By: Nicholas Carr

Introduction

Embark on a captivating exploration of the internet’s impact on our brains in the summary of ‘The Shallows: What the Internet Is Doing to Our Brains’ by Nicholas Carr. Discover how electric media have shifted our linear minds and delve into fascinating examples, such as Friedrich Nietzsche’s change in writing style upon using a typewriter. Learn about the internet’s role in altering human thought processes and memory, and the challenges posed by multitasking and constant distraction. Providing a rich analysis of historical developments as well as scientific evidence, this summary offers an engaging yet thought-provoking examination of the profound implications of our online lives.

The Medium Matters

Marshall McLuhan’s idea that the medium itself is more important than the information it conveys is still relevant in the era of the internet. McLuhan wrote that new media changes the way we perceive and think, and that the linear mind, which has been the center of art, science, and society for the last five centuries, is breaking down. The internet provides an overwhelming amount of information that is changing our thought structures to be more fragmented and discontinuous, while also rendering books a thing of the past. McLuhan’s idea that “the medium is the message” is exemplified in the case of Friedrich Nietzsche, who changed his writing style after acquiring a typewriter because “our writing equipment takes part in the forming of our thoughts.” In short, we must pay attention to the medium we use to consume information as it changes the way we think and act.

The Dynamic Brain

In the past, the brain was believed to be unchanging and machine-like, but J.Z. Young’s revolutionary idea in 1950 proposed that the brain is constantly changing. Modern research supports this notion, showing that the brain’s structure adapts to circumstances, creating patterns of usage. Focus and practice can change neural activity, making tools like instruments an extension of the hand. The brain’s infinite number of synapses link neurons together in circuits, creating habits and connections. The brain functions mimic the tools that interpret reality, changing the way humans think over time. This dynamic brain is not hardwired, making it adaptable to changing circumstances.

The Evolution of Reading and Writing

Reading and writing have changed our brain circuitry and human culture. Sumerian cuneiform and Egyptian hieroglyphics facilitated analytical thinking, while the Greek phonetic alphabet ushered in a literary culture. The written word liberated knowledge from memory and created neural space for abstract thought. Private reading demanded focused concentration, rewiring the brain to tune out distractions. Johannes Gutenberg’s printing press made books cheaper and more widely available, boosting literacy rates and expanding readership beyond classic and religious texts. The intellectual ethic of focused concentration dominated for five centuries, as books contained transferable knowledge and fostered a culture of learning.

The impact of the internet on reading

In the last few years, online activities have skyrocketed, with people spending twice as much time online as they did in 2005. Despite this, reading books, newspapers and magazines continue to experience a decline in readership, leading to newly designed libraries that prioritize internet usage over print. The internet, with its hyperlinks and interruptions, threatens reading by creating a need for constant stimulation, which is unhealthy for mental patterning. Even though web activity keeps the brain active, it damages certain paradigms of memory and affects comprehension and retention. Therefore, while the internet may be healthy for our brain in one sense, it is a double-edged sword that poses serious implications for the future of reading and our capacity for retaining knowledge.
