Simple experiment: submit each day one link to Gwern.net + 2 links to other domains. These serve as both a rough control for that day's difficulty of front page, any benefits or penalties applied to my account, and repayment to HN for the potential spamming. per nathanael's post, I tried to consistently post around 10AM EST (I don't get up early enough to do 7-8AM EST). Apparently he's wrong? Oh well. https://news.ycombinator.com/submitted?id=gwern extract stats from https://hn.algolia.com/#!/story/sort_by_date/prefix/0/author%3Agwern ?

While using HN, as a sort of 'public service', I occasionally made sure to visit the [newest submissions](https://news.ycombinator.com/newest "New Links") page rather than just the [main front page](https://news.ycombinator.com/news) most people read. After a while, I noticed that the links I upvoted there seemed to be turning up a lot on the front page, more than I would expect from my usual pattern of upvoting perhaps 5 links out of the 30 available. A horrible suspicion struck me: could the apparent arbitrariness of what links made the front page be caused by the /newest page being *so* sparsely voted upon that a single upvote made a meaningful difference? ## Methodology I decided to do a randomized parallel groups experiment to test: On /newest, take the first 5 links (#1-5, to maximize impact), do a simple 50-50 randomization on each to decide whether to upvote or ignore (I have a shell function for randomization: `echo "$((RANDOM % 2 < 1))"`); and make no votes on any other /newest items (I allowed myself my usual browsing & upvoting on the main page while I was there). As I have 'noprocast' turned on for 180 minutes, each group of 5 links should have been separated by a minimum of 3 hours (more than enough time for all links to fall off /newest). This was typically done during HN's busiest hours: 11AM-midnight EST. I was not blinded during the experiment, but the writeup & list were never public while the experiment was running. I used my existing high-karma (>7k) account since there doesn't seem to be any weighting of upvotes, reading through ["Inside the news.yc ranking formula"](https://www.righto.com/2009/06/how-does-newsyc-ranking-work.html), ["How Hacker News ranking algorithm works"](https://medium.com/hacking-and-gonzo/how-hacker-news-ranking-algorithm-works-1d9b0cf2c08d) & [discussion](https://news.ycombinator.com/item?id=1781013). A power calculation for sample size is hard to do: I don't have a Poisson power function handy, and I don't expect the data to fit a Poisson too well due to the stark contrast between the front-page and /newest. (And I do want a well-powered experiment - the only thing more wasteful than an overpowered experiment is an underpowered weak experiment.) However, I do expect the necessary sample to be quite large by the standards of continuous normally-distributed data. Most submissions to /newest fail to gain more than an upvote or two, which means that most of the sample contains little information about whether the extra upvote helped them reach the front-page or not. Further, I don't just want to estimate whether the net effect of upvoting is >1, I would like a reasonably precise estimate of *what* the effect is: knowing that it's, say, +2-10, is not very satisfactory. ("The oncoming car is somewhere between 10 meters and a kilometer away.") All in all, I don't expect the necessary _n_ to be <200. I decided to stop at _n_ = 300. The experiment ran from 2014-03-16--2014-03-31. On 22 April, after doing my planned analysis, the results turned out to be as expected but weaker than I'd prefer (turned out a *lot* of the sample is just a waste as they are stuck at +1/2) and so I resumed randomization to get another 100 links or so. I stopped the additional randomization on 6 May. ## Analysis plan The analysis strategy is: #. a non-parametric test of difference in mean scores #. dichotomize the items by <10 as a proxy for having made it to the front-page for a meaningful amount of time, for a [logistic regression](!W) to estimate increase in front-page odds #. attempt a Poisson regression on scores, to extract an estimate of the difference in means #. something fancier, suggested by the data (such as a [mixture model](!W) of Poissons, perhaps, to split between front-page and non-front-page) TODO: extract page views & time on page from my old Analytics, letting me calculate 'how much time am I steering with, say, 10 upvotes on /newest?' ## URLs upvoted: https://news.ycombinator.com/item?id=7410094

https://news.ycombinator.com/item?id=7706882 https://news.ycombinator.com/item?id=7706870 The 2 groups are not exactly balanced due to the simple randomization. One URL suffered a typo and I could not figure out what the original was, so for one block I randomized an extra link (a #6). The _n_ should be divisible by 5, but is off by TODO 1; I think I must have failed to copy-paste one link at some point. ~~~{.Bash} for URL in `xclip -o`; do elinks -dump $URL | grep -E ' points* by '; sleep 2s; done ~~~ ## Analysis basic analysis: ~~~{.R} upvoted <- c(3,27,2,19,60,2,69,2,14,6,72,9,2,2,2,57,2,3,31,2,2,32,2,3,2,2,33,2,8,2,2,2,8,4,2,2,8,4,55,2,10,7,327,35,58,70,6,14,3,2,2,79,3,2,100,2,5,4,7,72,2,2,158,2,3,2,73,59,54,2,76,7,141,2,424,11,2,6,2,3,3,3,2,2,2,2,3,126,3,2,2,3,2,3,2,7,4,2,6,2,2,42,2,2,2,3,2,5,77,2,5,5,13,85,19,2,2,2,6,6,2,2,30,72,2,2,6,2,2,4,17,2) - 1 ignored <- c(1,1,1,2,1,2,2,1,1,2,1,2,5,154,1,1,8,2,1,2,1,2,1,1,7,1,1,1,2,329,5,1,1,94,2,1,1,2,1,3,1,1,3,132,1,2,1,2,1,2,2,1,3,2,1,3,1,3,2,5,3,14,62,3,1,1,2,12,112,1,1,2,6,3,2,1,1,1,1,14,1,1,1,2,1,39,4,3,1,1,1,1,9,3,1,1,84,1,5,4,5,1,1,4,270,1,1,1,1,1,5,1,1,1,1,1,3,1,30,5,244,1,1,45,7,4,1,5,1,1,2,1,2,4,1,1,11,61,1,1,1,82,1,2,8,68,7,2,4,89,5,62,25,2,2,2,1,124,179,1,2) wilcox.test(upvoted, ignored) # ...W = 11758, p-value = 0.09914 hn <- data.frame(Scores = c(upvoted, ignored), FrontPage = c(upvoted>10, ignored>10), Upvoted = c(rep(TRUE, length(upvoted)), rep(FALSE, length(ignored)))) library(ggplot2) qplot(1:length(Scores), sort(Scores), color= hn[order(hn$Scores, decreasing=FALSE),]$Upvoted, data=hn) library(plotrix) histStack(hn$Scores, hn$Upvoted, breaks=25) g1 <- glm(FrontPage ~ Upvoted, family="binomial", data = hn); summary(g1) # ...Coefficients: # Estimate Std.

If the effect on the first 5 is TODO, and the effect on the last link (#30) is 0, then a reasonable guess at the mean effect over all links is simply TODO/2. ## Reddit comparison One might wonder if HN is uniquely aberrant in this lottery; the most natural comparison is the social news site Reddit. I picked /r/prog (a very large subreddit comparable to HN in size) and manipulated their `/new/` the same way ### Data upvoted:
