Okay, so

Imagine that someone asked you "how likely, on a scale of 1 to 10, are you to recommend this business to someone else?"

You give your answer, they note it down.

If you gave them a 6 or lower, you're a Detractor and probably going to poo poo-talk them.

If you gave them a 9 or 10, you're a Promoter and probably actively saying positives.

Otherwise you're neutral.

Total up all the promoters, subtract all the detractors, divide by the total number of people you asked, multiply the result by 100, and that's your Net Promoter Score, a percentile grade for How Good You Is. It's technically a proprietary system but it's so fuckin' basic bitch obvious that it's functionally public domain at this point.

For example, if you survey 20 people, get back 10 Promoters, 6 Detractors and 4 Neutrals, you have an NPS of 20 ((10 - 6) / 20) * 100).

You'll notice that it always gives a number between -100 and 100 so metrics geeks cream their pants about how easy it is to plot over time, and a lot of senior management types like it because it's a single, simple, holistic number they can look at and assign targets to, that the business can inevitably fail to meet because the score's swingy as gently caress and early gains decay like hell over time as the new product smell wears off and people get used to your system being a default.

Source: The company I work for is ten years old and senior management set an NPS score goal of 35 after the statistics guys manged to fluff a 30 out of a carefully selected group of customers.

Yeah, I really hate NPS. I’ve seen it do a lot of damage to companies, teams, and people, and earlier in my career I was complicit in managing to NPS as a metric I didn’t take the time to look at critically. I am trying to atone. I have multiple researchers in my division working on better ways to track word-of-mouth impact because I don’t want NPS to surface in our product even though our customers use it themselves and ask about it.

It's really not a thing that's useful as a one-off data point. The thing about those scales is they CAN be used over time to measure trends in an individual - if someone rates their pain as a 5 when they first come in but later rates it as a 7, you know something has gotten worse because their own subjective experience has changed, even if you don't really have any sense for how bad a "5" or a "7" actually is.

Yes, NPS is quite limited in telling you about many important changes in the underlying data, so it’s not really that useful in tracking changes over time in an actionable way!

I hate rating scales, from 1-10 "8 is average" corporate scales to product review 5-star scales, just every rating scale is bullshit because people are poo poo at them.

No, I'm not going to go through my music library being all "well, I like this song, but about half a point less than this other song I also like" like some dweeb. Spotify got it right by not having rating scales. You put a checkmark on the songs you like, and that's it. Nobody cares where you rate it on a 5-point scale.

Similarly, Facebook removed the stupid star ratings and now they just ask you whether you would recommend a page or not, and you can put a mini-review. That's how to do it.

This was an enormous fight between people who confused precision with accuracy (most PMs and about half the engineers) and those who wanted to optimize participation and clarity (UX, a couple rogue PMs, half the engineers, every single data scientist who even brushed up against it). I'm glad that the good guys won.

Bulldogs are pretty garbage as dogs. But all dogs are great.

I kinda wish there was a way of establishing the dumb/smart dimension better but unless they did something weird like rotate the dogs (not just flip it vertically) it'd be hard to convey.

As a dachshund owner I'm good with this chart (they're not that smart but they are awesome).

I have a pug, and despite about a year's worth of observation I still can't figure out if he's dumb as a brick or just intransigent. Possibly both.

In summation, pugs are the cats of dogs.

This change is stupid because we shouldn’t expect size and mass to have a proportional relationship.

We should expect mass should scale with the cube of neck size.

The new neck size is 0.955× the old neck size, so the mass should be 0.9553 × 20.5 kg = 17.8 kg.

That’s close enough to what we see on the graph.

Dogs aren’t radically changing shape. They’re simply shrinking.

Yeah the author's explanation on that one was muddled. They measures SHOULD be extremely correlated, even before you account for the length/volume scaling (and moreso after). And they are. But that correlation is also trivial/uninteresting, the dimensionality thing is trivial/uninteresting, and the appearance of an interaction can be confusing. So I'd separate the lines but NOT change the scales (just move one up to separate the lines). Or just pick weight and leave the neck size off the chart. But it's all pretty small beer I think.
