 So, one argument for the view that delusions are irrational comes from an examination of the relationship between the content of the delusion and the available evidence. Resistance to revising or abandoning the delusion in the face of powerful counterevidence or counterargument is a sign of irrationality: when we have delusions, we may ignore relevant evidence or attempt to defend our delusional beliefs from apparent objections with obvious confabulations. Often these attempts are deeply perplexing, and the reasons offered for believing the content of our delusions do not appear as be good reasons to others: in one of the examples of delusions offered at the start of this entry, a woman incorrectly believed that a man was in love with her and her evidence for that claim was that he was sending her secret love messages hidden in the license plates on cars of a certain state. However, the notion that delusions fail to be responsive to evidence has also been challenged: for instance, Flores 2021 convincingly argues that when we have delusions we have the capacity to respond to evidence that has a bearing on the content of the delusions, but other factors contribute to the fact that we resist counterevidence, such as motivational factors.
