this is Arina Bones levels of prescience! maybe we all really knew the future all along!? ... but kudos for clearly stating the limitations - it seems that predicting actual behavior in the field is much more tricky!
An important limitation: LLM predictions were about 2x too large, on avg. Accuracy also was lower for small effects, treatments on stable attitudes, field outcomes, and non-text treatments. LLM predictions can help inform research but should not replace human evidence.
