The Takeaway
We spend millions on consumer polling, but AI human subject simulations can now mimic demographic responses so closely that the platform you choose for humans (like Facebook vs Prolific) causes more bias in the data than using a 'fake' AI participant.
From the abstract
Online platforms have transformed behavioral and marketing research. Yet identical surveys administered across platforms can yield markedly different results. We compare 7755 UK participants across seven major online sources (opt-in panels, Prolific, multi-source aggregators, and river samples from Facebook and Instagram) and a synthetic benchmark generated using the Electric Twin AI human subject simulation platform. Despite applying identical quotas and survey instruments, we find substantial
