Thanks for sharing! This actually updates my understanding of the community a bit, am excited to go deeper on this.
I saw a few other folks here also talking about that blindspot. Would be curious to know whether they (like me) were simply unaware, or whether there's still serious reasons to think we're underappreciating the murky areas beyond strict experimental control.

I like that this question allows to some extent to incorporate discussions about EA's blindspots in 'messy' processes like politics / institutional change etc. by asking what to do in such areas.
