What would count as progress
Experimental evidence on how givers allocate with and without comparisons, alongside a clear account of the moral positions.
Why it matters
The Proximity Pull is partly a moral question and partly an information gap. The information gap can be closed, and then we can see what people choose.
Where to start
A scoped survey experiment could test how comparisons across distance affect choices, with its cost and limits stated. The moral side is mapped in the Disagreement Register.
