The notion that science and technology interests are more common for thinking types then feelers is widely know. In many cases this is very much true but concerning INFJs I think this is a misconception. In many case INFJs can be even more interested in these kinds of subjects then thinking types and even more then our thinking type equivalent INTJs.
Looking at my my own interests they would definitely qualify for belonging to a thinking type even though I am an INFJ. I love science, biology, astronomy, programming, gadgets, technology, non fiction reading and much more. As a kid I used to screw apart electronics and other machines just to put them together again and figure out how they worked. I drew schematics and created inventions of my own. When I became older I studied programming and electrical engineering in high school, and I specifically excelled in programming which I was among the best in my school. Even beating the more theoretic and mathematical oriented students (math is good for programming) even though I sucked at math in itself. Still the arts always interested me the most and even though I am good at technical things, I ended up picking a creative job in graphics for my profession.
The notion that these kind of subjects only interests thinking types I think is very wrong. Thinking types tend to be more rational and logical in their thinking and therefore find things with these types of outcomes more appealing since they make sense for them. Thinking types of course have feeling functions as well to some regard, just as feeler types have thinking functions. When it comes to INFJs we have introverted intuition as our primary function which can also act rational and logical in it’s way of navigating and finding solutions to things. The difference is that instead of seeing just the logical solution like thinking types, we get to see it from all the other angles as well.
When it comes to picking your profession I think as an INFJ you should not turn away from thinking type professions just because you are primarily a feeler. In many ways it is only better because then you bring a whole set of different skills to the table that others do not, and you can also understand the rational and logical parts as needed. Being introverted intuition dominants we function on many different levels and we easily comprehend others systems since we are system builders at the core. This is one reason why people say that INFJs can seem to have multiple personalities and not just one, we adapt and learn because we approach everything at it’s core, and not only through an rational and logical lens. We are fluid learners.
