What is tag­ging on LessWrong?

Tags al­low re­lated con­tent to be linked to­gether. The sys­tem is straight­for­ward:

  • Posts can be tagged with tags (ex­am­ple).

  • Tag pages provide the de­scrip­tion of con­cept the tag is about a and list of all posts tagged (ex­am­ple).

  • The Con­cepts page dis­plays all ex­ist­ing tags.

  • Tags ap­pear in search re­sults.

  • Tags can be used to filter the Lat­est Posts list on the Front­page, al­low­ing you to see more or less of posts with cer­tain tags.

  • You can vote on the rele­vance of a given tag to post, in­di­cat­ing “I think this tag shouldn’t ap­ply to this post” or “this post is a cen­tral ex­em­plar of this tag”.

    • Tech­ni­cally, ap­ply­ing a tag to post is up­vot­ing its rele­vance. Tag rele­vance de­ter­mines the de­fault sort or­der of posts on tag pages.

    • See the Tag Vot­ing sec­tion of this FAQ.

What is the point of tag­ging?

Philo­soph­i­cally, the tag­ging sys­tem is an at­tempt to give posts on LessWrong longevity. In con­trast to news and so­cial me­dia sites, where the main con­tent be­ing read is what was posted that week, we want users to read the best and most rele­vant con­tent to them – when­ever it was writ­ten.

Longevity and find­abil­ity of old con­tent also seems key to thinkers build­ing upon each other. If I want to con­tribute new knowl­edge, it helps to build on what was already said pre­vi­ously – to main­tain the con­ver­sa­tion – and for that, we want to keep track­ing of the “con­ver­sa­tion”. Tag­ging is an at­tempt to do that.

Tag­ging ac­com­plishes this through sim­ple means: it al­lows you to con­ve­niently find all the con­tent on a spe­cific topic. That can be done top-down from the Con­cepts page, or bot­tom-up from a tag on a posts page. Tags are also a quick way to learn the top­ics of a post if the ti­tle isn’t di­rect. Lastly, tags al­low users to filter the con­tent they are shown – get­ting more or less of cer­tain top­ics. And al­though we haven’t built it yet, it’s pos­si­ble we will build topic-spe­cific dis­cus­sion around tags.

Tag pages are similar to wiki pages. While we are still figur­ing this out, the tag­ging sys­tem may grow into a com­bined tag­ging-and-wiki sys­tem that pro­vides ex­pla­na­tions of key con­cepts used on LessWrong.

What are the Core Tags?

The LessWrong tag­ging sys­tem pos­sesses six core tags that at a high-level cap­ture the ma­jor top­ics of dis­cus­sion on the site. They hope­fully provide a good idea of what the site is about.

We aim to have these tags ap­plied ac­cu­rately and com­pre­hen­sively across all posts on the site, so that they will be use­ful as filters to boost or re­duce the pres­ence of con­tent on your feed.

Core tags also provide a nat­u­ral way to cateo­girze other tags on the site, e.g. on the Con­cepts page, though of­ten other tags don’t fall neatly into only one (or any) of the core tags.

The Core Tags are:

Full de­scrip­tions of each can be found on their re­spec­tive tag pages (click or hover). There are also some com­mon con­fu­sions ad­dressed in the next sec­tion.

I’m con­fused by the Core Tags. How are they differ­ent?

Ra­tion­al­ity vs AI

Both Ra­tion­al­ity and AI are about minds – that’s why AI is such a nat­u­ral fit on LessWrong– and this causes many ideas ap­ply­ing to AI to also ap­ply to Ra­tion­al­ity. Some posts and tag might le­gi­t­i­mately be­long to both, but a good heuris­tic is that Ra­tion­al­ity con­tent should be of in­ter­est to a reader even if they’re not in­ter­ested in the de­sign or en­g­ineer­ing of ar­tifi­cial in­tel­li­gences.

Ra­tion­al­ity vs Practical

Both of these ap­ply to top­ics that help peo­ple do bet­ter. The dis­tinc­tion is that we want the Ra­tion­al­ity tag to be more ex­clu­sively about do­ing bet­ter by think­ing bet­ter, in fancy words, by im­prov­ing your cog­ni­tive al­gorithms. Prac­ti­cal, in con­trast, is for all the ob­ject-level ways to do bet­ter, e.g. get­ting a good night’s sleep and tak­ing care of your health.

