Ever looked at numbers and thought no way these are accurate - Benford’s Law exists for a reason

Added: 2026-05-17

[00:00:00]Did you know that there's a mathematical pattern hiding in almost every natural occurring set of numbers? Most people have never heard of it and forensic accountants use it to catch people who are lying about their sales data because fabricated numbers almost always get it wrong. Frank Benford was a physicist at General Electric in 1938 [music] and he noticed something strange. In natural occurring data, whether it's populations, rivers, lengths, stocks, [music] prices, invoice totals, the number one appears as the leading digit about 30% of the time. Two appears about 17% of the time and the higher the digit, the less it appears. The distribution is not random. It It follows a specific logarithmic curve and shows up in almost every real world data set [music] whether the data has anything in common or not. The reason this matters for marketing is straightforward and a little uncomfortable. When humans fabricate numbers, we intuitively spread them more evenly.

[00:00:55]>> [music] >> We think random means balanced. We pick sixes and sevens and eights because one [music] feels too obvious and any data set where the leading digits are too evenly distributed is a data set that a human has touched. Marketing agencies have been caught inflating campaign performance numbers this way. Benford published his findings, named the law and went back to work in physics.
