This chapter discusses how governments and supernational institutions have tried to tackle misinformation through laws and regulations. Some countries have adopted new legislation making the spread or creation of misinformation illegal; this has often been met with criticism by human rights organizations, for instance, because governments cannot act as neutral arbiters of truth. The UK and EU have adopted expansive regulatory frameworks that regulate not only misinformation but rather the online information space in its entirety. The United States is generally wary of any new legislation that imposes limits on speech, and doesn’t currently have legislative initiatives that are as broad in scope as those in the UK and EU. Instead, some entities in the US have tried out investing in communications campaigns about mis- and disinformation; these are aimed at individuals (and not companies or misinformation producers), and their effectiveness is evaluated in a very different way.
