Comparison of predictions: What the notebook outputs: the event occurs between 24 Oct 2051 and 17 Sep 2059, Ben Pace should pay SDM $87. Otherwise, SDM should pay Ben Pace $13. What this is actually doing: None No comments

We made a colab notebook that lets you generate a bet from two people's Elicit distributions. You can edit the notebook to generate your bet (the changes won't be saved). Here's an example of a suggested bet between Ben Pace and SDM on AI timelines:

## Comparison of predictions:

## What the notebook outputs:

**If the event occurs between 24 Oct 2051 and 17 Sep 2059, Ben Pace should pay SDM $87. Otherwise, SDM should pay Ben Pace $13. **

**Disagreement: **You disagree most between 24 Oct 2051 and 17 Sep 2059.

**Probabilities: **Ben Pace thinks the probability the event occurs in this range is 8%, while SDM thinks it's 18%.

**Odds: **You should make a bet with 87:13 odds.

**Expected Value: **Given your beliefs, you each win $5 in expectation

## What this is actually doing:

- We search across the question range to find the interval (with a width of 10% of the total range) where your probabilities differ the most, including the probabilities outside of the bounds
- We determine odds that create equal and positive expected value for each person using the method outlined in this blog post
