Lieberman presents a lot of fascinating research—I'm curious how he chose which studies made the cut and if he faced challenges in balancing accessibility with scientific accuracy.

The approach is unique and makes the topic feel fresh. I'm curious whether this perspective was something Lieberman had in mind from the start or evolved during his research.
