Wilful blindness is a critical concept in criminal law, particularly in establishing the mental state required for liability. The defining characteristic of wilful blindness is the deliberate decision to ignore certain facts or information that would otherwise indicate criminal wrongdoing. It involves a conscious choice to remain uninformed and not to investigate further, knowing that doing so might lead to the recognition of wrongdoing. This prevents individuals from claiming ignorance as a defense against criminal liability.

In this regard, engaging in risky behavior does not inherently reflect the intentional disregard for knowledge; it might involve unintentional factors rather than a conscious avoidance of information. Similarly, failing to seek legal advice could stem from negligence or a lack of awareness rather than an intentional choice to remain ignorant of relevant facts. A lack of prior knowledge suggests an absence of information rather than a conscious decision to overlook or ignore facts. Therefore, the concept of wilful blindness specifically emphasizes the deliberate act of ignoring obvious evidence, which is why that choice is the defining characteristic most closely associated with it.
