When most people think of scientific research, they may imagine test tubes, lab coats, and microscopes. However, many impactful experiments happen not in laboratories, but in office buildings, student unions, and even on social media. In two fascinating studies co-authored by Professor Theodore Allen of The Ohio State University, researchers show how the same rigorous logic that drives cutting-edge chemistry or physics can be applied to practical, everyday challenges, such as where to place a hand sanitizer dispenser or how to convince someone to get vaccinated. The studies, though different in their subjects, share a common theme that data and careful experimental design can make the world cleaner, healthier, and more humane.
