What you choose when nobody is making you

CAP 150 · Matching interests and work · about 560 words

Adults love asking teenagers what they want to be. It is a hard question, partly because most fifteen-year-olds have seen only a handful of jobs up close. A more useful place to start is a smaller question: what kinds of activities do you keep choosing when nobody makes you?

In 1959, the American psychologist John Holland published a theory built around that question. He argued that both people and work settings can be described by a few broad interest patterns, and that people tend to be more satisfied, and to stay longer, in work that fits their pattern. He laid the theory out most fully in his book Making Vocational Choices, and it still sits underneath many of the career surveys used in schools.

Holland named six types, often shortened to RIASEC from their first letters:

Realistic. Working with hands, tools, machines, plants, or animals. Building, fixing, and being outdoors. Examples: electrician, wildland firefighter, veterinary technician.

Investigative. Figuring out how things work through observation, analysis, and research. Examples: lab scientist, data analyst, physician.

Artistic. Creating and expressing ideas in open-ended settings with few fixed rules. Examples: graphic designer, writer, musician.

Social. Helping, teaching, coaching, or caring for people. Examples: teacher, nurse, counselor.

Enterprising. Leading, persuading, selling, and taking risks to reach a goal. Examples: business owner, sales manager, lawyer.

Conventional. Organizing information, following clear procedures, and keeping details accurate. Examples: accountant, logistics coordinator, medical records specialist.

Almost nobody is just one type. Holland described people with a short code made of their top two or three letters, in order. Someone who is SAI might be drawn to counseling, while someone who is RIC might enjoy surveying or engineering technology. Holland also arranged the six types around a hexagon in the order R, I, A, S, E, C. Types that sit next to each other, like Social and Enterprising, have more in common than types across from each other, like Artistic and Conventional. A code made of neighbors is common and usually easy to match with work. A code made of opposites is not wrong, but it may take more creativity to find a role that uses both sides.

You can get a rough read on your own code without any test. Look at the classes you pick when you have a choice, the clubs you stick with, what you do on a free Saturday, and which part of a group project you volunteer for. Look for patterns that repeat across different parts of your life, since one fun class is weaker evidence than years of the same kind of choice. Free tools such as the U.S. Department of Labor's O*NET Interest Profiler ask about sixty quick questions and then connect your results to real occupations, with information on pay and training.

Still, interests are a starting point, not a verdict. They say nothing about ability, and abilities grow with practice. A low score on a type is not a ban on that kind of work. Interests also shift, especially in the teen years and early twenties, as you try new things. A good career choice depends on what you value, what you are good at, what training costs, and what jobs exist where you want to live. Use your code to decide what to explore next, such as a job shadow, an elective, or a conversation with someone in the field, not to rule your future in or out.
