Are we getting dumber, or is intelligence evolving?
Quick! What’s Your Partner’s Mobile Number?
If you hesitated—or had no clue—don’t worry.
You’re not alone.
Most of us have stopped committing numbers to memory.
Why bother when our phones handle that for us?
A decade or two ago, knowing key numbers was essential.
Now, we simply tap a name or, better yet, ask Siri or Google to call for us.
This isn’t just about phone numbers.
It’s about a fundamental shift in how we interact with information.
Once, knowledge was something you stored in your head.
Now, it’s something you access.
The Evolution of Information Retention
Historically, the ability to retain and recall information was a mark of intelligence.
Before the printing press, information was a privilege reserved for the elite.
Books were rare, and education was an exercise in memorization.
Monks spent lifetimes copying texts by hand.
Scholars prided themselves on their ability to recall entire philosophical treatises.
Fast forward to the 19th century: the blackboard became the centrepiece of learning, a revolutionary step allowing collective education.
Then came the typewriter, followed by computers, and now AI-powered search engines that serve up answers before we finish typing the question.
In the last two decades, technology has rewired how we engage with knowledge.
The industrial era model of business, life, and education, built around retention and recall, is increasingly obsolete.
We no longer need to memorise vast amounts of data. Instead, we need to master how to find, interpret, and apply information.
What This Means for Education
Education systems have traditionally measured intelligence by what students can remember.
Exams reward those who regurgitate facts with precision.
But is this approach preparing young minds for a world where AI can recall information faster and more accurately than any human?
Consider the paradox: schools still test students on their ability to memorise, while outside the classroom, life rewards those who can use technology to navigate knowledge effectively.
Imagine a future classroom where memorisation isn’t the goal.
Instead, students develop information agility—the ability to find, verify, apply knowledge, and turn it into human wisdom.
We’re already seeing the shift.
Some schools now allow students to use the internet during exams, focusing on critical thinking rather than recall.
Adaptive learning platforms tailor lessons to individual strengths. AI tutors provide 24/7 personalised learning.
But is this happening fast enough?
The Workplace Implications
This shift isn’t limited to students.
It’s rewriting the rules of business.
Once, professionals were valued for their expertise—essentially, their ability to store and retrieve information.
Now, those who thrive are the ones who know how to connect dots, solve problems, and leverage the right tools at the right time.
Think about how we work today.
Do we need to remember every financial regulation, marketing strategy, or software function?
No.
We need to know where to find the information and how to apply it creatively.
This has massive implications for future workforce development.
- Traditional roles will continue to evolve: Routine knowledge-based jobs will be automated. AI accountants, AI lawyers, and AI doctors will handle standard cases, leaving humans to deal with complex, nuanced situations.
- Lifelong learning will become the norm: Professionals will need to continuously upskill, not by memorising new data but by mastering new ways to access and use it.
- Knowledge-sharing will be redefined: Businesses will rethink how they store and distribute knowledge. Internal wikis, AI-powered knowledge hubs, and real-time collaboration tools will replace static training manuals.
The Bigger Picture: Are We Losing Intelligence or Gaining Something New?
During a recent segment on Radio 3 Hong Kong, we tackled this very topic.
I posed a simple question: Do you remember the phone numbers of your three closest relatives? I
t’s a question that used to be trivial, but today, most people struggle to answer.
This shift isn’t just about memory—it’s about how we relate to knowledge in an age where instant access has replaced retention.
If you’re curious to hear the full discussion, you can listen to the segment (16 minutes 58 seconds)
The concern raised by studies, such as those from the University of Michigan and the Programme for International Student Assessment (PISA), suggesting a decline in human cognitive abilities—concentration, problem-solving, reasoning—leads to an interesting question:
Are we getting dumber, or is intelligence evolving?
Sure, we struggle to concentrate for long periods.
We outsource basic math to calculators.
Our reliance on GPS has eroded our sense of direction.
But in return, we’ve gained something profound: the ability to synthesise vast amounts of information, collaborate across the globe, and innovate at speeds unimaginable a century ago.
As we discussed on air, perhaps intelligence isn’t about what you know anymore.
It’s about how well you navigate the sea of knowledge.
So What? What Does This Mean for You?
For businesses, professionals, and educators, this shift demands action. Here are some key takeaways:
- Rethink Learning & Development – If your training programs focus on knowledge retention, you’re behind the curve. Teach employees how to find and apply information, not just memorise it.
- Encourage Information Agility – Instead of rewarding expertise alone, value adaptability. Promote curiosity and the ability to learn quickly.
- Leverage AI as a Thinking Partner – AI isn’t replacing human intelligence; it’s augmenting it. The best professionals will be those who know how to work with AI, not against it.
- Build Smarter Knowledge Systems – Whether it’s an internal knowledge hub, AI-powered research assistants, or collaborative platforms, businesses should focus on creating living knowledge ecosystems.
- Embrace a Global Mindset – As education shifts towards universal credentials and AI makes expertise borderless, businesses should prepare for a world where talent isn’t confined by geography.
Final Thought: The Future of Intelligence
The way we think, learn, and work is changing faster than ever.
We’re moving from a world that prized retention to one that values context, application, and innovation.
This isn’t the end of intelligence.
It’s the beginning of a new form of it.
So, the next time someone asks, Do you remember your partner’s phone number?—smile.
You don’t need to.
You’ve got bigger things to think about.
