Comments on: On Aggregating Information: Hayek, Blogging, and Beyond https://archives.lessig.org/?p=3024 2002-2015 Wed, 07 Mar 2007 17:33:06 +0000 hourly 1 https://wordpress.org/?v=5.7.2 By: Ken Rushinzky https://archives.lessig.org/?p=3024#comment-11091 Wed, 07 Mar 2007 17:33:06 +0000 http://lessig.org/blog/2005/07/on_aggregating_information_hay.html#comment-11091 True and valuable information is a collective good. Participating in providing the “input” that over time will provide valuable information is not costless. So, even with such instruments as wikis and blogs, there will be a fundamental free-rider problem and suboptimal provision of the good. Each transaction in the market is different (not an analogy), even though the market as such is a collective good.

Indeed, one of the amazing things about prices is how they discard nearly everything there is to know about something while retaining just exactly the bits needed to guide the behavior of diverse actors in the marketplace. Moreover, they do so auto parts in a way that is relatively automatic, in that the aggregation computation is emergent rather than under any individual’s explicit control (which is what makes markets such robust institutions in the face of intelligent, highly self-interested agents trying to game the outcome).

When I go to the grocery store, I have no desire to share my preference for fresh pineapples, but it happens anyway.

This means that Google is actually much closer to the price mechanism in terms of it’s information aggregation process, because the Google rankings emerge as a second order effect from the nature of links on the internet.

The market is so immense as to approach what I call “practical infinity,” the inability of a human being to fathom or even imagine its breadth. The net is the same. There isn’t a free market, but there are entrepreneurs who, within some framework acceptable to them, operate in relative freedom. The best of these know that the unfathomable will send them the unforseeable, they just don’t know what. They lack the hubris to see the system as closed. “Price” isn’t the only issue; there is also the question of discovering goods and services you didn’t know you needed before you entered the market.

By the same token, those who succeed in having a viable net experience, whether it be doing business, seeking information, conecting with other people, or what have you, take the same fresh approach. They greet the unforseeable on its own terms.

That’s a fascinating comment, but to draw on what Alan said in the first comment, what is a linker giving up? In my blog, I tend to link only rarely, perhaps because I’d like to both focus my readers’ attention on a small set of things, but perhaps because an out-link is competition for attention between myself and someone else?

You could do worse than look at Yochai Benkler’s piece on sharing nicely which touches on some of these issues: http://benkler.org/SharingNicely.html

You might think more about how the Wikimedia Foundation resembles a government central bank and how to structure things to avoid the negative effects Hayek expects from central bank operations.

Prices are aggregates, and as such one of their most important functions is to discard information; that is, they are a form of lossy compression. Indeed, one of the amazing things about prices is how they discard nearly everything there is to know about something while retaining just exactly the bits needed to guide the behavior of diverse actors in the marketplace. Moreover, they do so in a way that is relatively automatic, in that the aggregation computation is emergent rather than under any individual’s explicit control (which is what makes markets such robust institutions in the face of intelligent, highly self-interested agents trying to game the outcome). Blogs and wikis are also aggregators, and thus also lossy, but the aggregation/lossiness is under the deliberate control of the authors and shaped by the authors (albeit with varying success) towards particular ends of their choosing.

One might perhaps be able to speak of the economy (using that word very loosely) of links in the blogosphere in terms of a price analogy, in that individual links are under individual control while the wider universe of links is not. This might be a fruitful avenue for investigation (indeed, the impersonal nature of the larger universe of links on the web is one of the key phenomena that indexing services like Google exploit to extract useful information in the face of the self-interested behavior of web site operators).

I base that on ten years of online experience with nuggets (links/nodes) of subjects studied in schools and colleges. When a superior link of such a subject appears online before long it is found by everyone interested – and most importantly by the experts in its field. This is even better than the google effect. The experts on a particular small topic all use the same few links. Also, students of a topic flock to the best website for that topic. This does not apply in a big subjects like chemistry or history. But it does apply for granular topics like the table of chemical elements or the study of the Phrygians.
The students flock to this table of elements:

The world’s experts on the Phrygians are probably all linked here:

I am not totally sure what kind of information you are talking about. Are you talking about individual preferences that are aggregated by the Hayek-like price system (like in, e.g., the Googld Pagerank system) or are you talking about content that is produced by a dispersed set of people (like in, e.g., wikipedia)?

I am not sure whether the distinction is ultimately important, perhaps both categories can be translated into each other. But one difference could be that, at least under certain traditional assumptions, the creation of a preference by an individual does not depend or build upon the preferences of other individuals, whereas a wikipedia-like content production system crucially depends on building upon and changing already-existing information/content. So the kind of information that is produced in various systems could differ.
