This article discusses the relevance of delusions for a finding of criminal insanity. The authors start from the recognition that the psychiatric notion of delusion is considered relevant to criminal insanity in most jurisdictions and therefore integrates psychiatric perspectives to define delusions. The key focus is on the differences regarding how and why delusions matter legally between the Anglo-American and the Norwegian approach to criminal insanity.

Evolutionary arms races can lead to extremely specific and effective defense mechanisms, including venoms that deter predators by targeting nociceptive (pain-sensing) pathways. The venom of velvet ants (Hymenoptera: Mutillidae) is notoriously painful. It has been described as "Explosive and long lasting, you sound insane as you scream.

However, while identifying the discrimination perpetuated by the insanity doctrine, this article argues that the CRPD Committee has failed to uncover the ultimate source of disadvantage of which the doctrine is merely symptomatic. Instead, it is argued that the criminal justice system entrenches a notion of 'capacity-responsibility' which situates the mentally disabled defendant as the 'other'.

Article Synopsis
- Evolutionary arms races lead to specialized defense mechanisms in predator-prey interactions, with velvet ant venom being a prime example that induces extreme pain in would-be predators.
- Velvet ant venom targets specific pain-sensing pathways in a way that is efficient yet lower in toxicity, making it effective for deterring various vertebrate predators.
- The study revealed that a particular peptide in the venom, Do6a, activates insect nociceptors effectively but does not cause pain in mammals, indicating it may have evolved to specifically affect insect prey.
Psychiatric clinical diagnostic formulation has evolved over time. The changes alter our understanding and our ability to provide a public health perspective on the epidemiology of mental disorders in large populations. Epidemiology is an important perspective and set of tools to assess prevalence, treated prevalence, untreated prevalence, individual risks for mental disorders, and possible links to the etiology of disorders by following the trails of environmental exposures, biological measures, interpersonal dynamics, and genetic risk factors.
