I have confirmed that the article is taken from WhatIs.com and that the date sequence is such that we need to start over from scratch. There is a lot of scholarship on the subject and I have confidence that the community can get this article back in shape in no time; however, please be mindful of others' intellectual property rights. Sorry for the inconvenience, but that is how it goes sometimes.--BradPatrick 19:24, 20 June 2006 (UTC)

Couldn't be bothered to fix it yourself, though, eh? Easier to bitch about (possible) copyright infringement than to actually do something constructive. Typical behavior from the Wiki types: Lots of interest in red tape and voting and silly arbitrations, but not much effort spent actually building an encyclopedia.

This page looks very similar to http://whatis.techtarget.com/definition/0,,sid9_gci932596,00.html, which is copyright protected. Is this a copyright issue or - as I hope - not? --badpazzword [registered user but not logged in]

Shouldn't there be references to Lost here? It does seem to explore the fact that everyone on the Island is connected.- JustPhil 13:48, 4 October 2006 (UTC)

You are absolutely right, everybody seems to be connected - that is actually the premise of the show. But before you mention that here, remember what your touching points between SDOS and Lost are: "connectedness" and.... mhhmm.. that's it. so, for example you could talk about the royal families of europe, or any other group with much "connectedness", and the relevance to this article would be the same: NONE.-- ExpImptalkcon 21:35, 30 October 2006 (UTC)

What about this lost: www.lost.eu/41994 It is very much based on 6 degrees.

practical applications of the theory

The 'six degrees of separation' theory has been practically applied in research as well as problems such as HIV infection among hard to reach populations. You can read about one such application in the Cornell University website http://respondentdrivensampling.org

Another practical application is that you can link George W Bush to any problem in the world, large or small, with at most six connections —The preceding unsigned comment was added by 68.121.245.155 (talk) 04:31, 5 December 2006 (UTC).

Wikipedia game

I agree that it doesn't belong in the article, but I put in a link to the page regarding the game on the See Also section. This is because I personally came to the article looking for a reference to the game, so I feel like you need to have a reference to it somewhere. Feel free to share your opinion if you disagree.--CountCrazy007 19:24, 17 December 2006 (UTC)

Updated description

The very lean description on this site attributed the term Six Degrees of Separation to Stanley Milgram, which is incorrect. I've updated the description with more accurate and fleshier background. -ShashankTripathi 10:16, 16 Mar 2005 (UTC)

What about the movie "6 Degrees of Separation" with Will Smith?

Shouldn't "a chain of acquaintances that has no more than four intermediaries." actually say FIVE intermediaries? --216.58.0.55 15:12, 27 April 2006 (UTC)

You're right about the five intermediaries. Six degrees equals five intermediaries. However, the major problem with the current Wikipedia definition of the small world / six degrees of separation theory -- besides the fact that it has clearly been plagiarized from another website, which is bad enough -- is that it completely misinterprets and misstates the theory, missing the point entirely. The theory does NOT state that every person can be connected to every other person by an AVERAGE of six degrees (i.e. through -- on average -- five intermediary acquaintances). This would be fairly unremarkable and not particularly interesting, if you thing about it for a minute. What it states (and this is the essential and controversial point) is that every person can be connected to every other person by a MAXIMUM of six degrees (i.e. through NO MORE THAN five intermediary acquaintances). I'm surprised that this isn't what people are discussing on this talk page. 65.95.126.24 14:50, 2 May 2007 (UTC) Michael Graves 65.95.126.24 14:50, 2 May 2007 (UTC)

The Theoretical Basis?

The theoretical basis seems to make sense but its wording is flawed. It makes the claim that if everyone knew 42 people then 6 billion people could be joined by 6 degrees of separation but it doesn't take into account the idea that person A may know 42 people, one of them beign person B. Person B may know 42 people but for the maths do work correctly person B would have to know 42 people that person A doesn't know. The theoretical basis is mathematically fine but maybe it should be rephrased somehow. I'll do it myself soon if there's no objections. —Preceding unsigned comment added by 211.28.154.175 (talk) 08:03, 2 September 2007 (UTC)

It needs to be stressed that the calculation suggesting that 42 acquaintances per person are required is grossly over-simplified and represents an extreme theoretical minimum. The main problem, as already suggested, is that every person in the network of connections would need to know 42 people unconnected with any of the people at the same of fewer degrees from the starting person, but this is far from a small issue. I can't think of a single one of my friends who is not familiar with at least a few of the others, and I've discovered enough unexpected mutual acquaintances (the last discovery, coincidentally, being only yesterday) to convince me that plenty more remain to be found. The likelihood of duplicated connections should become exponentially higher with every additional degree of separation, resulting in a very much smaller final population.

