Is Psychometric g a Myth?
- "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth
approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g

The New Biology
- Eric Schadt's quest to upend molecular biology and open source it. (via
100+ authoritative research sources that are available online.
Various topics, real info. Think of it as a kind of do-it-yourself AskMe, or you know, a research library.(via Making Light)
we may not know where they are - but here's where they've been...
An incredible amount of information - current and historical - well indexed and with about a billion options
for searching through it. pretty impressive for what is at least unofficially a quasi-federal government site
despite protestations to the contrary.
CIA Electronic Reading Room, thousands of formerly secret documents.
A much better resource now that it was some time ago. This is straight via MoFi
, but I found it so interesting I could not resist sharing it here as well for any researchers or people like me who are just curious (currently). Linked in a previous thread about something else but I think it deserved a mention of its own.
The Logic of Diversity
"A new book, The Wisdom of Crowds
] by The New Yorker
columnist James Surowiecki, has recently popularized the idea that groups can, in some ways, be smarter than their members, which is superficially similar to Page's results
. While Surowiecki gives many examples of what one might call collective cognition, where groups out-perform isolated individuals, he really has only one explanation for this phenomenon, based on one of his examples: jelly beans [...
] averaging together many independent, unbiased guesses gives a result that is probably closer to the truth than any one guess. While true — it's the central limit theorem
of statistics — it's far from being the only way in which diversity
can be beneficial in problem solving." (Three-Toed Sloth)
This is good
, an international not-for-profit organization of libraries, museums, and other research institutions, comes this incredibly useful research tool. Start with as vague a query as you like, it'll provide an ordered list of search limiters to help you zero in on the resources you need in a far more organic and rapid fashion than similar tools I've seen. An invaluable resource for students, librarians, and the curious.
Paging Winston Smith...
Not content with mere cynical doublespeak, the Bush Administration is now trying to shape government reports and research to agree with the President's beliefs: an EPA report omits a section on global warming for the first time in six years
; the Department of Health and Human Services is being "restructured," eliminating committees that were coming to conclusions at odds with the president's views
; and at the Department of Education, old studies that contradict the current administration's policies are being removed from the agency's web site
. When you add this trend to the administration's "permanent war," I suspect George Orwell is smiling somewhere...
Too Much Information?
Heavy information overload: the world's total yearly production of print, film, optical, and magnetic content would require roughly 1.5 billion gigabytes of storage. This is the equivalent of 250 megabytes per person for each man, woman, and child on earth.
