Robin Hanson:

Info Value = the added accuracy the markets provide relative to other mechanisms, times the value that accuracy can give in improved decisions, minus the cost of maintaining the markets, relative to the cost of other mechanisms.

A highly accurate market has little value if other mechanisms can provide similar accuracy at a lower cost, or if few substantial decisions are influenced by accurate forecasts on its topic.

Robin Hanson:

[&#8230-] I meant trying to field the highest value applications. That is naturally measured in accounting terms – value minus cost. Measures of popularity or familiarity would not at all be the same thing.

Robin Hanson:

[One should] try to offer a cost-benefit calculation. You could count how many employees had ever gone to a TQM meeting, but that wouldn&#8217-t tell you if TQM is valuable or not.

• Is BetFair Poker a booby trap for the gullible novices? Does The Sporting Exchange (the operator of the BetFair brands) help gangs plucking down innocent recreational poker players?? To get an inkling, don’t read The Guardian, seeded by the BetFair spin doctor- read Midas Oracle.
• The video that the technologically retarded BetFair spin doctor should watch.
