- Patrick uses humorous anecdotes about avoiding holiday parties to illustrate this point.

- Statistical interactions, especially beyond two-way, are difficult to model effectively.
- Current methods, like using cross-products in general linear models, are simplistic and may not reflect real-world complexities.
