Judea Pearl: 'truncation by death' solutions follow from universal calculus, not tricks
yudapearl · x · 2026-11-14
Causal inference pioneer Judea Pearl pushed back against critics, arguing that problems like 'truncation by death' don't require clever statistical tricks — their solutions follow from a universal calculus derived from the mathematical representation of the problems themselves.
The spat began when a critic questioned Pearl's approach, citing the standard repair that assumes treatment doesn't change patient survival. Pearl framed this as statisticians projecting their own shortcomings onto causal inference.