The last step of the 42^6 calculation suggests that the 131 million people at 5 degrees of separation will know between them some 5.5 billion people each known to none of the others, ie the remaining population of the world!

Clearly the number of people we each need to know is much higher that 42 if we are to reach the global population within 6 degrees, and a considerably more sophisticated formula is needed to even approximate that number. -- Dr Walpurgis 04:22, 16 September 2007 (UTC)

Original research in "Theoretical basis" section

As mentioned above, the theoretical basis section is seriously flawed, since it assumes that no one has overlapping groups of acquaintances. More importantly, though, it looks like original research, since it doesn't cite any source. I've added a maintenance tag for now, but I suggest deleting the whole section, since it doesn't really add value to the article; if we just fix it so that the math makes sense, it will still be original research. David 12:53, 6 October 2007 (UTC)

I support all of the above, but would go further - the "theoretical basis" is far from sound and requires at least two unlikely assumptions (each subsequent acquaintance is unique - not a reasonable mathematical model; no geographical implications - an unrealistic view of society). I think the presence of such a "proof" on wikipedia will leave non-experts with great and unfounded confidence in the six degrees principle (and probably leave them counting their friends to see if they can prove it by making more than 42(!)). Added to this, it was added in one edit, by a user account that only ever made that one edit, and there's no evidence that anyone other than that individual supports the model. In light of this, I'm going to take the perhaps controversial step of deleting it before the confusion spreads any further (people treat wikipedia as authoritative these days, not least in proving/disproving urban myths and so on). To wind people up futher, if necessary, I question the claim that the six steps need only be a mean - Karinthy's apparently original formulation seems to state (in that case five) as an upper bound, and made a bet that no-one could find an exception. Well it is wiki after all, if I'm wrong, you can always undo it. Behind The Wall Of Sleep 10:21, 8 October 2007 (UTC)'s largest and most controversial edit to date.
OK I just noticed that the averaging model was introduced by Milgram, so I retract the last bit about mean vs upper bound. I still think the theoretical basis was duff though! Behind The Wall Of Sleep 10:24, 8 October 2007 (UTC)
Agree: I agree with the removal. I think that the original edit was well-intentioned, but it detracts from the rest of the article. David 23:51, 8 October 2007 (UTC)
Just to add that I also think that the original edit was well intentioned - the author clearly put time and effort into it. My concern with the single-edit nature of it is the lack of review. "Duff" was probably an unnecessarily harsh choice of word on my part. Behind The Wall Of Sleep 16:01, 9 October 2007 (UTC)

The article Jewish geography necessarily is a rather short article, because once you've described the game, there isn't a whole lot more to say. It would fit here in the popularization section with the Kevin Bacon et al games, and I can't see any reason why it should be an exception to all the games which are incorporated into this article. Thoughts? - Revolving Bugbear 22:43, 20 November 2007 (UTC)

Upon a closer look I've noticed that a lot of the popularization sections have daughter articles. However, the point remains that Jewish geography is short and would fit there amongst them; it would hardly be worth doing in summary style, I think. - Revolving Bugbear 23:15, 20 November 2007 (UTC)

Balance

I know this is an attractive idea, but it's not universally recognised as scientifically sound, and certainly not mathematically proven. So, in the name of avoiding Wikipedia becoming a device for propagating potential urban myths I have added a couple of detractors' articles in the introduction. I feel this needs to be incorporated near the top of the article, as otherwise it takes a pro-six-degrees PoV. Many of the more ambitious formulations of the six-degrees claim (for example, that six links is a mathematically proven upper bound; that all the letters made it to their targets all around the world; that any human on earth can be reached) seem to be propagating wildly in folklore and wikipedia is first port of call these days to check these things. Good place to put it? Or would a "criticism"/"detractors" type section be better? Behind The Wall Of Sleep 11:25, 23 October 2007 (UTC)

