Book incompatibility test

I see that our ratings for books we share are 75% similar. But the percentage I was talking about was the one on the next screen, when you click "book compatibility test" in the top-right. Then we get a score of 28%.
I guess you're right, it is just a bit of fun. Was just curious about how it works, though, and why the scores always seem so low.

I don't know exactly how the compatibility is scored, but the highest compatibility I've seen is around 45%. I think they choose random popular books within a category, and give each one a score between 0-6, 0 being not on your list, 1 being a To-read book, and 6 being a 5 star rated book. They then compare your "ratings" with the comparee's books and through the magic of mathematics come up with a number. (That's what I think, although they could stand naked in a circle of stones shaped like animals and sacrifice teddy-bears to the Percentage God for the number... No way to tell.)
Anyway, I know that there is a thread in the GR Feedback group discussing a way to search members as well as books, but I'm not sure how high that is on the "To-Do" list.
=) Hope that helps... somewhat!

Here's an example. Andrew doesn't have To Kill a Mockingbird on his list. I gave To Kill a Mockingbird 5 stars. The algorithm considers my rating and Andrew's to be a "terrible match." In reality, I bet that Andrew, like most people, probably has read the book, and probably even has good things to say about it. But he just hasn't happened to rate it yet. So it's a bit misleading to call it a terrible match.
I think the more useful number is probably not the overall compatibility, but the degree of similarity on books we've both rated.
Or, it could be that the algorithm uses the teddy bear sacrificial method that Becky mentions.
My two cents.


The highest I've seen is 54%.

As far as not having too much in common with people, don't sweat it. Part of the fun of this site is meeting people, perusing their bookshelves, and learning about new books you wouldn't have heard of otherwise.




I think it is odd because most of the books that my friends read, I am very interested in. I guess it's because there are so many books that I have yet to read and I try not to add them all to the 'to-read' list.

Click on your own profile. As your friends are displayed you can click on them and click on compare books. From there you can click on compatibilyty. As you are looking at posts, you can click on the posters avatar and do the same thing.



*shrug* Teddy-bear sacrifices by moonlight...?
I never noticed that before. Thanks. WE are about 40% sorry got distracted after I left so don't remember the exact number.


It seems that the lowest compatibility that I can have is 21%... A few real life friends are on my GR friend list even though they have 0 books in common with me, and yet they still have 21% compatibility.
It's very interesting!
I checked Fiona (33%) and Jeane (44%) against me....
And the strange thing is we have such a large amount of books in common....
Oh well. Like you all have said, I dont put much stock in it. If you cant get 100% compatability with yourself, then the thing is obviously wonky!

Ive also wished there was a way to find your book-twin on the site! as your likely to be interested in their reviews so worth befriending - wish they would do something, im sure its straight forward for technical folks to do!
81% is pretty good Andrew! we wont worry about the 21% on the next page :)..
p.s im only 30% compatible with my self - i knew there was something shifty about me .. myyyyyyyyy preeccciiiioooouuusss

I like Andrews idea... about finding a book twin.
Andrew, you should email Otis about it, or post a topic for it on Goodreads Feedback!!!

I am 19% compatible with myself.
Oh well, at least it explains why I can never make up my mind on what to read next...
Hey, just noticed that I don't even get a 100% rating on the 'Compare books' page: "You and yourself have 548 books (or 99.82% of your library and 99.82% of his library) in common."
Well, I think I am now 99.82% certain that the feature needs a little more work. Or, as Ofmatt put it: "So in other words, it's stupid."



I am just getting started on GB and fear that I have found my fellow addictive readers! I think it is interesting to see other peoples lists, especially the lesser compatability; it is a great way to find new things to read. I am such an eclectic reader that it is helping me branch out!

And, welcome Sue!




I am 62% compatible with myself and although my books are 100% similar, my ratings differ from themselves by 0.8%!
I attribute my high compatibility with myself to the fact that I have always worshipped Teddy Bears.


Hahah! That's actually very funny.
And thanks Fiona.

hehe Lori, are you still checking them out? :-) I guess it is a good thing not to have 100% with others, that way we find out about different books too.

a friend I've had for many years and I love getting her recommendations and she always has something intriguing to say when we get into our book discussions.
Well we scored very very bad.....so as far as I'm concerned....the compatability test cannot score chemistry!

The results? I have tried dozens of people, but my highest rating so far has been around 20%. Most are below 10%. So I am left with a few alternative conclusions to draw:
A. My taste in books is weird. Nobody is compatible with me.
B. I'm just not finding the right people - perhaps there's a less random way for me to find people with similar book collections?
C. The results are always quite low - around 20% is actually a 'good' score.
Anyone got any insight into how the book compatibility thing works, or what a good benchmark score is to indicate 'compatibility'?
