What does the iceberg principle suggest about information in summary data?

The iceberg principle suggests that much of the valuable information in summary data lies beneath the surface, which aligns perfectly with the idea that good information is often hidden. In many cases, summary data only provides a superficial view of the entire dataset, similar to how the visible part of an iceberg represents only a small fraction of its total mass. While the summary may present a clear and concise picture, it fails to reveal the nuances, context, and complexities that are critical for a deeper understanding. Thus, the iceberg principle highlights the importance of exploring underlying data to uncover insights that are not immediately apparent from summary figures alone.
