This chapter illuminates some of the hidden costs of the federal agencies’ use of automated legal guidance to explain the law to the public. It highlights the following features of these tools: they make statements that deviate from the formal law; they fail to provide notice to users about the accuracy and legal value of their statements; and they induce reliance in ways that impose inequitable burdens among different user populations. The chapter also considers how policymakers should weigh these costs against the benefits of automated legal guidance when contemplating whether to adopt, or increase, agencies’ use of these tools.
