If the names are removed but the neighborhood's health is still visible

The options

The order shown is not a ranking of preference.

1. Option 1

   Open release of anonymized shared data

   Broadens research opportunities but takes on local stigma and re-identification risk.

2. Option 2

   Restricted use through a resident trust

   Controls uses but narrows the research speed and the participants.

3. Option 3

   Provide environmental samples only

   Reduces individual links but may miss relationships between environment and health.

The situation as it stands

A fictional study jointly analyzing residents' environmental and bodily samples has been proposed. Decision deadline: 50 days until the research participation contract.

Fictional urban health cooperative

1. Premise 1A fictional study jointly analyzing residents' environmental and bodily samples has been proposed.
2. Premise 2Even with personal names removed, health characteristics of a small area can be inferred.
3. Premise 3Researchers explain that the data must be shared widely to compare different interpretations.

Where it holdsSets joint research use of consented data. It does not include individual residents' medical records or non-consented data.

What is still unknown

1. Unknown 1Extent to which data become identifiable when combined with other data
2. Unknown 2Concrete path by which research results return to residents

Signals to decide again

• Define the observation, owner, and confirmation window that will establish "the extent to which data become identifiable when combined with other data," and rejudge when new confirmation changes the tradeoff among the options.
• Define the observation, owner, and confirmation window that will establish "the concrete path by which research results return to residents," and rejudge when new confirmation changes the tradeoff among the options.
