'Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity.' (Martin Luther King)

In my opinion, "sincere ignorance" and "conscientious stupidity" in this context is to become oblivious in terms of knowledge. Without knowledge, many things cannot be achieved.

“Ignorance” is referred to the lack of knowledge or education. Knowledge is comprised of 3 elements - Adversity Quotient(AQ), Emotional Quotient(EQ) and Intelligence Quotient(IQ). Adversity Quotient is the ability to cope with adversity, emotional quotient is the ability of self control and intelligence quotient is basically a measure for intelligence. If either of these is missing, there is only ignorance. Knowledge does not necessarily have a direct relationship with intelligence or wisdom. To be knowledgeable is not only to be smart but it is also to be able to make the correct decisions in situations. Without knowledge, wrong choices are being made and that is the reason for its danger.

As Martin Luther has stated, “nothing is more dangerous than sincere ignorance”. Money cannot be earned without intelligence; friends cannot be made without self-control; survival in this society is impossible without the ability to cope with adversity. As you can see, knowledge is the only key to success; without knowledge, nothing can be done.
