Why do divination and dog hunting show that they can't be retrieved?

Divination has no scientific basis, but a probabilistic event. It is difficult to get the dog back without a positioning device. If you're lucky, you'll meet good people to take you in. It is more useful and practical to print a dog-seeking notice than to take money for divination.

Divination is aimed at a certain thing, and you can only do it when you want to do it, depending on the result, good or bad. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
