In her book "The March of Folly: From Troy to Vietnam," Barbara W. Tuchman explores the dangers posed by deeply entrenched biases, particularly in leadership and governance. She argues that when individuals in positions of power hold strong prejudices, their ability to make sound decisions is severely compromised. This can lead to misguided policies and ultimately, negative consequences for society.

Tuchman’s insight highlights the importance of critical thinking and open-mindedness in governance. Leaders who are guided more by their biases than by reason and evidence risk steering their nations into turmoil and conflict. By recognizing and addressing these ill-formed thoughts, governments have a better chance of making informed choices that benefit the public.
