Ignorance is a lack of knowledge.[1][2] The word ignorant is an adjective that describes a person in the state of being unaware, and can describe individuals who deliberately ignore or disregard important information or facts, or individuals who are unaware of important information or facts. Ignorance can appear in three different types: factual ignorance (absence of knowledge of some fact), objectual ignorance (unacquaintance with some object), and technical ignorance (absence of knowledge of how to do something).[3]

Reasons for ignorance

People do not experience instant gratification and therefore they do not invest time and effort in learning and developing. Eradicating ignorance completely from an individual’s life is an impossible task but reducing the gap can truly benefit the individual in a long term.[4]

Also, making the decision to remain ignorant by committing to an ideology despite scientific proof is a dangerous mindset that can inhibit an individual from discovering the truth and therefore developing as an individual.[5]

Ignorance can stifle learning, especially if the ignorant person believes it is not ignorant. A person who falsely believes it is knowledgeable, does not try to clarify its beliefs, but rather relies on the ignorant position. It may also reject valid but contrary information, neither realizing its importance nor understanding it. This concept is elucidated in Justin Kruger and David Dunning's work, "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments"[citation needed], otherwise known as the Dunning–Kruger effect.

Another reason why people are not able to obtain knowledge is inaccessibility to education. In some parts of the world, educational infrastructure is insufficient and therefore people are not able to seek for knowledge. The phenomenon can be observed widely in underdeveloped countries where many children either cannot afford to go to school or live too far from a school. On the other hand, in developed countries most children have access to a K12 education but once they graduate high school they encounter obstacles to pursue a higher education due to high costs. This lack of education can contribute to individuals not being able to practice critical thinking and seek for knowledge for themselves.
