Why is there so much ignorance in the world today?…

Ignorance is a state of being uninformed (lack of knowledge). The word “ignorant” is an adjective describing a person in the state of being unaware and is often used as an insult. “Ignoramus” is commonly used in the UK and Ireland as a name of someone who is overwhelmingly ignorant.

Ignorance should be distinguished from stupidity although both can lead to “unwise” acts. Also, if important information is available, one may fail to acquire it due to lack of intelligence (not realizing its importance, or not understanding it). 

Does it seem like there is more ignorance today than there used to be? It does to me…

And is ignorance the reason for the growing lack of common sense?
