Knowledge structuring and representation in learning based on active recall (Wozniak)
As the analysis of intractable items in numerous databases show that numbers take the lead in making items indigestible to human memory, the use of numbers in databases of all sort should be limited to the absolute minimum. As the discussed database on microeconomics was notably sparse in numbers (mathematical formulas do not count here), the above example [ed. Ford Motors early edge example] was a notable exception, and, perhaps for that reason, did not cause any serious recall problems. However, had there been more such numerically saturated cases, the issue could have started being a problem.
