The section "(Don't) Shut Your π-Hole" discusses a particular debate within the field of chemistry. This debate arises due to the fact that molecules, despite being overall neutral, are composed of regions with positive or negative charges. Specifically, areas that lack electrons are termed either π-holes or σ-holes. The extent to which these regions mediate interactions between molecules is a topic of active discussion among chemists.

Dean J. Tantillo argues that these debates are beneficial as they prompt chemists to design new experiments and develop better drugs and materials. Such discussions enable chemists to formulate new predictions and design experiments that are testable. This, in turn, can lead to significant practical outcomes, such as the development of new cancer drugs​.
