The article is really badly written. There is no "control" group (per the actual paper). Just a group that was given a lesser intervention. The actual research paper is available, and while it suffers from a lack of a control group, it shows that there were indeed some pretty remarkable changes in the lives of participants, and that there were statistically significant differences between the low pay group and the high pay group (which... duh, $11,500 extra is going to make a huge difference). Of course, without a control group, it is pretty hard to say what the effect of the income is vs. other programs, self-help, external factors, etc. https://static1.squarespace.com/static/64f507a995b636019ef8853a/t/6671a15eec7a812dee108e7c/1718722914185/FINAL_DBIP+Year+One+Quantitative+Research+Report.pdf https://static1.squarespace.com/static/64f507a995b636019ef88...
