摘要
Natural direct and indirect effects are defined through cross-world interventional counterfactuals. We propose an alternative construction based on backtracking counterfactuals. Rather than intervening on the treatment or mediator and change the structural equations, we use a backtracking conditional distribution to construct an alternative exogenous state satisfying a desired treatment-mediator constraint and then evaluate the unchanged structural equations on that state. This yields the backtracking direct and indirect effects, and also the backtracking total effect. Likewise, we adapt the population intervention effects.
