#statstab #464 Should a pilot study change your study design decisions?
Thoughts: You shouldn't use the ES, but you can use the SD (see also #192) for planning.

White America, not the DSA, held the power to secure Harris. That’s where the abandonment happened. Everything else is deflection. #USPolitics #PowerAnalysis
Brookings: DSA ≈ 78,000 people in a nation of 168M voters.
Meaning: Even full unity inside the DSA cannot move a presidential outcome.
AI ethics debates are a distraction. The real fight is between governments trying to control models, and corporations trying to control governments.

#statstab #371 Safeguard Power as a Protection Against Imprecise Power Estimates
Thoughts: tl;dr - when replicating a study, use the lower end of the CI of the original study as your effect in a power analysis.
