# Deduction

Many questions require multiple steps of inference before they can be answered. The simplest approach is to do this kind of reasoning within a single language model call—“chain of thought”, and that’s all we’re covering in the Primer right now:

* [Chain of Thought](https://primer.ought.org/chapters/deduction/chain-of-thought): Let’s think step by step.

However, there are more compositional ways of approaching this, including the one outlined in the paper [Selection-Inference](https://arxiv.org/abs/2205.09712), and the reader (you) is encouraged to implement them.
