Third person limited is, along with omniscient, likely the most common point of view. Third person limited is when the author follows only one character, and can get inside their head, their feelings, and their physicality while directly interpreting it. This is different from first person, which also only follows one person, because the author is allowed to explicitly interpret things for you. 

We learned briefly about the second person. Second person point of view is essentially addressing someone through your writing. It is written with "you are" and "you should" and it is one of the rarest points of view. Typically its only value is in essays when referring to your hypothetical audience. 

We learned recently about points of view in literary fiction. One of the most common types is first person, or the point of view of a character. The author speaks as the character and is written as "I did" or "We can." The limitations of only seeing through one character are often used in mystery or suspense plots to keep secrets and keep you guessing with the character.

Cognitive dissonance is when people think differently than others and those ideas clash. It can be constructive, and it can also be counter-productive. When people embrace the difference of ideas and attempt to learn from one another, the entire group tends to be strengthened. However, uncompromising ideas clashing in a group just leads to arguments, fighting, and occasionally, depending on groups, war. Cognitive dissonance is not really endorsed by your standard school or teacher. This makes its positive use difficult in our country, which could go a long way to explain or current political climate.
