Organic food is often presented as a healthier, greener or more ethical choice. But when people decide whether to pay extra for organic milk, eggs or vegetables, something else is going on.
Organic food belongs to a curious category that economists call “credence goods”. These are the products whose key qualities can’t be verified even after you’ve bought them. There’s no way that you can tell by looking at, tasting or cooking a food item whether it was genuinely produced to organic standards. Instead, you have to take it on trust.
