Who says the Earth revolves around the Sun?

If you were like me, you were probably taught that the Earth revolves around the Sun, and that it takes one year – a bit over 365 days – for the Earth to complete one such cycle.

And you probably also learned that we didn’t always believe that.

You might have learned about Ptolemy, who believed that the celestial bodies revolved around the Earth. It seems impossible to believe now, but that was the established wisdom for thousands of years. People were executed for disputing this scientific “fact”.

When Copernicus came up with his idea of the Earth revolving around the Sun, it didn’t make sense. The scientists of the day disputed his claims and showed through “science” that he was ‘wrong’, by demonstrating that his theories couldn’t explain what was happening any better than the established wisdom. In fact, Copernicus’ model offered worse predictions than Ptolemy’s model.

But with contributions from Galileo and Kepler united under Newton, our world experienced a paradigm shift (in the original/ Thomas Kuhn sense of the term). And suddenly our textbooks were rewritten. And so “The Sun revolves around the Earth. The Sun has always revolved around the Earth.” became, “The Earth revolves around the Sun. The Earth has always revolved around the Sun.”

Now, with the benefit of hindsight, we of course know that we know the truth.

And yet, do we? Perhaps one abusing ‘Relativity’ might posit that it all depends upon where you are stationed – that from the perspective of the Earth, the Sun does revolve around it and vice versa. And maybe they are both wrong.

Such is the nature of “science”: The perpetual quest to prove oneself wrong.

The special challenge falls on those individuals who lead periods of revolution. Scientific, cultural, social, linguistic. Whether they are the revolutionary leaders of climate change or economics or politics or even intelligence.

You see it in someone like Howard Gardner in positing Multiple Intelligences back in 1983. Or Edward de Bono’s “Lateral Thinking”. Or Mihaly Csikszentmihalyi’s Flow. From ‘ridiculous’ to ’self-evident’ in but a short few years.

If we are going to support and facilitate the development of more of these game-changing Great Minds – people with “capital C” Creativity – what sort of systems, policies, procedures, experiences and opportunities might we want to create?

In the past two weeks, I watched my four-month-old son learn to blow raspberries. Inspired by reading that this would be good for his language development (seriously!), and knowing that his mother can’t blow raspberries, I made the sacrifice and regularly blew raspberries at him. He was surprised at the start, then he started laughing. Then he started trying it out for himself. It took a while, and he ‘fell over’ a bunch of times. Even now, his raspberries are particularly sloppy. But he watched me and he did it – today, he can reliably exit a room and blow me a raspberry!

Interesting skills are usually the most difficult to transfer. We can learn Newton’s Laws, but it’s another story entirely to learn to think as Newton thought. Those tacit and almost invisible skills that sometimes leave behind traces of brilliance are the ones where we lack the language to teach the skills. Often we lack the explicit knowledge as to what is being done at all. Yet an infant can learn without language. They just look out at the world with eyes wide open and a willingness to explore, experiment and experience.

Ultimately, most of what we learn is false. It’s our best guess, but at best it’s almost certainly wrong or flawed. We want to get to those moments of joy and pure experience when we can create genius.

I wonder what would happen if  we would just choose to put our desire to control to the side, and accept the ambiguity, the obstacles and the knowledge that even our best work will probably be wrong. And just keep blowing raspberries.

Keep practising – especially as you get older!

A few months back I did a martial arts session with my original instructor. It had been a long time and I was far from my best, so I paired up with a relatively junior student for some padwork.

He was young and strong and had been training hard for a few months.

Little did he know that I had trained since before he was walking. It began when I was 15, and I loved spending hours in the hall, relentlessly asking questions of my instructor long after the class had finished. So when I hit him, he was pretty surprised :)

When I step back into one of those same classes today, I remember most of the techniques but my skill level has suffered – perhaps more than I would like to admit. But I’m still not your average beginner.

In my first session back, it’s best if I just watch, or pair up with a beginning student. In my second session back, I can pair up with someone who has been training for a few months. And after a few weeks, I’ll expect to match it with the guys who have been training for a year or more.

But why? Why can we get so much better so quickly?

