Practical ethical decision-making is a framework for making decisions that best approximate the recommendations of idealized decision-making in real-world situations.

Idealized decision theory assumes that we have taken into account all possible consequences of our actions. But we often forget to take into account the indirect effects of our actions or the actions of others when assessing these outcomes.

We are also not perfectly rational: sometimes it can be difficult to weigh up all of the evidence available to us, and we need a more practical guide to how to assess different kinds of evidence.

Even if we have views about the correct theory of value, we need practical advice about how we should measure and compare the value of the different interventions available to us.

Finally, it is often natural to think in terms of problems, interventions, and focus areas, rather than thinking purely in terms of actions, states, and outcomes.

General frameworks for practical decision-making can therefore help us to assess the effectiveness of different interventions and focus areas in real-world situations.
