Good point and cheers for a thoughtful reply. :) The article states that two private foundations paid out about $10 million to finance the pilot program. The city of Denver seems to have no direct investment in this program, but it’s unclear from the article. It states that State university students did data gathering during the project and paid up to $30.00 for each response from stipend recipients. Given the above, I would respectfully suggest that these self-reports exchanged for money may be biased, confirmation bias could be a huge factor. The university is the only entity that has released their findings so far, which means that the only metric we have is the pilot project director’s opinion that, to paraphrase, “It went so well, we need more funding!”
