Unlocking the Power of Metaphor in Understanding Science

Chapter 1: The Role of Metaphors in Communication
Metaphors play a crucial role in our ability to communicate complex ideas. As Richard Powers states in The Overstory, “The best arguments in the world won’t change a person’s mind. The only thing that can do that is a good story.” If facts alone were sufficient to convey ideas and inspire change, we might not need metaphors at all. Instead, these linguistic tools help us create vivid images and emotional connections, enhancing our ability to influence and persuade.
We’ve all experienced educators who illuminate intricate subjects through empathy and relatable pathways. Such approaches are essential to our language and understanding.
What is happening in our brains when we process metaphors? Why do they resonate with us so deeply?
Section 1.1: Cognitive Patterns and Metaphors
Metaphors aid comprehension by creating cognitive frameworks and linking abstract concepts to tangible experiences. Our brains have evolved in ways that blur the lines between literal and figurative language, resulting in a unique interplay of functions.
Neurologist Krish Sathian from Emory University investigated whether utilizing metaphors tied to our five senses could illuminate the brain regions activated during metaphor processing. Sathian's team presented participants with tactile metaphors, such as “he is wet behind the ears” compared to “he is naïve,” or “it was a hairy situation” versus “it was a precarious situation.”
Through fMRI scans, they discovered that the areas of the brain responsible for language processing activated whether participants heard literal sentences or metaphors. However, metaphors also engaged the parietal operculum, a brain region associated with the sensation of touch, which did not respond to literal phrases conveying similar meanings.
This indicates that, without the metaphorical context, an idea may lose its impact when encountered. When cloaked in metaphor, however, it travels familiar neural pathways, enhancing understanding.

Section 1.2: Bridging Experience and Understanding
Senses are more closely linked to our emotional centers than to logical reasoning. Every day, new information emerges, but our personal experiences may not always provide the appropriate framework for grasping these concepts. We tend to comprehend ideas better when they are presented in a relatable and emotional context.
Metaphors create beauty by employing shared language that transcends experiential boundaries, connecting with individuals where they are.
Thus, when we advise, “Don’t talk to their minds; talk to their hearts,” we imply that communication should engage the insulas and cingulate cortices—areas of the brain intertwined with emotion and understanding. This interplay may foster a more compassionate and interconnected world.
