When noisy decision-making becomes a strategic advantage

Phys · · 661 words · By Michael Hesse

The article discusses a study published in the Proceedings of the National Academy of Sciences regarding evolutionary game theory. It explains how 'noisy' or less sensitive decision-making can provide strategic advantages in specific scenarios, such as the 'snowdrift game,' compared to highly sensitive behavior.

“Coordination games follow a different trajectory again. Here, the evolutionary process can reach a branching point at which the population begins to diverge in opposite directions. Some individuals tend to become less sensitive, while others become ever more sensitive.”
