I heard about this study about this issue:
From alternative conceptions of honesty to alternative facts in communications by US politicians
"Communications by members of the US Congress on Twitter between 2011 and 2022, show that politicians’ conception of honesty has undergone a distinct shift, with authentic belief speaking that may be decoupled from evidence becoming more prominent and more differentiated from explicitly evidence-based fact speaking."
