3.5 doesn’t necessarily round to 4…

It’s Basic Math, Isn’t It?
Somewhere in late elementary school we all learned about rounding numbers. If the numbers after the decimal are .5 or higher, you round to the next whole number, right? 3.5 becomes 4. 4.5 becomes 5. Etc.

So why is it that some reviewers on Goodreads and Amazon include a rating with a half star in the body of the review but don’t round up to the next whole number of stars in the official review score? Here’s a hypothetical example. The body of the review says 3.5 stars but the reviewer assigned a score of 3 as the numeric star rating — and its the 3 that goes into Goodreads’ calculations. Did the reviewer miss that day in elementary math? Did the book lose out on a full star in that review? No. The system is working exactly the way Goodreads intended.

What’s Going On Here?
Before I launch into an explanation, let me provide a little background about my perspective. I have a doctorate in an applied area of social sciences, specifically health economics and outcomes research. Part of the quantitative training in this field includes study in survey analysis, psychometrics, etc. In my non-book-writing career, I’ve spent considerable time designing and using instruments that collect subjective ratings from individuals.

I provide this background not to convince you to believe me. I do have expertise in this area, but more importantly, I want you to know my perspective when I dig into this issue. I’m looking at it from the cold, objective perspective of a social science researcher and not as an artist interpreting how others are judging my work.

With that out of the way, let’s get to the numbers. In fields like engineering, physics, and chemisty, rounding works exactly the way we learned when we were young. That’s because we’re taking objective measurements of a property or attribute, like weight or length. If you and I both use the same measurement device, we should always get the same answer.

A book star rating is an entirely different animal. It’s a subjective summary scoring, where each reviewer uses different criteria. The same reviewer might give a different score on a different day due to mood, recollection, etc. It’s messy stuff. So 4.5 stars is not a robust measurement that is meaningfully different from 4.4 stars or 4.6 stars. It’s a hand-wavy way of saying that the reviewer thought the book was better than 4 stars but not worthy of 5.

So why don’t Goodreads and Amazon allow reviewers to use half stars? Aren’t they losing information by forcing the reviewer to round? Nope. They force you to round so that they gain information. Wait… How can they gain information by reducing the precision of the score? Ahh… That is the money question. It’s the reason they don’t have half stars. They are asking you to make a distinction that only you can make. That book you’d like to rate 4.5 stars… Is it more accurate in your mind to rate it a 4 or to rate it a 5? Now the reviewer has to make a call. In the hypothetical review of the book above, where the body of the review says 3.5, the reviewer made that call and said, in their mind, it’s more accurate to go with 3. (Social scientist me says well done. Artist me says dang it!)

A single score doesn’t tell you much, but if a lot of reviewers make the same call (to round up or down), the resulting average score is pushed the direction that matches that sentiment. If the reviewers are all over the place, the up-rounders and down-rounders should offset each other.

A Question of Fairness
I’ve seen a number of authors complain about improper rounding on Twitter. As you can see above, I don’t think they are right — at least not in terms of math. But I have seen a different complaint that needs acknowledgement: that persons-of-color receive ratings that are disproportionately rounded down. Since star ratings are subjective, biases definitely play in, so that is certainly plausible. (If anyone can point me to a paper or some analysis on this, I’d much appreciate it.) But if that is happening, it’s not due to a lack of precision (or what I would call false precision) in the rating scale; it’s because some people are jerks. I don’t think the jerkiness of some rating randos changes any of what I have said above. Bias is a separate problem that plagues reviews.

Amazon tries to deal with bias and rating reliability through some black box weighting of reviews in the calculation of average ratings. So two people’s 4 star reviews don’t necessarily count the same. (I’m not sure if Goodreads does this. They’re owned by Amazon, but Goodreads seems to be more like the Wild West with reviews.)

This post is long enough already. I’ll write about bias in reviews in a future post. Stay tuned.

Finding Time to Write

I’ve written two 100,000+ word novels in the last several years. I’m not breaking productivity records or anything, but I’m pretty happy with my output given that I also have a very demanding job and still make time for family and exercise. I frequently get asked how I make time to write. Honestly, it doesn’t seem that tricky. Let me examine why that is.

So how much time writing am I really spending? I’m not punching into a timeclock, so I’ll have to estimate. Including editing and making revisions, I’d say each block of 1,000 words has about 10 hours of effort behind it. My two books have around 215,000 words combined, which would equate to 2,150 hours. That’s a year’s worth of work at a 9-5 job, but it’s been spread over about 4 years. So, 500-600 hours a year, or 10 hours a week.

Where do those 10 hours come from? Here’s what I do:

  1. Ruthlessly prioritize. For me, it’s: family, work, exercise, and then writing. That means everything else gets pushed to the back of the list. Some stuff never gets done, or it gets done the expensive way: hiring someone else to do it so that I have time to write.
  2. Take the time when it’s there. Some weeks everything comes together: I’ve got more available time and the words are flowing. Other weeks (or even months), work and family obligations leave no time to write. So I try to make the most out of time when I know I have it. I go through productive bursts, and then I’ll have droughts. It all averages out.
  3. Remove the time-suckers. I love to read and can get lost in video games. It’s best for me not to own the latest Dark Souls game until I’m waiting on beta readers. Otherwise, it will call to me, and games occupy that same time slot as writing.
  4. Live with less sleep. Unfortunately this one is the truth. It’s probably not the healthiest thing in the world, but I sleep about 6 hours a night. Always have.
  5. Have an understanding with my wife. This one is the most important, by far. Fortunately, my wife is a writer as well, so she knows the time it takes. We protect each other’s time even more fiercely than we protect our own.

I said it doesn’t seem that tricky, and it’s not. It’s straightforward — but that doesn’t mean it’s easy. It takes constant effort to make time, and sometimes life conspires to keep you away from your project. That’s okay. In the long run, you’ll get that book done if you just keep plugging along.