World Model­ing vs The Rest

Al­most all dis­cus­sions on LessWrong con­cern mod­els of the world, doesn’t this tag ap­ply to ev­ery­thing? Po­ten­tially, yes, but we wanted a name that ap­plied to top­ics pri­mar­ily driven by a broad cu­ri­os­ity about the world. Raw sci­ences and similar. “How does it work?” be­ing the fore­most ques­tion. Science might have been an al­ter­na­tive name, but many top­ics we wanted to in­clude top­ics aren’t im­plied by that, e.g. his­tory.

In a way, the other core tags could be con­sid­ered spe­cial­ized sub-tags of World Model­ing, and World Model­ing is the catch-all for the rest.

World Op­ti­miza­tion vs World Modeling

World Op­ti­miza­tion is the tag in­tended to cap­ture all dis­cus­sion of top­ics di­rectly rele­vant to try­ing to make the world a bet­ter place. That means dis­cus­sion of al­tru­is­tic causes, but also mod­els of things which are es­pe­cially rele­vant to chang­ing things, e.g. in­cen­tive struc­tures in large in­sti­tu­tions. Many so­cial mod­els have felt ap­pro­pri­ate in World Op­ti­miza­tion for that rea­son.

World Op­ti­miza­tion vs Practical

The differ­ence be­tween these two is largely scale. World Op­ti­miza­tion con­cerns how we make the world at large bet­ter, while Prac­ti­cal are top­ics rele­vant to in­di­vi­d­u­als try­ing to make their lo­cal situ­a­tion. “Altru­ism vs Self-Help” isn’t quite right, but points in the cor­rect di­rec­tion.

Who can tag?

At this time, all users can both ap­ply, cre­ate, and vote tags. Users can ap­ply tags to any post, not just their own. How­ever, all new tags and gen­eral tag­ging ac­tivity are re­viewed by the LessWrong team.

Who con­trols tag­ging?

Whether a post has a par­tic­u­lar tag is de­ter­mined by users vot­ing on a rele­vance score. Ap­ply­ing a tag to a post is the same as up­vot­ing its rele­vance to that post, re­mov­ing a tag is the same as down­vot­ing its rele­vance to that post, and the post has the tag if ev­ery­one’s votes sum to a pos­i­tive rele­vance score. The strength of your votes de­pends on your karma score, and is the same as the strength of your votes on posts and com­ments.

Un­like scores on posts and com­ments, the LessWrong team may oc­ca­sion­ally over­ride the vot­ing sys­tem, for ex­am­ple, when clar­ify­ing a tag’s mean­ing or split­ting a tag into two tags.

Any­one can sub­mit tags and edit tag de­scrip­tions, but the LessWrong team has the fi­nal say in which tags ex­ist and what their de­scrip­tions are. In the fu­ture, if tag­ging is used heav­ily, we may build other dis­pute re­s­olu­tion mechanisms.

The LessWrong team cur­rently has the fi­nal say in which tags are good vs not, which posts go in tags, etc. The team will make the fi­nal de­ci­sions in any dis­putes arise in re­la­tion to tag­ging.

In the fu­ture, the LessWrong core team might give au­thor­ity to mods or oth­ers in mak­ing de­ci­sions about tag­ging.

What are the se­cret fancy URL pa­ram­e­ters for link­ing to tags?

You may have no­ticed that tag ti­tles are of­ten dis­played alongside the post-count for that tag. You can make this hap­pen when you link to a post by ap­pend­ing the fol­low­ing to the url:

e.g. https://​​www.less­wrong.com/​​tag/​​ra­tio­nal­ity?showPost­sCount=true

Fur­ther, since tag names are of­ten changed, you can cause a tag link to also use the cur­rent name with the url pa­ram­e­ter:

e.g. https://​​www.less­wrong.com/​​tag/​​prac­ti­cal?useTagName=true­

In con­junc­tion, you have the url pa­ram­e­ters:


With those pa­ram­e­ters added to the url, your link will show post count and always use the lat­est tag name.

How can I help with tag­ging?

I’m so glad you asked. There is much to be done. A few ma­jor tasks help the tag­ging sys­tem flour­ish:

Ap­ply­ing Tags

Who can ap­ply tags?

