivitamins.
