What term describes a significant change or shift in thinking?

The term that best describes a significant change or shift in thinking is paradigm innovation. This concept refers to a fundamental transformation in the underlying assumptions and frameworks through which we understand and engage with the world. When a paradigm shift occurs, it often leads to groundbreaking ideas and revolutionary developments across various fields, leading to new ways of thinking that can dramatically alter industries, markets, or societal norms.

In contrast, incremental change refers to minor adjustments that improve existing systems without altering the fundamental framework. Transformational change, while it may seem similar, typically encompasses broader and more profound changes that can include paradigm shifts but doesn’t specifically denote a shift in thinking. Operational improvement involves enhancing existing processes or systems rather than redefining the way we think about them. Therefore, paradigm innovation is the most fitting choice for describing a significant and transformative change in how we perceive and understand concepts.