Any­one can ap­ply tags to any posts.

I want to help tag, where’s a good place to start?

It’s good to start by be­com­ing fa­mil­iar with LessWrong’s ex­ist­ing tags. You can see them on the new Con­cepts page. Then are a cou­ple of tag­ging strate­gies:


  • You might no­tice the ab­sence of tags you think should ex­ist. Great! You can cre­ate that tag now and then be­gin adding rele­vant posts to it.

  • You might see a tag and be sur­prised at how few posts it has. Awe­some, you can add any miss­ing posts you know of to it from ei­ther the tag page or post page (see the next sec­tion).

  • Make sure all your fa­vorite posts are tagged.

  • Just tag whichever posts have come up on your From the Archives feed on the front­page.


  • Look at the list of high-karma posts here that don’t yet have tags [on­site, op­ti­mized spread­sheet]. See if they fit any ex­ist­ing ones, or whether we’re miss­ing a tag for a real cluster, then make it.

  • Alter­na­tively, we have an au­to­mat­i­cally up­dat­ing spread­sheet (ev­ery five min­utes) that tracks the tags on the most viewed posts ac­cord­ing to our data. Caus­ing those to have good tags is a high-lev­er­age due to the high traf­fic.

  • If you’re an au­thor, en­sure all your own posts are tagged.

You might find that you end up iter­at­ing be­tween the two ap­proaches.

How do I add tags?

On the post page

The “Add Tag” but­ton is lo­cated in the tags sec­tion at the top and/​or bot­tom of a post page.

On the tag page

At the bot­tom of the posts list on a tag page, there is an “Add Posts” but­ton.

How do I re­move a tag?

Un­der the hood, tags are im­ple­mented with a Tag Rele­vance vot­ing sys­tem. There­fore the purest way to re­move a tag is by down­vot­ing its rele­vance. On a post page, use the tag hover to up or down­vote the rele­vance. On a tag page, you will see the tag vote but­tons on the left side of the post item.

How­ever, for in­tu­itive­ness, the tag hover-over on post pages will dis­play a “Re­move Tag” but­ton when you have the abil­ity to re­move a tag, i.e., no one else has voted on its tag rele­vance.

If some­one else has also voted on the re­la­tion­ship be­tween a tag and a post, your only op­tion is to cast your vote. If your vot­ing power is greater than or equal to the cur­rent tag rele­vance, you can re­move the tag that way.

I’m tag­ging. How com­pre­hen­sive should I be?

The point of tag­ging is to link to­gether good re­lated con­tent. The point is not to tag ev­ery post with ev­ery tag that might con­ceiv­ably ap­ply to it.

Think of tag­ging as cre­at­ing a cu­rated list of ma­te­rial on a topic that some­one in­ter­ested in that topic would want to find. If a post touches on a topic but ex­tremely tan­gen­tially, it might not be worth tag­ging it. If a post is low qual­ity but tech­ni­cally dis­cusses a topic, it isn’t nec­es­sary to tag it ei­ther.

Don’t worry about it too much, but over­all you can use judg­ment about what gets tagged. Not ev­ery post should get tagged.

Should I be ap­ply­ing core tags to all posts?

Don’t worry about try­ing to ap­ply the core tags to old posts you en­counter. More spe­cific tags are gen­er­ally more use­ful. As we’re try­ing to fill-out the tag­ging sys­tem, it’s good to fo­cus on the more spe­cific con­cepts that ap­ply to posts.

Should I tag event posts?

Al­most never. The point of tag­ging is to sur­face rele­vant con­tent on a topic to cur­rent read­ers. Even if an event was themed, prob­a­bly that event an­nounce­ment isn’t use­ful to fu­ture read­ers.

Tag Voting

Why tag vot­ing?

While many posts might fall un­der a tag, a cou­ple of situ­a­tions fre­quently arise:

  1. Not all posts ap­ply equally. Some posts are cen­tral ex­am­ples of a tag that ex­tremely rele­vant, oth­ers only have pass­ing us­age of the tagged con­cept.

  2. Peo­ple dis­agree about which tags ap­ply to which posts.

LessWrong solves these with a tag rele­vance vot­ing sys­tem. It’s similar to karma, but it’s not karma. Users can vote on how rele­vant a tag is to a post with ei­ther small or strong votes (same as karma) and us­ing their usual vote strength, how­ever, this is still a sep­a­rate sys­tem.

