WebAlthough you can have "many" outliers (in a large data set), it is impossible for "most" of the data points to be outside of the IQR. The IQR, or more specifically, the zone between Q1 and Q3, by definition contains the middle 50% of the data. Extending that to 1.5*IQR above and below it is a very generous zone to encompass most of the data.
