@themattsimpson @sarahdoingthing "Causality is just stuff making stuff happen." circular
@GrumplessGrinch @themattsimpson Don't understand it, haven't tried hard, my logic background is weak. @Meaningness thinks it's wrong.

@St_Rev @themattsimpson tbh I haven't read many criticisms of it, should read more.@Meaningness do you have a piece on the topic? -
@GrumplessGrinch Pearl’s thing is not “wrong,” but is applicable only in limited, highly-controlled circumstances. -
@GrumplessGrinch Also, it doesn’t correspond to ordinary-person understanding of causality (only statistician’s meaning; not same). -
@GrumplessGrinch It assumes you have a small, fixed, perfectly-defined set of variables, and only a subset of possible interactions between. -
@Meaningness In practice this is often useful. -
@GrumplessGrinch Yes, it’s fine; just not a general account of causality in either common-sense or scientific understanding. -
@Meaningness It's not *tractable* at scale, I agree. But what does it fail to account for? -
@GrumplessGrinch commonsense version has objects or events as causes; Pearl version has only variables.