The tag rele­vance scores are used for the de­fault sort­ing of posts on tag pages.

How to tag rele­vance vote?

On a post page

Hover over a tag to get its hover-pre­view. The card will have vote but­tons.

Tag vote but­tons are dis­played on the tag hover-pre­view. Th­ese can also be used to re­move a tag from a post, if the vote score be­comes zero or nega­tive.

On a tag page

On the left side of the post item where vote but­tons for tag rele­vance.

On tag pages, these vote but­tons are for a post’s tag rele­vance score (not karma)

Mak­ing Awe­some Tags

Who can cre­ate tags?

Any­one can cre­ate new tags!

We re­view all new tags, and will mod­ify/​delete tags which are du­pli­cates, don’t match the gen­eral con­ven­tions, or aren’t that good. Don’t let this hold you back! Take it as re­as­surance that you can cre­ate tags with ap­prox­i­mate im­punity.

When should I cre­ate a tag?

Many tags don’t ex­ist sim­ply be­cause no one got around to cre­at­ing them.

The pur­pose of tags is to help peo­ple find (or avoid) re­lated clusters of con­tent. When a cluster ex­ists but has no tag, then it’s ap­pro­pri­ate to cre­ate a tag for it.

Good tags need to strike a bal­ance be­tween ap­ply­ing to enough posts to be worth cre­at­ing, but not so many as to be use­less. For ex­am­ple, so many posts on LessWrong have re­duc­tion­ist mod­els that a re­duc­tion­is­tic mod­els tag would ap­ply to too many things. (By too many, I mean hun­dreds.)

A good heuris­tic is that tag ought to have three high-qual­ity posts, prefer­ably writ­ten by two or more au­thors.

  1. Tags are for col­lect­ing re­lated clusters of posts.

  2. A good tag should ap­ply to at least a few posts (~min­i­mum 3) but not too many (e.g. shouldn’t ap­ply to hun­dreds of LessWrong posts).

  3. Cau­tion should be used when cre­at­ing a tag that heav­ily over­laps with an ex­ist­ing tag. In such cases, mods or ex­pe­rienced tag­gers might weigh in how to best carve up con­cept-space.

What fur­ther wis­dom do you have, oh, wise tag-cre­ation-mas­ter?

A few good prin­ci­ples to keep in mind when cre­at­ing tags:

  • The tag­ging sys­tem is col­lec­tively ap­plied which limits its abil­ity to main­tain tags with high-de­grees of sub­jec­tive nu­ance.

  • Tags over­all ex­pe­rience pres­sure to be as in­clu­sive as pos­si­ble. If a con­cept is at all loosely con­nected to a topic, some­one will ap­ply it.

  • The gen­eral re­sult of the above is that a closely re­lated, al­though the­o­ret­i­cally dis­tinct, con­cepts will end up blurred and hav­ing heavy re­dun­dant post over­lap.

What does this mean for tag cre­ation?

If you’re cre­at­ing a tag, think about how oth­ers might broadly con­strue it. It’s good to write a clear de­scrip­tion of the in­tended con­cept, but even bet­ter to have a tag name that fully con­veys what you want the tag to be about. Gen­er­ally, don’t rely on peo­ple read­ing the de­scrip­tion if you can avoid it.

Are there tags which are not suit­able for LessWrong?

Kind of. As men­tioned el­se­where, much of the goal of the tag­ging sys­tem is to give the site con­tent longevity. That means it makes less sense to cre­ate tags of only tem­po­rary in­ter­est.

Semi-re­lat­edly, on LessWrong we try to min­i­mize dis­cus­sion of hot but­ton or ex­tremely poli­ti­cized top­ics. It’s not that they’re not ever im­por­tant, but cer­tain top­ics are at­trac­tors of bad con­ver­sa­tion on­line. Tags cre­ated for those top­ics may be re­jected even if LessWrong has posts re­lated to them.

What should I name my tag?

Names are one of the pri­mary ways that peo­ple find tags, so it’s im­por­tant to name a tag in a way that will be in­tu­itive to most peo­ple. What would most peo­ple search for? Affect might be the more tech­ni­cal term, but most peo­ple will prob­a­bly search for Emo­tions, mak­ing it a bet­ter tag name.

