Ignorance is a lack of knowledge. Ignorance is sometimes misinterpreted as a synonym of stupidity, and is as thus often taken as an insult.In many cases ignorance is seen as a pleasant alternative to harsh reality.Willful ignorance (or vincible ignorance) is a bad faith decision to avoid becoming informed about something so as to avoid having to make undesirable decisions that such information might prompt.Ignorance is bliss is a phrase that comes from Thomas Gray's poem, "Ode on a Distant Prospect of Eton College" (1742): "Where ignorance is bliss, 'tis folly to be wise."
