Imagine locking your iPhone in a box for 14 days. No scrolling, no notifications, no instant dopamine hits. This is exactly what a CNN journalist recently did, collaborating with researchers from Western University in Ontario to measure his brain activity before and after the experiment.

The results were not just interesting—they were a wake-up call for the modern professional:

• Reaction times improved by 23%.
• Brain connectivity became more coordinated.
• Perceived concentration capacity saw a significant boost.

This isn’t magic. It is simply what happens when the human brain is no longer interrupted every five minutes.

The 47-Second Crisis The cost of our digital habits is becoming increasingly measurable. Researcher Gloria Mark (UC, 2023) documented a disturbing trend: the average sustained attention span on a single task has plummeted from 2.5 minutes to just 47 seconds in recent years.

47 seconds.

Think about the requirements of leadership. If you need to make complex decisions, maintain a long-term strategic vision, “read” the people in a room, or manage a high-performing team, you rely on specific cognitive functions: impulse control, emotional regulation, and goal-oriented thinking. These are exactly the functions that smartphone dependency erodes first.

Who is Using Whom? I am not suggesting we throw our devices away, but we must pause and reflect. We need to ask ourselves: Who is actually in control?

I recently went to lunch with a manager from a major industrial group. He had asked to meet to discuss a potential collaboration, yet he couldn’t stop looking at his phone and responding to messages. He was a “victim of notifications”—physically present, but mentally fragmented.

A Personal Rule for Better Connection As a personal rule, I now put my phone completely away during every appointment or meeting. I choose to give the person in front of me 100% of my attention.

I encourage you to try it. It serves the quality of your work, it shows respect to your interlocutor, and it protects your mental health. In a world of 47-second attention spans, being truly “present” is becoming a rare and valuable competitive advantage.

This reflection was inspired by the experiment conducted by Bill Weir (CNN) and the insights published in Il Corriere della Sera.
