Universal basic income provides recurring cash payments to everyone with no strings attached.Wong Yu LiangThe top researcher for a major study on guaranteed basic income says the findings are "nuanced."The study, backed by Sam Altman, gave $1,000 a month to 1,000 low-income participants.Elizabeth Rhodes says while the study showed benefits, it's not a quick fix for economic insecurity.The lead researcher for Sam Altman's basic-income study says guaranteed no-strings payments are not a silver bullet for issues facing lower-income Americans.Elizabeth Rhodes, the research director for the Basic Income Project at Open Research, told Business Insider that while basic-income payments are "beneficial in many ways," the programs also have "clear limitations."Universal basic income, or UBI, typically refers to making recurring cash payments to all adults in a population, regardless of their wealth or employment status, and with no restrictions on how they spend the money.Rhodes headed up one of the largest studies in the space, which focused specifically on those on low incomes rather than making universal payments to adults across all economic demographics.
