Ask five assistants the same question and you’ll often get five different numbers. On 28 of the 71 questions where all five gave a percentage, we got four or five different figures.Note 6We compared each assistant’s headline figure for the same question. A range counts at its middle, and figures within 2 points count as the same.
One question, five answers, from 49% to 96%
Asked “What percentage of marketers use marketing automation tools?”, word for word, on the same day.

Every question where all five gave a percentage, one line each, from the lowest figure to the highest. Closest at the top.
Agreement feels like proof. It isn’t. All five gave the same figure on 10 questions, and of the 5 we traced, 2 were sourced. The statistics they repeated most, quoted by three or more, did no better: 11 of 29.
And four were quoted by all five assistants, with no study anywhere behind them.