THegeebus says: —Preceding unsigned comment added by Thegeebus (talkcontribs) 02:45, 26 February 2008 (UTC)

I changed this sentence:

Detractors argue that Milgram's experiment did not demonstrate such a link,[1] and the "six degrees" claim has been decried as an "academic urban myth".[2]

to this:

Detractors argue that Milgram's experiment did not demonstrate such a link.[3]

Because the second half of that sentence is misleading.

Whether or not the global community has six degrees of separation is less important than the fact that it is a Small-world network. In other words, it may noy be 6, but it is some relatively small number and that is the key point. By calling it an urban myth, you are calling into question the whole science of scale-free networks. In his book Six Degrees, Duncan J. Watts explains the major flaws with Milgram's experiment. So I have no problem with the first part of your sentence, but to call the whole science an urban myth (which is what it sounds like you are calling it whether or not that is intended) is incorrect.

"Abstract Example"

The abstract example looks like a rewritten version of the "Theoretical Basis" that was previously deleted. It seems to make the same assumptions and, in my opinion, isn't easily understandable. I think it should probably be deleted but I don't trust myself to do that at the moment so I'll leave this comment here. If there are no objections, forever hold your peace.

Dangles1989 (talk) 13:35, 20 May 2008 (UTC)Dangles

Yes, I think the theory has most of the same flaws. The Pnnnnn etc model presented assumes connectedness is absolutely uniform globally; the conclusion about knowing 250 people assumes that these connections are to 250 groups each mutually isolated, and that the same property holds for the onward connections. I realise the contributor has caveated this by describing it as an "abstract example" but I have to say it's so abstract it would be hard to draw a useful conclusion from it. I think it will cause significantly more confusion than it will benefit - as for the erstwhile "theoretical basis" people will go counting their acquaintances and if they reach 250, will consider the six degrees principle "mathematically proven" for the whole world, which it clearly isn't. Also as before, it seems to be original research (and unlikely to be sourced). So I'm going to be bold and delete it! The author is of course invited to revert if we've got it wrong. Behind The Wall Of Sleep (talk) 15:19, 20 May 2008 (UTC)

I added the Abstract Example (just a simple construction from graph theory, not Research) because the idea of the average individual connectivity required to give an expected value of six degrees of seperation was not addressed. The assertion that this value is 43 (the sixth root of the population of the Earth) is based on a tree construction and so the expected seperation in this model is very nearly 12 -- that's pretty far from 6. 43 is easily seen to be incorrect. Maybe the previously deleted "Theoretical Basis" addressed this question properly. In my construction each Pnnnnnn represented a single person who knew 250 others single people. It is unrealistic to imagine that every person on the planet is just like every other person with respect to connectivity. But my little example does give the readers a ballpark ideal of what is required for the six-degree conjecture to be true. <wrStark@yahoo.com> —Preceding unsigned comment added by Wrstark (talkcontribs) 05:53, 21 May 2008 (UTC)

Why do people still do this? It sounds retarded. i bet some idiot added she because it was previously just he. IT'S THEY, GET IT RIGHT PLEASE.

Do not be discourteous - and "he or she" or "s/he" etc are "existing variants" (depending upon context).

There are likely to be few links between persons living on island in the middle of the Pacific Ocean and in a village in the Eurasian Steppe) - the concept may be valid, but it has been turned into an apt phrase that summarises the concept.

Mathematics (What is the value of Beta?)

