# 2020 Review: Final Voting

*Click* [*here to begin voting*](/reviewVoting/2020)*. Click* [*here for a general overview*](https://www.lesswrong.com/posts/M9kDqF2fn3WH44nrv/the-2020-review) *of the 2020 Review.*

We're now in the final week of the LessWrong 2020 Review. We've had over a month of preliminary voting and discussion. Now it's time to finalize our votes. In this post I cover how to vote, why to vote, and what will happen with the outcome (in no strict order).

The winning posts will be assembled into the longterm annals of the [Best of LessWrong](https://www.lesswrong.com/bestoflesswrong)[^vbergmv1kbn]. This year, each top-rated post will be displayed with a donation button for its author, so readers can directly show their support for posts that were important to them.

The Best of LessWrong: where we remember the greatest contributions

Quick Recap on The Review
-------------------------

The LessWrong Review has two major goals. 

*   Improve the LessWrong community's longterm feedback and reward cycle.
*   Build [common knowledge](https://www.lesswrong.com/posts/9QxnfMYccz9QRgZ5z/the-costly-coordination-mechanism-of-common-knowledge) about the best ideas we've discovered on LessWrong.

Voting sends a signal about which posts were most important. This can feed into various compilation and distillation efforts. 

Who Can Vote?
-------------

All users registered before 2020 can vote. The LessWrong curation team will weight the votes of users with 1000+ karma more highly when assembling sequences, books, or other projects.

How do I vote?
--------------

Go to the [Review Voting page](https://www.lesswrong.com/reviewVoting/2020). There, you'll see posts that you haven't yet voted on sorted first, with posts you've previously given a karma-vote to sorted to the very top (they have a green stripe along the left side. Strong upvotes have a darker green).

The posts will include the *reviews* that got written about that post. This is intended to help you make an informed vote. You can read reviews that look interesting or highly upvoted to get a better sense of how the post held up.

You vote by clicking buttons that assign a post a score. A score of 1 means roughly "this post was good." A score of 4 means "this post was quite important". A score of 9 means "this post was extremely important." A vote of 0 means "I don't have a strong opinion."

(A vote of "4" is 4x as strong as a vote of "1", a vote of "9" is 9x)

If you intuitively mark posts as "good/important/extremely-important", you'll probably do fine expressing your votes.

**Okay but I'm a nerd and like knowing the details of things. How does this work under the hood?**

The system is built on top of a [quadratic voting system](https://www.lesswrong.com/posts/qQ7oJwnH9kkmKm2dC/quadratic-voting-for-the-2018-review). In quadratic voting, you have a limited number of points to spend. You can vote things more strongly, but the cost of a vote increases at a quadratic rate. So:

*   A vote of "1" costs 1 point
*   A vote of "4" costs 10 points
*   A vote of "9" costs 45 points.

You have 500 points to spend. If you spend *more* than 500 points, your votes get proportionately downweighted[^6w2duaja6h6], which looks like this:

It's up to you whether to vote a lot of things at the strongest setting (and have the votes count less), or to limit yourself so that your strongest votes count for a full 9 points.

Happy Voting
------------

I'm excited to see how various posts fair. I'm personally excited for people to take the time reflecting a bit, seeing how various posts compared against each other and against an overall standard of "what was important?". Use your own judgment about what that means, and help shape the longterm record of LessWrong history. :)

If you have any questions, bug reports, mild irritations or suggestions on UI improvements, let me know!

[^vbergmv1kbn]: We're still making the final call of whether/how to make the posts into physical books. We're considering a lot of different options, including "similar books to last year", "custom textbooks that are more 'inspired by' than directly taking the winning posts", and "no books." 

[^6w2duaja6h6]: The quadratic formula here is (n^2 + n)/2, i.e. if n is 4 (a "medium vote"), you get a cost of 10. When you overspend, it divides the cost of all your votes proportionately by x/500, where x is however many points you spent. i.e. if you spent 550 points it'd divide all your vote costs by 1.1. Then, uses the inverse of the quadratic formula to calculate new vote-values.