It’s the same with older experts. After playing at the top of their field, they will stop doing so much deliberate practice. The sportsperson won’t be competing so they won’t be training – at least not as much. The doctor won’t be studying and maintaining their skills through regular patient contact. The linguist will struggle in a language after not having used it for a while. We all get ‘rusty’.

If you’ve been reading much of what I’ve said before, you’ll know that deliberate practice is important for skill acquisition. But deliberate practice is also important for maintaining those skills.

(So if you find yourself competing with someone who seems to be ‘past it’, you might want to check how much practice they have been getting lately.)

It’s like there is a ‘trait’ component and a ’state’ component of skill. The ‘trait’ component is how good you are at your worst – when Lleyton Hewitt plays tennis at his worst, he’s still much better than most of us. But there is also something else: “How good are you today?” We could call that part our ’state’ skill level because it depends upon our state in any given moment. To compete with the best, you might need to have a high level of “state skill” and combine that with being at your best on that day with a high “trait skill”.

As you get better, you not only polish your performance skills, but create mental and physical adaptations. When you start driving, it’s hard work to keep the car in the right gear, to check the mirrors, steer and keep a safe distance from the cars around you. After a while, you just need to think “turn right” and you can. Some of this comes from tasks becoming automated so they require less attention, some of it comes from using a better strategy and having better technique. But even the best of us can have a bad day – so there is a ’state’ component and a ‘trait’ component.

The great thing about deliberate practice enhancing our ‘trait skill’ level is that once you have developed a high level of performance, you can take those adaptations with you without too much effort.

It’s the ‘hard work’ of deliberate practice that creates a context for these adaptations. It’s hard work because we are learning to do things differently. Rehearsal or playing the game can give you ‘experience’ but this polish doesn’t improve the stone. Deliberate practice upgrades the quality of the underlying stone.

So, as you begin 2010, I hope that you can find ways to upgrade your skills, not just getting a little better…

Genius is a choice.

Being the best is a way of life, not a job

To be the best at what you do takes an extraordinary commitment. You’ll need to practise – spend hours and hours focused on getting better. You will change the way your brain works by altering the very connections of the neurons, and indeed every cell in your body.

It’s a big deal.

And you’ll want to do it every day.

Not just 9am-5pm, Monday to Friday. Not even Monday to Saturday. But every day of the week.

Our good friends Ericsson, Krampe and Tesch-Romer found back in 1993 found that experts practised the same amount every day, including weekends.

So pick your area and start practising. Every day.

Isn’t it just about experience?

Some people say that you just have to work harder to get better. It seems to make sense, and appeals to the virtue of ‘hard work’.

But the truth is that it’s not that simple, is it?

There are some people who work really hard – who spend hours practising or playing – but who don’t get better. Maybe you were one of them.

Sometimes we can do things a lot and not get better at all. In fact, sometimes we get worse!

When I was playing tennis as a child, I would hit the ball and play tournaments and show up to expensive coaching sessions. And at my best I consistently got mediocre results.

The trouble was that I didn’t get feedback. I was practising but I wasn’t doing it the way I needed to if I wanted to actually get better. Instead, I rehearsed the skills I had over and over until I could play ‘well enough’. But I didn’t get better than that.

Nobody told me what I needed to do and I didn’t figure it out for myself. Maybe I could have but I didn’t.

As you read this, you have been walking for a long time. Yet how much better at walking are you today from last year?

Deliberate practice goes beyond just doing the same things over and over again, and instead is focused on actually getting better. It’s about finding ways to push yourself – to make your best even better – and it’s not always easy.

Sometimes you might need to invent ways to challenge yourself.

Because that is what the best of the best will do.

K. Anders Ericsson on “What it takes”

The Cambridge Handbook of Expertise and Expert PerformanceAs I was rereading the Introduction of “The Handbook” this morning, it occurred to me how remarkable it is that there is actually a formal domain of expert performance at all.

Being an ‘expert’ is simultaneously honoured and stigmatized in much of the world. In some parts of the world excellence has even been systematically repressed. And yet, we still want to know “what it takes”.

Successful people spontaneously do things differently from those who stagnate. In particular, they have different practice histories. We consistently see that they engage in “deliberate practice” – they work to innovate the way they do what they do.

You can read more about what the lead editor of The Handbook has to say in an interview with Fast Company here.

Being excellent isn’t easy. But it is a lot more simple than you might believe.
