These examples run the current decision engine. They keep the donor’s personal help value fixed at 6.46 USD, with the same answers, need scenario and delivery assumption. Only local prices and the stated constraints change.
Local fraud rate: unknown
The slider is a hypothetical risk assumption. It is not measured Japanese or Uzbek fraud prevalence. The starting midpoint of 50% does not mean the countries have equal real risk.
For this illustration, the donor reports having checked the need (p=1). Delivery is the unvalidated q=85% assumption. The four recorded answers produce a 2.625 multiplier on the same reference exercise; personal value is converted between currencies rather than re-estimated from each meal’s price.

Why the country can change the answer
A payment must fit your limit and provide useful help. With the same personal value, a higher local price can make the payment lose its modeled benefit. An agreed partial contribution can restore a useful option. A verified contradiction stops that particular payment in either country.
Country labels alone do not change honesty. Two countries with identical relevant inputs should receive the same answer. Different prices, checked facts, calibrated local evidence when available, and your constraints are reasons for different answers.