The following is currently in the mathematics section:

"Mathematicians use an analogous notion of collaboration distance:[18] two persons are linked if they are coauthors of an article. The collaboration distance with mathematician Paul Erdős is called the Erdős number. Erdős-Bacon numbers are a further extension of the same thinking. Watts and Strogatz showed that: Average Path Length = (ln N / ln K) where N = total nodes and K = acquaintances per node. Thus if N = 300,000,000 (90% US pop.) and K = 30 then Degrees of Separation = 19.5 / 3.4 = 5.7 and if N = 6,000,000,000 (90% World pop.) and K = 30 then Degrees of Separation = 22.5 / 3.4 = 6.6. (Assume 10% of population is too young to participate.)" http://en.wikipedia.org/wiki/Six_degrees_of_separation#Mathematics

It is my understanding that this result was obtained using the Watts and Strogatz model http://en.wikipedia.org/wiki/Watts_and_Strogatz_model#Algorithm

Which is an interpolation between a regular ring lattice and an Erdős–Rényi model http://en.wikipedia.org/wiki/Erd%C5%91s%E2%80%93R%C3%A9nyi_model

The missing parameter in the above quote is the parameter beta which is the probability of an an edge being changed from that of a regular ring lattice. My question is what value of Betta did Watts and Strogatz choose and did they choose it empirical based on real world measurements of clustering coefficients. —Preceding unsigned comment added by S243a (talkcontribs) 21:18, 4 July 2009 (UTC)

Opinion bit removed

"But the numbers remain tricky. Actually it is a very simple fact. What is said elsewhere on the web will keep this mysterious. Our planet is about 6 billion people. Now in all the examples, the people given know only six people. But an average human being knows much more than just 6 people. 6 degrees of separation is just an average: it can go further than just six steps, and the number of people attached by one step is very big so 6 is just an average. Secondly, it's a question of time you can be many steps away from someone but will get closer to them if someone tells you that they know them. Ex : I am 3 steps away from R&B singer LiL Wayne. My friend's cousin met him at a concert. Think about it and deduct how this subject doesn't need all that thinking. I myself spent many hours thinking and calculating, but here i gave you the smart and very easy explanation on this subject. If you are convinced with what i say, then the rest of this page is useless repeat of the same tricky information. "

32 Generations?

Can someone provide a citation for this ridiculous-looking assertion?

I could believe it of a European population, perhaps. But 1200 years for any two humans is utterly absurd, and contradicts the claims at Most recent common ancestor. That article does claim that the MCRA for modern Europeans lived in 1000 AD, which might be the source for this ridiculous 32 generations bit. --Saforrest 15:08, 11 January 2006 (UTC)

The genealogy assertion is patently untrue, as there are populations which have been isolated for much more than 32 generations (and which, even if "discovered" and bred-into within recent years, still contain many members whose common-ancestry-with-all-humanity must be traced back to before the original settlement of their regions (think South Pacific islands, for example). Thirty-two generations is MUCH less than 1200 years (that time span would require an AVERAGE parental age of 37 at the birth of each child!). Spark240 (talk) 19:27, 18 January 2010 (UTC)

What counts as a link?

How closely do you have to be connected to someone to count as a link for working out the degrees of separation? Is it enough to have met the person once, even if they probably won't remember who you are, or do you have to be in contact with them? —Preceding unsigned comment added by Standoor (talkcontribs) 10:40, 5 August 2008 (UTC)

That is a good question. If really just knowing someone regardless of them knowing you counts then we are certainly connected and even the most secluded tribe living in some isolated area would know or one of their members would have at least seen another person outside their group, maybe someone they traded with from a neighbouring tribe who in turn may be more exposed to the outside world. —Preceding unsigned comment added by 188.221.140.173 (talk) 13:44, 18 May 2010 (UTC)

New data

New data from an article on BBC here leaning towards 3.74 degrees of separation. Yosef1987 (talk) 23:37, 22 November 2011 (UTC)

Be sure to be really straight forward

Since these are concepts that are "unbelievable" until accepted, we need to make very straightforward conclusions in this article. For example, "Anyone can connect to any person in the world through an average maximum of six mediaries, or, including both you and he, 8 people." Because my wife and I read this and neither of us knew whether the combined total was 6, 7, or 8 people. Second, under genealogy, "So if you can trace your genealogy back on all lines for 32 generations, you have a large enough tree to include a common ancestor with every single person on Earth, including those in extremely remote areas." Anyway, part of my point is the phraseology is a bit abstracted, and part of my point is it's hard to tell when it's referring to 6 generations including you or 6 generations removed from you. I suspect "six degrees" is the latter, and genealogy uses the former; and that may be a problem.

