Epistemic Akrasia is complicated but describes the situation in which humans hold a belief even though they think it is irrational or unjustified.
The reasons why some hold these kind of beliefs is what identifies the akratic pattern of reasoning from other irrational ones:
More clearly it’s the weakness of will and the situations in which humans have all qualities, motives and opportunity to do something that they think would be right for them and fail to do so because they lack conviction aka will and so they give in to the temptation to do easier but less good actions.
Likewise when humans give in and adopt beliefs for epistemic akrasia, they do not want to perform those analytic and epistemically righteous judgments that would allow them to reject some beliefs because of a lack of proof or the presence of counter proofs to their evidence.
They hold on to ignorance as they form false beliefs or insufficiently motivated ones because it is convenient in some respects.
If humans choose not to think hard enough about what they believe, we can say that they may fall easily into a state of willful ignorance since this condition is broad and general enough to describe deliberate dismissal of adequate reasoning.
At the same time, it would be unfair to claim that also knowledge avoidance has a role in this process.
Humans who adopt epistemically akratic reasoning to form beliefs do not exactly know which kind of information, evidence and knowledge they are dismissing because they do not put enough effort into knowing that.
The akratic reasoning prevents them from precisely selecting which information they are dismissing, so they are not definitely in a condition of knowledge avoidance.
This then leads to self deception, that represents a challenge to the idea that knowledge avoidance is less involved in irrational beliefs and patterns of reasoning than willful ignorance.
