In Judea Pearl's "Book of Why" he talks about what he calls the Ladder of Causation, which is essentially a hierarchy comprised of different levels of causal reasoning.

What does correlation vs causation mean lowest is concerned with patterns of association in observed data e. What I'm not understanding is how rungs two and three differ. If we ask a counterfactual question, are we not simply asking a question about intervening so as to negate some aspect of the observed world? There is no contradiction between the factual world and the action of interest in the interventional level. But now imagine the following scenario. You know Joe, a lifetime smoker who has lung cancer, and you wonder: what if Joe had not smoked for thirty years, would he be healthy today?

In this case we are dealing with the same person, in the same time, imagining a scenario where action and outcome are in direct contradiction with known facts. Thus, the main difference of interventions and counterfactuals is that, whereas in interventions you are asking what will happen on average if you perform an action, in counterfactuals you are asking what would have happened had you taken a different course of action in a specific situation, given that you have information about what actually happened.

Note that, since you already know what happened in the actual world, you need to update your information about the past in light of the evidence you have observed. These two types of queries are what does correlation vs causation mean distinct because they require different levels of information to be answered counterfactuals need more information to be answered and even more elaborate language to be articulated!.

With the information needed to answer Rung 3 questions you can answer Rung 2 questions, but not the other way around. More precisely, you cannot answer counterfactual questions with just interventional information. Examples where the clash of interventions and counterfactuals happens were already given here in CV, see this post and this post. However, for the sake of completeness, I will include an example here as well. The example below can be found phylogeny used in a sentence Causality, section 1.

The result of the experiment tells you that the average causal effect of the intervention is zero. But now let us ask the following question: what percentage of those patients who died under treatment would have recovered had they not taken the treatment? This question cannot be answered just with the interventional data you have. The proof is simple: I can create two different causal models that will have the same interventional distributions, yet different counterfactual distributions.

The two are provided below:. You can think of factors that explain treatment heterogeneity, for instance. Note that, in the first model, no one is affected by the treatment, thus the percentage of those patients who died under treatment that would have recovered had they not taken the treatment is zero. However, in the second model, every patient is affected by the treatment, and we have a mixture of two populations in which the average causal effect turns what does correlation vs causation mean to be zero.

Thus, there's a clear distinction of rung 2 and rung 3. As the example shows, you can't answer counterfactual questions with just information and assumptions about interventions. This is made clear with the three steps for computing a counterfactual:. This will what food can you buy with ebt card be possible to compute without some functional information about the causal model, or without some information about latent variables.

Here is the answer Judea Pearl gave on twitter :. Readers ask: Why is intervention Rung-2 different from counterfactual Rung-3? Doesn't intervening negate some aspects of the observed world? Interventions change but do not contradict the observed world, because the world before and after what does correlation vs causation mean intervention entails time-distinct variables. In contrast, "Had I been dead" contradicts known facts. For a recent discussion, see this discussion.

Remark: Both Harvard's causalinference group and Rubin's potential outcome framework do not distinguish Rung-2 from Rung This, I believe, is a culturally rooted resistance that will be rectified in the future. It stems from the origin of both frameworks in the "as if randomized" metaphor, as opposed to the physical "listening" metaphor of Bookofwhy. Counterfactual questions are also questions about intervening. But the difference is that the noise terms which may include unobserved confounders are not resampled but have to be identical as they were in the observation.

Carlos Cinelli Carlos Cinelli A couple of follow-ups: 1 You say " With Rung 3 information you can answer Rung 2 questions, but not the other way around ". But in your smoking example, I don't understand how knowing whether Joe would be healthy if he had never smoked answers the question 'Would he be healthy if he quit tomorrow after 30 years of smoking'.

They seem like distinct questions, so I think I'm missing something. But you described this as a randomized experiment - so isn't this a case of bad randomization? With proper randomization, I don't see how you get two such different outcomes unless I'm missing something basic. By information we mean the partial specification of the model needed to answer counterfactual queries in general, not the answer to a specific query.

And yes, it convinces me how counterfactual and intervention are different. I do have some disagreement on what you said last -- you can't compute without functional info -- do you mean that we can't use causal graph model without What does correlation vs causation mean to compute counterfactual statement? For further formalization of this, you may want to check causalai. Show 1 more comment. Benjamin Crouzier. Christian Christian 11 1 1 bronze badge. Sign up or log in Sign up using Google.
