#Why you can’t base business decisions on numbers alone

I absolutely hate it when people disagree with me. Yes, it’s good to get more perspective and ultimately any idea is improved with critical feedback and I do everything in my power not to bully concepts through. But in that exact moment, when I’m stating my case, I can’t believe the other person can’t see my side of the argument — especially when I think the ‘numbers’ are on my side. 

There’s a great cartoon that very efficiently captures this awkward moment in meetings, when different perspectives clash. The cartoon shows two people fiercely arguing over whether the number on the floor between them is a 6 or a 9… and they’re both right.

I think many business decisions are hampered because people are looking for the facts and the proof — the absolute truth — so they can make the right decision. Unfortunately, life is more complicated than that. 

You could base all your decisions only on the facts, stats, or A/B tests, but we all know the answers you can get from them are only as good as the questions. They can also be affected by the person asking the question or the purpose behind asking the question.

Statistics and metrics are often represented as being unambiguous. “Numbers don’t lie!” they yell to your face, holding the printouts of the latest A/B tests between ‘beige’ and ‘beiger’ for your logo. 

That’s one view… but here’s mine: numbers lie like a motherfucker. 

Or rather, they can be made to lie. Numbers are like jelly, taking any form their holder wants to. You can cherry-pick the metric you think shows you the absolute truth, but deep down you probably know that the bigger challenge doesn’t boil down to this one single number.

Actually, I wouldn’t mind owning a shirt that says “Lies, damn lies, and statistics” with an asterisk behind statistics for “facts, numbers, and A/B test results” (quick note to self: start selling those).

The truth is life is fluid and unpredictable, and even the simplest decision can have a thousand variables that all impact the outcome and complicate the plot.