(responding to above unsigned undated comment) One person, all alone = no "separation." "One degree of separation" between two people = NO intermediaries, total of two people involved. Six degrees of separation = five intermediaries, total of seven people involved. Spark240 (talk) 19:25, 18 January 2010 (UTC)

Newton's laws of gravity were unaccepted initially. As was the theories of general and special relativity. As special relativity is still out for jury deliberations on some items, yet is asserted as fact in general articles on the topic, why should this article be an exception? For 6 degrees of separation for geneology to be accomplished would require a small and isolated population, hence its removal as fringe and nonsense theory. But in LIFELONG interaction, it's repeatedly been proved. Before international air traffic and even with the internet. Counterintuitive, yes, true, it appears so, as quite a few laws of physics are.24.127.137.154 (talk) 03:43, 26 January 2012 (UTC)

Origin of 6 degrees?

The article on Stanley Milgram suggests that his small-world experiment was the source of the "6 degrees of separation" theory. This article suggests that the theory was proposed earlier, in the 20's. Can anyone clarify?

I believe this is flawed. I read about s/1 actually talking about being connected even to eskimos and jungle tribes. hello? It could possibly be the case, that in todays(2006) world, everybody having internet access, has 6DOS to everyone else with internet access. but never ever could you include the people in rural or even remote regions like the amazon or central australia. And in the 20s, that's just bullshit eurocentrism. Any port worker in Boston is connected to any merchant banker in Shanghai(both being port towns) ? In the 20s? Give me a break.-- ExpImptalkcon 21:41, 30 October 2006 (UTC)
The objection is due to a failure of imagination. The contact may not be internet connected, indeed, the contact may well be a contact of 4 other contacts in a chain, unknown to the first contact by 3, who knows the final "amazon or central australia", even IF they had to WALK 100 miles to send a message (or send a messenger). Old knowledge isn't BS knowledge, only differently worded, yet being accepted frequently in modern contexts. OR we could dismiss older techniques, such as maggot debridment of non-healing wounds and accept fatalities and reject innoculation of C.Diff infected patients by family members stools and let those patients die. Along with a half dozen other ancient techniques that are being pulled off of the shelf and dusted off. Frankly, if it works, I stick with it, not reject it as counterintuitive.24.127.137.154 (talk) 03:49, 26 January 2012 (UTC)

Actually I don´t think it´s fixed, because as far as I know, 6 is the maximum separation between any two people (it´s a conjecture of course). What does average even mean? Someone with more knowledge on the subject should fix it. --129.49.21.151 (talk) 07:34, 1 November 2012 (UTC)

I think we are okay, so I am removing the box at the beginning of the article. There is a conjecture that the maximum is six. That is now in the intro of the article, so that is okay. Now, reality is not as simple as conjectures. For example, the maximum may be greater than six in reality, with an average around six. That's in the article too.

Social Computing Group Project: Problems and Improvements for Six Degrees of Separation Article

Group Member: Ran Ding, Mo Chen and Jiaruixue Wang

Identification of Problems:

1. Catalog/Section Lacks of Clear Boundary (Ran and Mo)

The boundary between several sections in this article is not clear defined. As Ran and Mo found, several items can be classified either in Popularization or Six degrees on the Internet, since those applications would be treated as signal of popularization, or they could be seen as practices of Six degrees of separation theory on Internet. Such Ambiguity may cause confusion for reader and editors.

2. Simliar Catalog (Mo)

The section "In popular culture" is talking about same thing as the part "Popularization". And we can see the "Popularization" mainly provides an outline about how "six degrees" infects popular culture. However, the part "In popular culture" provides a list of cultural things that are created with the idea "six degrees". In this point of view, it is also talking about how "six degrees" influences the popular culture. So I think they should be written in the same catalog.

3. Reference and Broken Links (Ran, Mo and Jiaruixue)

Several references's links are missing or unavailable. And they need reconnection or replacement if original source is removed.

Identified Missing Reference: 2,17, 30

4. Need More Explanation and Casual Link to This Topic (Mo and Jiaruixue)

Several parts, like "Popularization" and "Six degrees on the Internet", are too short to contain more details. Adding reference and casual connection will improve the overall quality of this article.

