Four out of five dentists recommend sugarless gum for their patients who chew gum? Prove it. Show me the data—all the data.
It’s not that numbers lie; people do—or they mislead, at least, consciously or not. People are often wrong, inexperienced, shortsighted, and biased. People bring unspoken agendas to the table, consciously or unconsciously—a way of looking at numbers whereby they are hoping to be proved right.
We’re all guilty of it, and yet, most people trust data. Every day, I see people mindlessly sharing, tweeting, and retweeting survey and poll data, Web analytics, and infographics as if the Almighty had handed them down like the 10 Commandments.
Some are very authoritative; others are not. And that has me wondering whether we (as a profession) bring enough skepticism into the workplace.
