In a doctoral study, researchers attempted to understand how rats navigate forests by attaching spools of thread to them and observing their turning choices. While they measured numerous environmental factors, a simpler approach, inspired by an Australian study using only three variables, proved more effective. This highlights that scientific effort should focus on the most impactful variables, as extraneous data can obscure significant findings, a principle AI can help optimize.

Impact: High. This illustrates the critical need for parsimony in scientific research, ensuring that resources are focused on the most explanatory factors, thereby accelerating discovery and reducing wasted effort.
