Alicia Juarrero: Context Changes Everything (2023, MIT Press, The MIT Press)

Ch. 5 #JuarreroBook “Why context matters- an Interlude”

To illustrate the role of context ch. 5 uses C-19 and other infectious diseases to introduce widely used notions in epidemiology: direct, indirect, and total effects of an intervention such as vaccination.

These seem to be recast as ‘effects of context’ (e.g., ‘indirect effects of context dependent phenomena’).

J notes (p. 66) “Indirect and total effects are not anomalies; they are real, but top-down, mereological effects of a transformed collective dynamic (marked by a different periodicity and different parameters). It all depends on the role context plays in some disease dynamics.

and “independence or dependence on context is itself dependent on the scale and periodicity of that embedding context. It might be necessary to look further back in time and/or zoom out spatially to reveal the scale at which context dependence kicks in or washes out. Independence or dependence on contextual constraints …

2) Is any of this really about mereological relations? Herd immunity seems a bad example to me in that, here, the population seems to be nothing over and above the set of all individuals and all relevant dynamics are dynamics between those individuals

so are the highlighted indirect and total effects really “top-down mereological effects”?

(note there is nothing “top down” in a typical causal DAG representing relationships between such variables, see first paper under 1.)
