Do the Experiments the Alignment Forums Ask for Most Stay Untested?

Every week, someone on LessWrong writes “someone should test this”. Most of these requests sit in a comment thread, and nobody counts them. We read every post and comment on LessWrong, the AI Alignment Forum and the EA Forum, from 2006 to November 2, 2026. That is 1.34 million texts. We wanted the tests that the most different people asked for, again and again.

In this article, we ask: do the experiments the alignment forums ask for most stay untested?

TLDR; No. Of the 50 AI asks that the most people made, 29 already have a published test that our search agents found and opened. 21 are still open. Repeats are also rare. Of 2,922 AI asks, only 94 experiments were asked for by two or more people, and no experiment by more than four.

Most rows are short. People who ask for the same test usually ask in the same year, often in the same thread.

How we found them

We pulled every post and comment through the forums’ public APIs. A cheap regex kept 28,018 sentences with an ask phrase, such as “I’d love to see”, “has anyone tried” or “someone should test”. Claude read each sentence with its neighbours and kept 5,819 concrete requests for an experiment, a measurement, a replication or a proof. It wrote each one as a one-line experiment.

To merge repeats, we embedded the one-line experiments and clustered them. Claude then split each cluster into groups that ask for the same experiment, on any model or in any year. We ranked the groups by the number of distinct askers, then by the years between the first and the last ask, then by karma. We fixed this rule before we saw any ranking¹.

For each of the top 50, a search agent looked for a paper or post that ran the asked test. It had to open the link. A test of a nearby question did not count.

The list

The open asks lean toward people and institutions: which arguments about extinction risk persuade which audiences, whether safety research speeds up capabilities, and whether AI safety talent programmes work. A few technical asks are open too, such as a probe for evaluation awareness that the model never puts in words, a working demo of gradient hacking, and a test of whether different learners find the same abstractions. The full list, with a link to every asker, is below.

Should you trust our results?

• Our regex only finds asks that use a known phrase. One skeptic read 150 snippets that Claude rejected and found 2 real asks (1.3%). It stopped before it checked the texts the regex skipped.
• Another skeptic read 100 random AI asks: 95 were real asks and 91 were real asks about AI. In the top 10, 26 of 36 asking texts asked for exactly their group’s experiment.
• “The same experiment” is Claude’s judgement. A looser grouping by topic gives bigger clusters (up to 33 accounts), but those mix different experiments.
• We count people by their display name, so one person with a LessWrong and an EA Forum account counts once. Two people with the same name would also count once.
• Each “answered” is one agent search of about five minutes. Some answers cover only part of the ask (ranks 8 and 32, for example), and a longer search could find tests we missed.
• 86% of the AI asks are from 2022 or later, so the early years carry little weight.
• Two skeptics checked this run, not three, and one stopped early on a provider error. Their notes are in the receipts.

So, do the experiments the alignment forums ask for most stay untested? No. Most of the tests that several people asked for were run, often within a year.

I find the short rows the most telling: people rarely ask for the same test twice, so a request that comes back is a strong signal. We added ten of the runnable asks to the Lab’s hit list, so the agent swarm can pick them up.
