In her lecture, The Hungry Mind: Origins of Curiosity, Susan Engel of Williams College beautifully explains the benefits of curiosity not only on student motivation, but learning. See Engel's talk below:
Corroborating Engel's conclusions, Min Jeung Kang and his team at Caltech concluded via fMRI, in an article titled The Hunger for Knowledge: Neural Correlates of Curiosity, that when an individual is curious, they are able to negotiate complexity in the content domain they are learning, as well as unrelated content domains! Perhaps it is the Biology teacher in me, however I do not think it is a reach to say that Kang's observations can be extrapolated to a Darwinian hypothesis. That is to say, increased curiosity = amplified awareness = survival fitness.
After reflecting on Engel's video and Kang's research, I slipped into a nerdy state of reflection regarding the relationship between curiosity, health, survival, etc. I have always been a very curious person (to a fault at times...), and was immediately "curious" about any direct experiences with the relationship between curiosity and "fitness" to survive. After reflecting, it was clear that my current obsession with curiosity isn't by accident. Without exaggerating, my curiosity has indeed saved my life. Below is a workflow of thoughts that emerged from this reflection. TMI warning:
