I would go a step further: NPS is a garbage metric. First, you start by assuming your customers can even reasonably ascertain their likelihood to recommend. They can't; there are people who answer 10 but will never recommend, and there are people who answer 0 but already have and will again. Next, you assume your customers are idiots and don't know how an 11-point scale works by adjusting the midpoint: Instead of 5,…
Not defending NPS here - I don't use it - but some of your assumptions are wrong. > They can't; there are people who answer 10 but will never recommend, and there are people who answer 0 but already have and will again. What matters with NPS is trend over time, and getting the numbers at a scale. Yes, there are people who randomly click on one end of the scale or the other, but the assumption is that on average the p…
That assumption is predicated first on the idea that people can and will tell you their likelihood to recommend within a reasonable degree of accuracy. I don't think they do.

But that's not the scale given to the respondent. The scale is given as going from "not at all likely" to "very likely" to recommend. There isn't an option for likely to recommend against. The low end of the scale probably captures some, but to assume it is near 100% is a mistake.
