"Understanding is a delaying tactic" is a thought-provoking quote from Michael Crichton's novel "Sphere." This statement suggests that the quest for understanding can sometimes serve as a distraction or excuse to postpone actions or decisions. People may become too focused on comprehending a situation instead of taking necessary steps to address it, potentially leading to missed opportunities or unresolved issues.

In the context of the book, this idea highlights how characters grapple with complex and often overwhelming situations. They may become paralyzed by the need for clarity, which can hinder their ability to respond effectively. Ultimately, Crichton encourages readers to consider the implications of over-analysis and the importance of decisive action even in the face of uncertainty.
