# Action Selection

We’ve seen different cognitive actions that a model can take to answer a question, including:

1. Just answer the question directly.
2. Run a debate if it’s a pro/con question.
3. Search a long text for relevant information.
4. Decompose the question into subquestions.
5. Run a web search using Google.
6. Run a computation in Python.
7. Write out reasoning steps.

In this chapter, we’ll use a model to choose which of these to run. We’ll look at two cases:

1. [One-shot action selection](https://primer.ought.org/chapters/action-selection/one-shot-action-selection): Just choose a single action.
2. [Iterative action selection](https://primer.ought.org/chapters/action-selection/iterative-action-selection): Given the results of actions so far, choose the next action.
