On AO3, there's a fanfiction called 'Ian Malcom: The Hidden Years'. This one delved into his backstory and filled in some gaps that the original source material left open. It was a long read but very engaging as it added more depth to the character. There are also some great ones that explore his relationships with other characters from the same universe in different ways.
The main purpose of 'Outliers: Story of Success' was to explore the factors beyond individual talent and effort that contribute to extraordinary achievements.
