# Why can't I move cards anywhere I want?

Automatic layout saves you important time and promotes focus on the content. Consistency (i.e. left-to-right arrangement) and good aesthetics (i.e. minimal tangling) ensure maps are fast to read and always presentation ready.

# Scores

## How are scores calculated?

Scores range from 0-100 and are designed to help you understand the value of outcomes and power of actions (a.k.a. cost-benefit). That way, you can understand both how they rank globally and easily compare your options.

Calculations are performed in two steps:

- Onebrief calculates the cumulative value of each card based on what might result from it, given its linkage, card ratings, and link ratings. For that, it applies a probabilistic model (i.e. Bayesian network).
- Then, outcomes and actions, are separately scored (think of it as "grading on the curve"). Outcomes are scored based on their intrinsic value plus the cumulative value of their effects. Actions are scored based on the cumulative value of their effects divided by their required effort/cost.

## How is relative value calculated?

Relative value used for filtering, is calculated using the same idea of cumulative value explained in the previous item.

In addition:

- For the card you have selected, Onebrief determines which actions and outcomes might lead to or result from it.
- Then, it ranks them based on their cumulative value weighted by how likely they are to lead to or result from the card you have selected.

## What does each rating level mean?

Rating scales are fuzzy by design. In other words, what each level means really doesn't matter in most cases. What matters most is how cards are rated relative to each other.
