The government is seeking to understand the nation's happiness, or well being, by instigating a survey. Some have criticised the cost of such an initiative. The Interactive Democracy web site could ask people to complete questionnaires on this issue or any other and would be an efficient method given its low cost, potentially large sample size and demographic accuracy.

It's also interesting to note that, according to one academic survey, direct democracy enhances the happiness of the Swiss, presumably by giving them the feeling of greater control over their lives.