Discussion:

1.Section/Classification

Ran: I believe there's lack of a clear boundary between research project and games based on six degree of separation. For instance, Find Satoshi and Kevin Bacon game are similar items, but one is defined as Research while another is on Popularization. And there should be a clear boundary between academic research and practical application/games based on Six degrees of separation.Dd-556 (talk) 05:00, 12 November 2014 (UTC)

Mo: The part of "Six degrees on the Internet" is just talking about how the "six degree" is proved by some SNS and how popular it is on the Internet. It has some overlaps with the part "Popularization", and it also give some evidence that "six degree" can be proved through the Internet. So just classify them in the sort of "Six degrees on the Internet" is insufficient.Chenmo624 (talk) 18:34, 12 November 2014 (UTC)

Ran: I agree with your opinion, I checked those sections and found it is not quiet easy for following editors to define whether a new practice of Six degrees should be classified in popularization or Six degrees on Internet. And I'll post it as a main problem on the first part. Dd-556 (talk) 18:48, 12 November 2014 (UTC)

Jiaruixue: Mo's idea is good, but I disagree with that. Maybe, there is a little overlaps between the part "Popularization" and "six degree", it will be more confusing to put them together. Rachel wjrx (talk) 23:17, 12 November 2014 (UTC)

2. The layout of Shrinking World

Ran: And as one of above discussions, someone suggested that the origin of Six degrees of separation is not quiet clear in this article. Basically, I agreed with the idea that Six degrees of separation theory is not necessary associated with the invention of Internet. However, if one wants points out the 20s idea/theory is the true origin of Six degrees, then there should be some solid evidences rather than a sole author's work, but a research can be discussed and examined by multiple scholars.Dd-556 (talk) 13:30, 12 November 2014 (UTC)

Mo:I think the conception of "shrinking world" in this article is clear enough as a fundamental introduction to "six degrees". Personally, I think this article is mainly about "six degree", so it doesn't use too much detail about the evidences. The main point should be a guid to the "six degree".Chenmo624 (talk) 21:45, 12 November 2014 (UTC)

Ran: I think I missed a important point of this article, yes, it's just a introudction of this topic, so too much detail is not a wise idea.Dd-556 (talk) 22:01, 12 November 2014 (UTC)

3. Missing Reference and Broken Link

Ran: Even though this is a developing article, every reference article in Six degrees should be either created on Wikipedia or just listed as a term. For example, Contacts and Influences on the small world sub-title was marked as a reference article, but it is not created on Wikipedia. Therefore, I think it is good to remove its marker (just keep the reference source), or complete the reference article on Wikipedia are good solutions. And there are dual reference markers made on the same target (Contacts and Influences). Dd-556 (talk) 16:26, 12 November 2014 (UTC)

Mo: I think it is important to make sure that every reference is accurate. So make sure that every link is available is necessary.Chenmo624 (talk) 22:21, 12 November 2014 (UTC)

Ran: In the Research section, it stated that some human groups might not prove Six degrees of separation's link. And I think this is a very good point to make this article more objective by presenting difference views and facts, if there can be a sub-title in this section listed one of such experiment that demonstrate Six degrees theory has its limitation in those human groups. And Reference 17 is unavailable, needs a similar replacement. Dd-556 (talk) 16:41, 12 November 2014 (UTC)

Mo: In the reference section, the Reference 2 has an invalidate link on the author's name " Barabási, Albert-László ". Chenmo624 (talk) 22:30, 12 November 2014 (UTC)

Jiaruixue: In the reference section, the Reference 30 is linked to a blank page. Rachel wjrx (talk) 22:57, 12 November 2014 (UTC)

4. Need More Explanation and Casual Link to This Topic

MO: I think the subsection "Six Degree Of Der Kommissar" in the part "Popularization" isn't so relative to the "six degree". In this section, it only talks about a song that was rerecorded and rewritten by six singers. May be it tries to tell people that the fact this six people are connected through this way, however, it is unable to explain "six degree" in this case for the relationships between these people are all based on this song and people themselves are unknown to each other. Chenmo624 (talk) 19:15, 12 November 2014 (UTC)

