# Belief System

> Understanding belief systems and their structure

## Belief System

The Belief System is a set of beliefs that can be attributed to a particular instantiated Self. Beliefs are collected over time through engaging the user in Dialectic, a core capability of Epistemic Me. As beliefs accumulate over time they can then evidenced through an epistemic strategy outlined in Philosophies that have been attached to the Self.

### Types of Beliefs

Beliefs can be expressed in a number of ways:

#### Belief Statement

A Belief Statement might capture a relatively ambiguous concept. A Belief Statement does not have an explicit relationship with an Observation Context, but one can be inferred, optionally.

```python theme={null}
belief_statement, suggestions = epistemic_me.SelfModel.create_belief(
   id="self_001",
   belief_type=epistemic_me.BeliefType.BELIEF_STATEMENT,
   content="Sleeping is good for your health",
)
```

#### Falsifiable Belief

A Falsifiable Belief is a belief that can be tested against observed evidence. For example, "Sleeping 8 hours per night reduces a person's mortality as demonstrated through reduced Heart Rate Variability (HRV)" is a falsifiable belief.

#### Causal Belief

A Causal Belief is a belief that is used to make predictions about the future state of the world. A Causal Belief has an explicit relationship with an Observation Context and it uses both historical evidence and counterfactuals to make a prediction about the future state of the world.
