[commenting note: for the love of God, there are so many places on the Internet where one may discuss tragic dogs, you don’t have to do it here]
I would like to say, up front, as a disclaimer, that I am absolutely not suggesting that anyone vote for these stories in the Hugos. What you decide to do with your own individual vote is up to you.
However, probably a lot of rationalists are going to get Hugo memberships for the first time this year so they can nominate HPMOR. [ETA: Note that Eliezer does not want you to purchase a Supporting Membership to WorldCon, if you otherwise would not, for the purpose of nominating HPMOR.] As a public service I am rounding up other fiction by rationalist and rationalist-adjacent people that I happen to think was notably good.
Feel free to suggest additions in the comments.
Dogs, by Alicorn. Society begins to take wild-animal suffering seriously and eliminates all animals. An exploration of what is lost.
Muse, by Alicorn. A horrifying short story about art and space colonization with a twist ending that will give you nightmares.
Threshold, by Alicorn. A short story exploring the ethics of eugenics.
Grownups, by Alicorn. A post-Singularity story about a child who died before the Singularity.
And I Show You How Deep The Rabbit Hole Goes, by Scott Alexander. Based on a Tumblr post, munchkiny as hell, and concluding with a ridiculously groanworthy pun, this story will have you cackling from start to finish.
Amazing Man, by Eneasz Brodski. A satirical superhero story about tragic dogs.
Water, by Alicorn. A fantasy novella about polyamory, transness, oppression, magic, terrible parenting, and water systems.
The Northern Caves, by Nostalgebraist. A Lovecraftian horror story that’s actually Lovecraftian rather than full of tentacles, combined with a loving pastiche of early-2000s Internet communities. One of the most stunning evocations of mental illness I have ever read. Make sure the lights are on.
Floornight, by Nostalgebraist. I have… actually not finished this one. However, it contains a character named Ratio Tile and has been often compared to Evangelion.
