HubDub failed miserably in trying to predict the very unpredictable Mashable Open Web Awards.

HubDub saw a big future for the Huffington Post (in the &#8220-Politics&#8221- category) and Digg (in the &#8220-Social News&#8221- category)&#8230- [*] &#8230- but, curiously, these big-shot websites didn&#8217-t make it through. That&#8217-s strange, since the other websites they were pitched against are far less popular. The Mashable readers have a knack for fresh startups, maybe &#8212-they didn&#8217-t vote for the already established websites.

Do browse the list of the remaining contenders (among them, HubDub :-D ). There are interesting websites, there.

[*]

Huffington Post = 38%

Digg = 47%

These probabilities will crash down to zero in the coming hours/days, as these 2 websites are now eliminated from the competition, going further.

Google vs. Prediction Markets – Which of the 2 will detect the flu, first?

An Irish research team hopes to make accurate forecasts of key public health indicators.

University College Cork (UCC) School of Medicine + Intrade

Dr Dylan Evans:

Prediction markets are [specialized], small-scale financial markets operated to predict future events. The idea is that the collected knowledge of many people, each with a different perspective, will be more accurate than an individual or small group or even experts.

When they have been used to predict the outcomes of political elections, prediction markets have been found to be more accurate than alternative methods of forecasting.

The obvious area to look at in the first instance is infectious disease, but we plan to extend our research into many other areas of public health. At the moment, people do not get data on infectious disease until it&#8217-s a couple of weeks out of date and we need to get it quicker.

My opinion:

  • To assess the benefits (if any) of the prediction markets used as forecasting tools for public health, researchers will have to compare them with the experts&#8230- and with the &#8220-Google Flu Trends&#8221- web service, which is entirely free of charge and free of advertising (being sponsored by the Google Foundation). Does not sound good for the prediction markets.
  • The irony is that it&#8217-s our prediction market researchers (David Pennock and his accomplices) who gave weight to this non-market tool. &#8212- Pennock = Treator &#8230-!!&#8230- [ :-D – Joke. ]

Are prediction markets on deaths and assassinations SOMETIMES acceptable?

BELOW IS THE CHART OF A SETTLED PREDICTION MARKET:

Will Patrick Swayze die before April 15, 2008?

It was settled on &#8220-no&#8221-.

HubDub CEO Nigel Eccles thinks that his traders &#8220-quickly came to the conclusion that the [early 2008] story [giving him 5 weeks to live] was bogus.&#8221- And Nigel Eccles asks, &#8220-Is this an example where a death pool prediction market is actually socially valuable?&#8221-

In my view:

  1. It&#8217-s the opinion makers external to HubDub who should decide this. If most people and/or lawmakers decide that prediction markets on deaths and assassinations are disgusting and unacceptable, then they should be pruned. We need goodwill towards the prediction markets if we want the real-money prediction markets to be legalized everywhere.
  2. Would Nigel Eccles accept a prediction market about when his wife (or kid) is going to die?
  3. Is there a social utility in knowing when exactly a celebrity is going to die (supposing that such a prediction market could be accurate)? For a head of state, a running politician, or a Justice, that information might have a value. However, in the case of a Hollywood celebrity, I don&#8217-t see where the value lays. A prediction market on the upcoming death of a celebrity would participate in that big, stupid circus that occurs today, with paparazzi and tabloids taking an importance that they shouldn&#8217-t have in the first place. Our youth would be better off browsing and betting on prediction markets about science and technology. We should elevate our global civilization. I don&#8217-t see any (social or individual) benefit about knowing in advance when exactly Patrick Swayze is going to die. I am scratching my head right now &#8212-and I still don&#8217-t see any reason why we should spend our precious time blogging on this issue, betting on that, or collecting probabilistic predictions on that. I just don&#8217-t. (If you have a counter argument, do publish a comment below.)
  4. The very best wishes to Patrick Swayze, by the way.
