Interesting. I think I see what he is trying to say. However I believe he may have made some assumptions that may have led him astray.
Allow me to define some words so I am clear.
Talent: Abilities that you are born with and may maintain throughout your life baring injury\illness.
Skill: Strategies, or techniques that allow you to efficiently apply your talent in a particular field of endeavor.
So for example Basketball. The talent for basket ball is your innate ability to coordinate your body in response to an external stimuli, the ball. Some people are naturally more coordinated than others. So they are seen as very talented. Thus they have a initial advantage over others.
The skill now is built on top of this talent ( no matter how much you have). Without the skill set for the particular sport all the talent in the world will get you no where.
- Dribbling the ball
- shooting the ball
- passing the ball
- running to get open for a pass or a shot
- understanding the flow of the game
- Defending the basket
the above skills are fundamental to the particular game of basketball. However they are based on the underlying talent of coordination. Which can be applied to many disciplines. This is why many athletes can and do participate in multiple sports at a time, like baseball, football, basket ball, cricket, volleyball,…etc.
Now, apart from the obvious ability to coordinate, a person can be born with some thing extra that may give them an advantage in a particular sport\endeavor.
In basketball the taller you are, the larger the advantage you have, when coupled with high coordination.
As a result the best in the world are typically above 6 feet tall, as seen by those that play in the NBA.
In the case of memory, we can see IQ ( I have issue with the use of IQ but that is a different matter ), we can see that as you talent. The higher it is the better for memory and brain activity.
The skills applied to that talent can be numerous:
- Memory techniques
- critical thinking techniques
- Decision Making
- Problem solving
- Sequencing
Just like in basketball the the more talent (IQ) you have the more of an advantage you have.
However no matter what level of talent \IQ you have, you can improve the results you get by applying skills needed by the particular endeavor you want to do well in.
It seems he only looked at memory champions or studies that only involved memory athletes.
As a result it would appear that only high IQ people have used the techniques.
That is erroneous, as I have been in courses with folks that admitted they do not have high IQ results and they did really well with memory techniques.
As a matter of fact they came to depend on the techniques with their jobs or getting certificates.
I even taught a few children some memory techniques and the improvement in what they can remember was hugh.
Most of these people will never contemplate competing but their lives have improve from the use of the techniques, as have mine.
Not everyone is looking to be an NBA player, however millions of people love to play the game, and have learned to apply the skills so they can play at levels they would not be able to without.
The same can be said for memory techniques. People have applied these skills to their lives, and gotten promotions, memorize entire books, gotten certificates, remembered information about family members, like birth dates, phone number, license plate numbers, etc that they would normally forget.
What I do agree with him on, is interest. If a person does not want to improve, or can not see themselves improving they will not apply the skills. If someone has an interest then they do well.
This happens for any endeavor, not only cognitive ones.
