# Prediction markets for public opinion

Prediction markets require users to translate beliefs into data.

* “We’re in a bull market” must be expressed as “Bitcoin will be worth over \[$price] on \[date] according to \[exchange].”

This means they can *only address beliefs that can be easily derived from data.*

But many of our most important beliefs, cannot:

* **“Taxation is theft.”**
* **“God exists.”**
* **“Epstein didn’t kill himself.”**

What data could possibly confirm or refute these? It’s not possible.

But using Ideamarket, you could create a prediction market based on *what the public will believe 1 year from now.* Throughout the year, both sides will be incentivized to produce the best possible evidence for their case, *and* to understand the arguments on both sides, *and* to judge honestly.

Ideamarket could make prediction markets exponentially more useful by enabling them to address subjective, un-resolvable, *human* questions: **prediction markets for public opinion.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ideamarket.io/use-cases/prediction-markets-for-public-opinion.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
