Who should decide when experts disagree with voters?
Expert knowledge can inform a public choice without settling its values.
A town must choose between two transport plans. Engineers prefer one for reliability; residents prefer the other for neighborhood access. Calling the residents uninformed would miss a real priority. Treating technical analysis as irrelevant would miss another. The disagreement concerns both predicted outcomes and the values used to compare them.
Define the expert question
An expert can help assess whether a bridge can carry a load. Deciding which neighborhood should receive a bridge involves distribution, priorities, and public accountability. Expertise remains useful, but its authority should be tied to the question it can actually answer.
Make assumptions visible
A forecast may rely on assumptions about demand, maintenance, or behavior. Publishing those assumptions gives people something specific to challenge. Public scrutiny should ask whether the model fits the decision, rather than treating uncertainty as proof that every estimate is worthless.
Keep responsibility attached
If elected officials delegate a decision, they should explain the scope of that delegation and how it can be reviewed. If they reject expert advice, they should explain their reasoning and accept responsibility for the choice. Neither a technical report nor a popular vote should become an excuse to avoid explaining consequences.