Fur­ther, many peo­ple will ap­ply a tag to posts with­out read­ing the de­scrip­tion or care­fully look­ing over the cur­rently tagged posts. This can eas­ily cause the tag to “drift” from its in­tended us­age. To pre­vent this, the tag name should try to be very ex­plicit about the cluster it’s point­ing to.

Many tags are best de­scribed by a name that is some­what over­loaded, e.g. Re­la­tion­ships. Here it is good to use Wikipe­dia style dis­am­bigua­tion, e.g. Re­la­tion­ships (In­ter­per­sonal) vs Re­la­tion­ships (Ro­man­tic). Put­ting the mod­ifier in the dis­am­bigua­tion af­ter the main word means peo­ple look for “R”, the first let­ter of the main word, still find it eas­ily.

  1. Name the tag in a way that will be in­tu­itive to most peo­ple for find­ing that con­cept.

  2. Have the tag name con­vey the pre­cise con­cept, don’t as­sume it will be ob­vi­ous to oth­ers.

  3. Use dis­am­bigua­tion where nec­es­sary, e.g. Ex­er­cise (Phys­i­cal), not just Ex­er­cise.

  4. Use ti­tle case: In­stru­men­tal Con­ver­gence, not In­stru­men­tal con­ver­gence.

  5. Use & and /​ where nec­es­sary. Th­ese are cleaner and save space over the word “and”

Note that as de­scribed here, you can mod­ify your tag links such that the cur­rent tag name is always used, even if the tag was re­named.

How do I write a good tag de­scrip­tion?

Tag de­scrip­tions define the cluster of posts the tag is sup­posed to col­lect. It’s im­por­tant for helping fu­ture tag­gers de­cide whether or not some­thing be­longs, and sets ex­pec­ta­tions of read­ers about what they’ll find.

Open­ing sentence

The open­ing sen­tence of a tag de­scrip­tion should in­clude the tag name or ap­prox­i­mately the tag name, bolded, in a way that defines the cluster, e.g.:

  • A bucket er­ror is when some­one mis­tak­enly lumps to­gether mul­ti­ple con­cepts that are in fact dis­tinct and can vary in­de­pen­dently. It is a fal­lacy of com­pres­sion.

If a con­cept is likely to have mul­ti­ple search terms, it is good to put these in the de­scrip­tion. This will cause them to be found via search even if the pri­mary tag name is differ­ent. This is a solu­tion when mul­ti­ple tag names seem ap­pro­pri­ate.

Re­lated Tags /​ See also

Peo­ple in­ter­ested in one tag are of­ten also in­ter­ested in “neigh­bor­ing” tags. More­over, peo­ple search­ing for a par­tic­u­lar con­cept will of­ten first hit upon a re­lated con­cept. For this rea­son, it is im­por­tant for all tags to in­clude links to other tags in nearby con­cept space. This is ac­com­plished with a See Also sec­tion.

For ex­am­ple, the tag for Pro­duc­tivity should con­tain a See Also sec­tion that links to the tags for Akara­sia, Willpower, Mo­ti­va­tions, and Prac­ti­cal. Prac­ti­cal is roughly the “par­ent” tag for Pro­duc­tivity and should be in­cluded too.

It’s bonus good to use the tag link pa­ram­e­ters when link­ing to other tags in a de­scrip­tion. This en­sures the lat­est tag name is always used.


Feel free to be more ex­per­i­men­tal with your tone and em­pha­sis than you would have to be on places like Wikipe­dia. We are not writ­ing for an au­di­ence that is as broad, and we are less con­strained to keep ev­ery­thing re­ally defen­si­ble, so you can err on the side of writ­ing things the way you would say it. How­ever, it’s also fine to stick with an en­cy­clo­pe­dic tone if the muse doesn’t strike you.

[Op­tional] Examples

For many, but not all, tags it is use­ful to provide ex­am­ples of the con­cept in the de­scrip­tion. For ex­am­ple, the tag for Gears-Level Un­der­stand­ing lists a few ex­am­ples of such ex­am­ples. [Even bet­ter is to also list some counter-ex­am­ples.]

