None of this is to deny the power of practice. Nor is it to say that it’s impossible for a person with an average I.Q. to, say, earn a Ph.D. in physics. It’s just unlikely, relatively speaking. Sometimes the story that science tells us isn’t the story we want to hear.
Malcolm Gladwell pushed the debate of how experts became experts into the mainstream with his highly successful book “Outliers: The Story of Success“.
I remember studying expertise behaviours and acquisition in my undergraduate psychology course, and most of the cited references were from the 1980s. So there’s nothing new about the ideas, they were just repackaged and marketed to the public.
If you had read it, you would have realised that the study is conducted on youths who scored highly on SAT, and their achievements are measured by the attainment of a PhD. Can the result then be generalised to other fields such as music, art, business, engineering, medicine, IT, and so on?
Perhaps some fields more than others, we should be cautious about over-extending and over-interpreting the findings of scientific studies.
We always have to be careful about how data and results from scientific experiments are interpreted. If possible, it’s best to go back to the root source. Don’t rely on a newspaper journalist to interpret for you.
