Robin Hanson

Thanks for the explanation.

Speaking personally, I would much prefer that contributions judged to make an article net worse be reverted than downvoted, both because this gives the contributor much clearer feedback and because it improves the quality of the article, relative to the opinion of the user deciding whether to downvote or revert. If other users disagree with that assessment, the karma system can perhaps then be used to resolve the disagreement, or to at least contribute to a resolution by conveying a signal whose meaning is now much easier to discern.

Concerning the specific edit: on reflection, I agree with you that the information I included would have been more appropriate in the Overcoming Bias article, and I am inclined to agree with you that it is best omitted from Hanson's article. Accordingly, I have restored the previous version of the entry, though with the external link fixed.

I'm not sure how to interpret the downvoting of a recent edit I made. I simply clarified a sentence and replaced a dead link with the version archived by the Wayback Machine. Downvoting substantive posts without providing an explanation is often justified given the difficulty associated with pinpointing the nature of a complex disagreement, or because the signal the downvote is meant to convey is relatively clear from the context. But with a simple, atomic edit that seems unambiguously (very mildly) positive, at least from a commonsense perspective, such unexplained downvotes are apt to leave an editor puzzled and unable to draw any valuable lessons, except perhaps that they should simply abstain from contributing in the future.

Working in Virtual Reality: A Review

Related:

This week, I’ll spend 40–50 hours in Virtual Reality (Immersed), like I did last week and every (work) week for the last 2½ years. It’s not just fun and games — there are plenty of those, along with exercise, meditation, creativity, socializing, etc. — but for this article, I’m only focusing on (and counting) the work.
 

Yes, really: 8–10 hours a day strapped in. I’ve encountered a fair amount of skepticism about both the technology and the general premise, many nit-picks about the software, or how it fails to match some preconception about how things “should” work.

The Best Software For Every Need

I decided to switch to Emacs 1.5 years ago, and I feel it's the most important computing decision I made since... starting to use a computer? I may write a more detailed post on what things I use Emacs for, but here I just wanted to endorse the above recommendation, including its caveats ("Don't bother with it though if you don't have some time to invest in learning it"), and emphasize that Emacs can fulfill many needs besides "code editor" (I am not a programmer myself).

Anki decks by LW users

Thanks, but this post is no longer updated and the link is not broken on my website. (If you think that's confusing, despite the notice at the top, I may consider replacing its contents with just a link, though retaining the content may make it more discoverable.)

The Best Textbooks on Every Subject

Thanks for the update!

chaotic History of Economic Analysis

The word 'chaotic' was an adjective I chose to describe the book's content, rather than part of the book's title. :)

Real-Life Examples of Prediction Systems Interfering with the Real World (Predict-O-Matic Problems)

Related to the ReplicationMarkets example: on Metaculus, there is an entire category of self-resolving questions, where resolution is at least in part determined by how users predict the question will resolve. We have seen at least one instance of manipulation of such questions. And there is even a kind of meta-self-resolving question, asking users to predict what the sentiment of Metaculus users will be with regard to self-resolving questions.

AGI Predictions

The probability I would assign to #8 intuitively is about 0,41. Math based on my other three predictions yields (doing the calculation now) 0.476. I am going to predict the math output rather than my intuition.

I think the correct response to this realization is not to revise your final answer so as to make it consistent with the first three. It is to revise all four answers so that they are maximally intuitive, subject to the constraint that they be jointly consistent. Which answer comes last is just an artifact of the order of presentation, so it isn't a rational basis for privileging some answers over others.

2020 Election: Prediction Markets versus Polling/Modeling Assessment and Postmortem

The contracts are denominated in USD, and they pay in that currency. But you trade on margin, and the collateral can be in any currency (crypto or fiat). In your example, you get back the BTC plus 15% of what that BTC was worth in USD when you made the trade. 

Incidentally, TRUMPFEB is now trading at 0.16 (i.e. implied 16% chance that Trump is president next February). This looks insane to me (and I have bet accordingly). I'd be curious if you or others have further thoughts on what might be going on.
