I’m just spitballing here because the information is of necessity limited. To flesh out his interests, you might want to consider having him fill out a Myers-Briggs questionnaire and see what fit is suggested by that. There are lots of short form questionnaires available on line.
He sounds to me like someone whose strengths are defined by creativity and curiosity, as someone who is good at seeing patterns and connections between and among disparate elements. As such, he can probably be successful with anything that piques his interest. Therein lies the problem; interests change. So his career path might lie in fields which are project oriented and provide the flexibility to change from one thing to another, such as consulting. Counseling and people management offer some of these same advantages.
For a college major, I’ll offer 4 examples of approaches more than majors with which I think he might thrive.
First is the “Organizing Theme” major at Union College (NY). Read it on their website and see what you think. Union College has the advantage of being one of the rare liberal arts colleges which includes a mature department of engineering. (They’ve been teaching engineering at Union since 1845.) STEM majors at Union are encouraged to combine their STEM program with another major or minor in the arts, humanities, or social sciences.
Second is the approach at Connecticut College. They organize each student’s 4 year experience around an organizing theme, which they call “Connections”. Within that, they then help students identify “integrative pathways” to pursue a major area of interest. Again, read about it on their website and see what you think about it as a fit for him.
Third is the program at Babson College. Known as a business school, Babson combines both business and the liberal arts. Their required courses are half of each. Their approach to learning is hands on (start & run your own business as a freshman), collaborative, and team oriented. Instead of majors, they do “concentrations”. Read about it on their website and see what you think.
Fourth is the highly individualized approach at Grinnell College. I’m unable to describe it in just 2-3 sentences, so I suggest that you visit their website and see what you think.
These are examples and there are lots more unique approaches out there to help students realize their potential. What these 4 have in common is that they work with students to provide them with experiences to explore the patterns and connections between and among disparate elements. They engage students’ creativity and curiosity. If that sounds like your son, then I suggest that you look for programs like these rather than traditional majors.
I’m just playing a hunch here because I don’t know your son, but I hope this helps.
I wish you good fortune in your explorations.
