Difference Between Pessimist and Realist

Pessimist vs Realist

What do you think if there is a glass half filled with water placed on a table in front of you? Is it half full or half empty? This is the classic question that is used to arrive at the attitude of a person and see if he is a pessimist or an optimist. But there is the third kind also who is known as the realist. Realist and pessimist are far apart on a continuum that has pessimist at one extreme and the optimist at the other extreme. There are many differences between a pessimist and a realist that will be talked about in this article.


A realist is an individual who is not bothered about the left or the right wing mentalities, and he sees things and concepts as they are around him. He is not the sort of person who would believe in hearsays and propaganda as he has his own view about things. These people are neither with the majority or the minority but take a decision or action based upon their understanding of the situation.

A realist is objective and scientific by nature and does not believe a thing until he has the facts. Most atheists and agnostics fall under this category of people as they do not believe in religion or deities just because their elders ask them to do so. It is hard to categorize a realist as either positive or negative as he understands both the positive as well as negative aspects of a situation and sizes up a situation accordingly.

A realist does not see only obstacles or opportunities amidst obstacles. He tries to be practical in all situations and does not act on his whims.


A pessimist is a person who has a negative outlook towards life and always expects undesirable outcomes. The proverbial pessimist is the one who thinks that the glass is half empty rather than being half full. A pessimist has a bleak outlook and believes that the world and the people surrounding him are all bad. In some cases, continued pessimist attitude leads to depression and require medication or therapy depending upon underlying causes. Pessimism is a trait that can be improved though it takes time and effort to convert a pessimist into an optimist or at least a realist.
