In a powerful address, Harvard professor Arthur C. Brooks has warned that smartphones have trapped Western civilisation — especially Generation Z — in a “left-brain simulation”. This digital shift starves humanity of the right-brain complex experiences essential for purpose, love, and faith. He articulated three actionable steps to escape this technology trap, rebuild real human connection, and reclaim a truly meaningful life.

Speaking to thousands of world leaders at this year’s Alliance for Responsible Citizenship (ARC) Conference in London, Arthur C. Brooks challenged the idea that the crisis facing Western civilisation was primarily one of politics, society, or values.

The West’s Crisis of Meaning

He argued that the “deep, underlying” crisis was one of meaning, and suggested that we already have the answer to that crisis.

A respected author of thirteen books, including the #1 New York Times bestseller Build the Life You Want, Brooks teaches university courses in what he calls the “science of human happiness”. He holds a PhD in public policy analysis and served as a military operations research analyst for Project Air Force. 

Currently, Brooks serves as the Parker Gilbert Montgomery Professor of the Practice of Nonprofit and Public Leadership at the prestigious Harvard Kennedy School and Professor of Management Practice and Faculty Fellow at the Harvard Business School.

He called this loss of meaning a “psychogenic epidemic” — “an epidemic that creates misery with no biological origin”.

“Around 2008–9, something happened. It’s almost like some diabolical force entered the lives of young adults, possessed their souls, sucked the meaning out of their lives…”

This drastic rise in the percentage of young adults who see their lives as meaningless has a simple explanation.

Right-Brain, Left-Brain and Digital Technology

Drawing on the work of British psychiatrist, philosopher and neuroscientist Iain McGilchrist, whom he referred to as “one of the great figures of our time”, Brooks explained the concept of “hemispheric lateralisation,” which distinguishes between the functions of the left (complicated) and right (complex) hemispheres of the human brain.

According to Brooks, the left hemisphere of the brain is devoted to the complicated problems of life, while the right hemisphere deals with the complex problems.

“Life needs both hemispheres. You need to know why you’re doing things, and then you need to know how to do them. You need to know why you love the people that you do, and then you need to go out and figure out how to support your family. That’s how the brain is supposed to work.”

When an individual looks at a smartphone, however, they push their brain’s activity to the left side of the brain: “away from mystery and meaning and to information and things”. This is having an impact on meaning that is difficult to quantify.

Says Brooks, “We are living a left-hemispheric existence, but we crave right-hemispheric meaning — and it’s ruining our lives.” While people crave the meaning and mystery that is so fundamental to human existence, we are forced to live within a “left-hemispheric simulation” of that meaning.

Whereas people long for love and connection with other people and — most importantly, with the divine — digital technology represses our cognitive ability to engage in and enjoy such relationships, which rely on the right-hemisphere of the brain. In our digitally-saturated, left-hemispheric world, young people are being taught that the formula for life is: “Love things”, “Use people”, and “Worship yourself”.

Yet this is not the way humans were designed to function.

3 Practical Steps to Push Back

So what can we do about it?

In his speech, Brooks outlined three steps we can take to “escape the Matrix”.

Firstly, we must “rage against the machine” both individually and at a policy level. Individually, this means that in our own lives, we must radically rethink our relationship to technology — especially smartphones.

“I promise you: you — I mean every one of you — are addicted to your devices. It’s almost impossible that you’re not, unless you’re a Carthusian monk.”

At a policy level, Brooks urged us to do “something”. One way to start would be to completely ban phones in schools — from kindergarten to the doctoral level. Thankfully, Australia has made good progress on this score.

Secondly, he argues that people must “go deeper”, emphasising the most significant questions of life. We need to grapple with fundamental questions like “Why am I alive?” and “For what would I give my life?”

“You know the essence of humanity? It’s not answering questions. It’s not information. It’s asking questions. What makes you human is asking questions. That’s the difference. When you ask a question that you can’t Google, that’s a right-hemispheric experience.”

Finally, he said that we need to replace the “counterfeit formula” that the world is teaching our young people with the true formula. Instead of loving things, we must use things. Instead of using people, we need to love people. And instead of worshipping ourselves, we must worship God alone.

It is only when our relationships are so ordered that we can break the stranglehold of digital technology and experience genuine meaning and purpose in life.
