In late 1950s cardiologists Meyer Friedman and R. H. Rosenman coined the term “Type A” and “Type B” personality types. Meyer and Rosenman said that Type A personalities are competitive in nature, they tend to become self-critical when they do mistakes. They strive toward goals and rarely have sense of joy in their efforts or accomplishments. Type A people experience a significant life imbalance.  This is characterized by a high work involvement. 

Comparatively type B people look like laid back individuals. They have the ability to relax, enjoy small undertakings and they like to enjoy the small things in life. Though, they too get stressed but rarely. B Type personalities are non-judgmental and tolerant people. They usually exhibit higher levels of satisfaction in life. They are aware of their abilities and work progressively for their goals. They enjoy their achievements. They are not too much stressed out to excel. They do get disappointed when they fall short of their goals, but they don’t get overwhelmed like A type. B type accepts failures more easily. They enjoy outings, games and contests. They participate in competitions and contests not for the sole objective of winning but for the love of the game. They are thoughtful and innovative. They allow themselves to explore and fail, if necessary.

In business organizations “Type A” personality will always be in demand because they are competitive, energetic, impatient, and are always under pressure to finish work in time. To a great extent type ‘A’ personalities are the most sought-for employees. However, a tremendous amount of work has been done by psychologists on the personality types and they have found that type ‘A’ is most prone to heart disease. They work overtime a great deal and rarely take vacations. They are labelled as “workaholics,” and “fastidious” people. Do you know A Type individuals are usually insecure? Their insecurity results in an alluring urge to constantly remind themselves and others of their achievements.

On the contrast type B individuals are not concerned with time or numbers or awards. They cannot work under stress. They are friendlier people. The Type B person finds it easier to express and receive affection because they are hassle free.

Type B personalities are often more balanced in social situations; they handle sticky situations more gracefully. They are less competitive, more patient, more mutual and happier to enjoy the moment. They are certainly better people to be around with. While type A brags and shows off, types B are as skilful at achieving their objectives in the end, but they do not make big noise.

Another research says that in the most progressive country in the world, America has 50% of the individuals who fall into the Type A category, 40% into the Type B category, and 10% are in C and D. This research was conducted for ten years and was conducted on 3,500 men indicated that Type A men have at least three times as much coronary heart disease as Type B’s.

Type C people are abiding perfectionists. Type C personality is invented by psychologist William Moulton Marston and the assessment tool was created by industrial psychologist Walter Vernon Clarke. The type C personality is one of the four behaviour types determined by the DISC personality assessment (Dominance, Influence, Steadiness and Compliance)

The Type C personality is similar to Type A, but with some noticeable differences. A key one is perfectionism. Type C people spend more time on the details and check work several times for accuracy. They value the importance of doing an excellent job. Unlike Type A people, Type C people are less aware of time. For this reason, they strive for excellence and perfection can mean that a task takes much longer than it needs to. They are consistent and reliable, and they rarely bend or break the rules. The aggressive or impatience of a Type A person is more likely to result in them bending, breaking or even changing the rules. They will challenge the status quo. Type C person will happily follow the rules, so they enjoy jobs and tasks that follow a set procedure or are about complying with rules, laws or procedures. Type C people are great to have in any safety critical roles.

Type C people like to go deep into studying and learning one subject. Rather than being good in lots of areas, they prefer to be an expert in one or two areas. They enjoy meaningful conversations with one or two people. They don’t enjoy superficial conversations and prefer to avoid conflicts with others, so as not to upset the status quo.

Type D personality was invented by Johan Denollet. Since the early 1990s, the Belgian psychologist Johan Denollet has been studying a set of personality traits known as the Type D stands for distressed personality. Type D people have a tendency towards negativity. However, Type D people have many positive aspects too.

They are warm people, very peaceful on the outside and sensitive to other people’s emotions. Type D people have a very realistic view of life. They like security and are fairly resilient. They love to help and give guidance. These people rarely give up and can be a source of wisdom to other people. However, it is type D people often feel isolated, lonely and negative. They experience more negative emotions than the other types, but won’t share those emotions with others, because they are afraid of rejection.

I conclude the world is made up of all types – A, B, C & D therefore it is beautiful.