Ran: Behind this story, I believe the author wants to use this example to illustrate that 'small world experiment' is widely existed in everywhere, as a single song can connect various bands in different ages. So it does explain the idea of six degrees of separation.Dd-556 (talk) 22:27, 12 November 2014 (UTC)

Jiaruixue: In the "Six degrees on the Internet" part, the "LinkedIn" and "SixDegrees.com" section are lack of details. It seems that the introduction of those two sections are similar. When I read those contents, I really suggest that more details can be added so that I can know what those part mean, how can they be related to "six degree". Rachel wjrx (talk) 22:36, 12 November 2014 (UTC)

Ran: I agree with Jiaruixue, if there's more detail given in this part. It will help readers better understand how Social Network using Six Degrees of Separation.Dd-556 (talk) 22:49, 12 November 2014 (UTC)

Potential Improvement:

1. Define a clear boundary and eliminate Ambiguity terms of those section titles (Done). Relocated the chapter of Six Degree on Internet into Popularization.

2. Combine the two catalog into one catalog (Done)

3. Adding the following replacement reference title (Done with Other Attributors' Help):

Ref 2: The writer's page on wikipedia is: https://en.wikipedia.org/wiki/Albert-L%C3%A1szl%C3%B3_Barab%C3%A1si

Ref 17: The Uncontacted Indians of Brazil: http://www.survivalinternational.org/tribes/uncontacted-brazil

Ref 30: Kevin Bacon Launches "SixDegrees.org" Charitable Initiative With Celebrity Friends to Encourage Giving:http://www.networkforgood.org/about/press/pressreleases/2007/01-18.aspx

4.The solution of the problem is to search more materials and extract related details to add to the content.

Work Plan:

Ran: I'll work on the section problems and reference links for this topic.

Jiaruixue: I am responsible to eliminate the broken link I found and I will also add some details to the "Linkedln" and "SixDegrees.com".

Mo: I will work on making the section distinguishable and make particular content more relative to the main topic".

A Strange Name

I have checked this in a couple of places, and this is what I have found, that the number 6 pertains to the number of other persons, so the total persons in the chain would be 7, including oneself - and the number of links would be 6. However, it is very strange that it is said to be "separation". For one does not consider someone's spouse to be "separated by one degree", though he or she would be, if I understand correctly. In other words, it should be called "5 degrees of separation", because you are, obviously, connected to one of those people, but the rest you are not.

Or perhaps the name should be "6 links at maximum, a universal connectedness".

It's completely bizarre that 0 degrees of separation would be only yourself. Surely I'm not the first to notice how absurd it sounds. Surely you are not "separated" from someone with whom you hold hands - but you would be separated by 1 degree, it appears... And then there's the curious case of conjoined twins, who are also, according to the phrasing, separated by 1 degree...

Facebook: 4.57 degrees (steps), not 3.57

§ Facebook claims there are 3.57 degrees of separation; however the source for this claim incorrectly(?) uses "degrees" as "number of intermediaries", so the actual value would be 4.57 to be consistent with the original definition where a degree is a "step" or relationship rather than an intermediary.

In order to properly edit that section, the other three figures (5.73, 5.28, 4.74) should be changed accordingly, but being careful not to make the same mistake and add 1 incorrectly, so I'm not sure I should just go and do it myself. Specifically the source I cited seems to claim that this also applies to that 4.74.

(All this is assuming "six degrees" means "five intermediaries" and not six, which is what Karinthy's quote seems to describe.)

Cousteau (talk) 16:12, 9 July 2017 (UTC)

Wait no; this other article links the 4.74 figure with 3.74 intermediaries, or 4.74 hops. —Cousteau (talk) 16:52, 9 July 2017 (UTC)
It has been done. Since the reference also reported the previous result of 4.74 as being 3.74, and explicitly uses the term "distance" to refer to 4.57 and not 3.57, it is clear that the change is correct, so I changed it. (Feel free to comment.) —Cousteau (talk) 17:11, 9 July 2017 (UTC)

Ramsey Theory

I believe "6 degrees of seperation" is related to the mathematical theory of Ramsey theory, where certain combinatoric structure necessarily emerges from systems. Pasting this comment here for people who want to elaborate on this.