[Op­tional] In­tro­duc­tory Con­tent, Se­quences, and Ex­ter­nal Resources

It can be good to have a sec­tion in a tag de­scrip­tion point­ing out the best in­tro­duc­tory or defin­ing ma­te­rial for a con­cept. E.g., the con­cept of Slack was in­tro­duced in the post of the same name.

Also, it is not cur­rently pos­si­ble to tag Se­quences or ex­ter­nal links, so if some of those are rele­vant to a tag, it is good to in­clude them un­der a Re­sources sec­tion.

Gen­er­ally, the list of tags can’t provide con­text on the posts, and the tag de­scrip­tion area is an op­por­tu­nity to do that. Not re­quired, but good.

[Op­tional] Quotes

A good quote can spice up a tag de­scrip­tion. In­clud­ing this af­ter the open­ing para­graph is a good way to go.

  1. The open­ing sen­tence should use the bolded tag name (ap­prox­i­mately) to define the con­cept.

  2. In­clude a list of “neigh­bor­ing” tags in a See Also sec­tion.

  3. Ex­am­ples are good when defin­ing a con­cept (in­clud­ing nega­tive ex­am­ples).

  4. Con­sider high­light­ing or link­ing to key re­sources for the con­cept, es­pe­cially Se­quences and ex­ter­nal re­sources that can’t be tagged.


How can I edit tags?

Tag de­scrip­tions can be ed­ited af­ter the fact, not just at the time of cre­ation. Every tag page will have an “Edit Wiki” but­ton be­neath the ti­tle (alongside a His­tory but­ton that lets you see all post ed­its).

How can I find tags in need of im­prove­ment?

Not ev­ery tag starts life as a Fully-Op­ti­mal-Ul­tra-Tag. Kind and gen­er­ous users can find these fixer-up­per tags and help them re­al­ize their po­ten­tial and/​or fi­nal form. You can sys­tem­at­i­cally find such tags by:

  1. Look­ing through the Tag De­tails sec­tion of the Con­cepts page and not­ing where tags are miss­ing de­scrip­tions of have few posts. (The sec­tion is sorted in de­scend­ing or­der of post count.)

  2. [COMING SOON} Use the Tags Spread­sheet to view tags sorted by Tag Grade. Look for tags you think you can cause to move up a grade or two, es­pe­cially Stubs.

If you’re about to em­bark on a tag-de­scrip­tion-im­prov­ing mis­sion, be sure to check out guidelines for good tag de­scrip­tions.

You can dis­cuss any tags you’ve been work­ing on at the Tags Dis­cus­sion/​Talk Thread.

Th­ese tags are ba­si­cally the same/​there are ac­tu­ally two tags here. What do I do?

In the long-term, we ex­pect there to be many in­stances of tags need­ing to be merged or split. The LessWrong dev team hasn’t yet built the tools for that, but if you mes­sage us (In­ter­com, etc.), we’ll sort it out.

I want to dis­cuss a tag. How do I do that?

The dev team is cur­rently work­ing on Talk Pages for tags where their de­scrip­tion and con­tent can be dis­cussed. Un­til that has shipped, please use the Tags Dis­cus­sion/​Talk Thread.

Boba and I are fight­ing over this tag, what do we do?

The LessWrong team will help sort out what should ac­tu­ally be done with the tag. Feel free to call on us in the Tags Dis­cus­sion Thread or ping us on In­ter­com.

What is a tag’s qual­ity grade?

To aid in tag­ging work, we have made a tag grad­ing sys­tem. Tags can be clas­sified as A-Class, B-Class, C-Class, Stub, or Flagged. See the full crite­ria for each grade here.

Note: only tag­ging mod­er­a­tors may change the grade of a tag. If you be­lieve a tag should have a differ­ent grade, please say on the tag’s Talk page [com­ing soon] or the Tags Dis­cus­sion/​Talk Thread. We may change this once the sys­tem is more es­tab­lished.

All tags start out with a de­fault grade of Stub. Usu­ally, the mods will no­tice quickly if a tag is more than a stub, but you can ping us if you think we’ve missed some­thing.

Where can I see a tag’s grade/​class?

  • The grade is visi­ble on the tag page be­neath the tag’s ti­tle.

  • Grade be used as a filter in the Tag De­tails sec­tion of the Con­cepts page.

  • A list of all tags with their grades can be viewed in the Tags Spread­sheet.
