@gotonura & I on what we can learn from the Special Feature, incl. the challenges of developing generalizable knowledge about institutions in complex social-ecological systems & of synthesizing empirical evidence in sustainability science [2/11] pnas.org/content/118/29…
#Meta-analysis: @tara_slough@dktr_dr@RoeeLevyZ & country teams use all the data for Big Picture meta-analysis. Read the individual studies below to see full richness of lessons learned about mechanisms & moderators of impacts across contexts. [3/11] pnas.org/content/118/29…
@deankarlan@chrisudry@Monica_Lambon & E Asiedu explore ethics in social science experimentation & propose that researchers use structured ethics appendices for more complete communication of the ethics of their experiments. [5/11] pnas.org/content/118/29…
#Water in #CostaRica: Maria Bernedo del Carpio @falpizar and I evaluate an externally encouraged, community-based monitoring program to improve groundwater management. [10/11] pnas.org/content/118/29…
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]
All causal analyses need to address plausibility of “excludability” assumption – whatever drives variation in causal variable (like experimental manipulation) has no effect on outcome except via causal variable. See papers above for what to do when assumption is violated. [3/7]
