Post-truthism, which devalues evidence-based reasoning, is not just a political issue but also affects First Amendment law. Compelled speech laws, where the State forces speech, are influenced by post-truth ideas, favoring certain types of information disclosure. For example, laws mandating disclosure of "uncontroversial" commercial information face less scrutiny than those for "controversial" information. This can limit access to trustworthy information, hindering the public's ability to seek truth and make informed decisions.
