The definition above suggests a correlation between an individual’s expertise and intelligence and the cognitive load of performing a task.

The measurement and conclusion on expertise and intelligence are very much related to previous chapters (as expected). Intelligence will correlate to the amount of information that can be stored, its size, or the limitation of working memory. Expertise correlates to the active use of memory or System 1 thinking, and the timespan of active usage is related to Ebbinghaus’s forgetting curve.

We all hire intelligent people and seek to maintain focus on growing expertise and creating opportunities for people, enabling us to showcase that expertise within a software development environment. The more we can expand the timespan and increase the frequency of actively using existing knowledge (=expertise), the fewer working memory resources will be required to perform the tasks.
