Basic worries with matching have also been lifted by Judea Pearl, who has argued that concealed bias could basically improve for the reason that matching on observed variables may unleash bias on account of dormant unobserved confounders. Likewise, Pearl has argued that bias reduction can only be assured (asymptotically) by modelling the qualitative causal associations amongst procedure, final result, noticed and unobserved covariates.
