Universalism and unconditionality for cash benefits are the two distinctive features of universal basic income (UBI) — a periodic cash payment to all residents without work requirements or other obligations. Because UBI aims to provide cash benefits not just to the poor income groups but to all income levels, it is expected that universalism is associated with support for UBI. In addition, because UBI is against conditions and sanctions in exchange for cash benefits, it is expected that people in favor of unconditionality are more likely to support UBI. This paper examines whether these two features of basic income are reflected in public attitudes toward UBI. Analyses using the European Social Survey reveal that people in favor of selective and unconditional social benefits are significantly more likely to support UBI.
