In ecology, observational researchers seem to think no assumptions can allow you to interpret a correlation as a causal relationship, and experimentalists seem to think you don't have to make any assumptions to do the same. Wrong. Both groups need to make same assumptions!👇[1/7] Contrast this paper about ecological experiments from @LauraEllenDee @MeghanAvolio K.Kimmel
