Imagine a betting pool on disputed science questions, where the current odds are treated as the current intellectual consensus. For example, people might bet on whether cold fusion will be used to produce power by the year 2020. Right now the odds would be fairly low - say 20-to-1 against. But as the results of new research became known, and if more people became convinced that cold fusion worked, the odds would rise. And if cold fusion became a reality by 2020, those early supporters would make a bundle. ...

The system could increase the public's interest and role in science, and betting odds could serve as a scientific barometer to guide mass media and public opinion.
