Chosen Ignorance does not exist

"Chosen ignorance" is purely oxymoranic. Ignorance implies a lack of knowledge. Chosen ignorance implies that a person recognizes and has knowledge that there is another choice. Hence we run into a problem of contradiction. By "chosen ignorance" I assume people mean one of two things:
1) Purposeful 'ignorant'-seeming judgement and perceptions motivated by self-interest
       Ex: You slipped on an orange juice spill in a grocery store and bruised your tailbone. You want to sue for money, so you purposefully determine/perceive that, after a disagreement with an employee, the employee maliciously left the spill in the aisle in hopes that you would fall and hurt yourself
2) Ignorance due to ingrained cultural bias
        Ex: You have grown up being taught that anyone who does not look you in the eye is rude, and you should then treat them as such.  So when an employee at a hardware store doesn't look you in the eye when you ask him a question, you immediately complain to the manager about a rude employee. The thought that the employee might have a form of autism or an attachment disorder which makes eye contact uncomfortable does not even cross the individual's mind.

Either form of ignorance does not leave an excuse for a person's behavior. Nevertheless, understanding the reasoning behind someone's decisions and perceptions can be important in figuring out how to move forward. Maybe, for the person who is ignorant due to cultural bias, all they need is a lesson on the subjects of autism or attachment disorders, and then they can fix their judgement and their reactions to the situation. In contrast, the person who is purposefully ignorant due to self-centered goals, they might benefit/ change their behavior by meeting the employee face to face, learning how their actions have affected the employee, hopefully gain some empathy, and learn how they can achieve their goals even quicker/more effective by working with the employee, not against them.
Considering the sources of 'ignorance' is important to solve even larger issues we face today such as mass incarceration of African Americans in the United States or religious conflict across the globe.
