To improve generalizability of our inferences from human subjects research, we should randomly sample humans from all over the globe. This is a difficult thing to do, and simple random sampling will never be possible. But there are other random sampling techniques we can explore to increase coverage. We propose a random probability proportional to size sampling at the country level, so more populous countries have more potential representation. With Big Team Science, this starts to become possible. Mixing this sampling with non-response bias weighting (country-level) can help us see how indicators like GDP, inequality indices, and nation-level indicators can, quantitatively, inform gaps in our understanding. Only through the work of distributed networks of researchers can we start working towards randomly sampling the globe. This is only a first step, and future steps will improve on this system. Discussion and feasibility and alternative ideas are welcome.
