Many people grew suddenly rich, and others, not wishing to be left out, began speculating madly themselves. If this all sounds like the 'dotcom' bubble in the stock market at the end of the s, or the subprime mortgage credit bubble of the past few years, it's because the same psychological factors that Mackay first dissected so brilliantly in , and that were at work in Holland in the s, were behind those follies as well: greed, stupidity, the herd instinct, and a reckless belief that the old rules of economics were somehow repealed in this instance.
Of course tulipomania couldn't last, and it didn't. Mackay again: "At last, however, the more prudent began to see that this folly could not last for ever It was seen that somebody must lose fearfully in the end. As this conviction spread, prices fell, and never rose again. Confidence was destroyed, and a universal panic seized upon the dealers. A had agreed to download ten Sempers Augustines from B, at four thousand florins each, at six weeks after the signing of the contract.
B was ready with the flowers at the appointed time; but the price had fallen to three or four hundred florins, and A refused either to pay the difference or receive the tulips.
Defaulters were announced day after day in all the towns of Holland. Hundreds who, a few months previously, had begun to doubt that there was such a thing as poverty in the land, suddenly found themselves the possessors of a few bulbs, which nobody would download, even though they offered them at one quarter of the sums they had paid for them. Many who, for a brief season, had emerged from the humbler walks of life, were cast back into their original obscurity.
Substantial merchants were reduced almost to beggary, and many a representative of a noble line saw the fortunes of his house ruined beyond redemption. No wonder the book has never been out of print. Mackay wrote to warn people of the foolishness of the collective mind. His warning seems to me to be particularly relevant now, and not solely for economic reasons.
Everybody is probably familiar with the first, and best-known, manifestation of this phenomenon: Wikipedia. The name is a portmanteau of the words wiki a technology for creating collaborative websites and encyclopedia.
Wikipedia is a multilingual encyclopedia project supported by the nonprofit Wikimedia Foundation. Wikipedia's 10 million articles have been written collaboratively by volunteers around the world, and almost all of its articles can be edited by anyone who can access the Wikipedia website.
Launched in January by Jimmy Wales and Larry Sanger, it is currently the largest and most popular general reference work on the Internet. The idea of a free encyclopedia encompassing all subjects, written not by a panel of chosen experts but by teams of people interested in the subjects and subsequently updated and amended by anybody has been wildly popular but has also attracted much criticism.
Obviously, articles can, at least initially, have severe biases and inconsistencies. The question is whether in the end they get to the truth: does consensus produce something that is not just readable - most of the articles are pretty good in that regard - but reliable?
It turns out I have an entry in Wikipedia don't ask me who contributed it; I certainly didn't, and I haven't edited it either. If you do a Google search for my name, the Wikipedia article will be the second entry in the resulting list.
He is also the author of a monthly column in Genome Biology modeled after an amusing column in Current Biology penned by Sydney Brenner. Petsko is best known for using X-ray crystallography to solve important problems in protein function, including protein dynamics as a function of temperature and problems in mechanistic enzymology.
In my experience, Wikipedia is often inaccurate when it comes to scientific facts, variable but occasionally quite good when it comes to topics in history or politics, and absolutely first-rate on any matter of popular culture.
I suspect this reflects the interest of the Internet-savvy population as a whole, though I haven't done any surveys to find out.
I do know that every teacher warns his or her students not to trust it as an unconfirmed source of facts for term papers or theses; it would appear that the wisdom of crowds is not trustworthy without independent checking.
What does this have to do with genomics? Well, one of the most highly accessed articles in recent issues of Genome Biology was a piece by Barend Mons et al. By adding information to concepts in WikiProteins, scientists are invited to "expand an evolving knowledge base with facts, connections to other concepts, and reference information. Ideally, WikiProteins, which is still in the beta-testing stage, should contain both reliable information from experts and potential connections among data that haven't previously been noticed, or explored.
Here's an example, called up by me by searching for 'triose-phosphate isomerase', the name of an enzyme. I got a list of triosephosphate isomerases from many different organisms.
Clicking on the one from Escherichia coli gave me the following functional information: "isomerase activity Definition: Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. Doing a similar search for 'DJ-1', a gene involved in Parkinson's disease, produced after leaving out the hyphen : "Acts as a positive regulator of androgen receptor-dependent transcription.
