Some people love to cite statistics. They will crunch numbers to support their point on the assumption that their command of data clinches their case.
While powerful data has its value, focus less on the figures themselves and more on interpreting them accurately. The best negotiators don't accept statistics as gospel; instead, they ask, "What do you conclude from that data?"
By inviting a data-driven speaker to shift from reciting numbers to interpreting them, you encourage a richer, more revealing dialogue. You might draw different conclusions from the same statistics or question a researcher's protocol.
Examining data with a critical eye also casts you as a keen thinker who's deeply intelligent and intellectually curious. Colleagues will anticipate your questions and prepare a more rigorous, cogent analysis as a result.
