<p>people do change their mind all the time, even here, which is why some people like HumBio. you can concentrate in anything from youth education to health policy to neuroscience to children's advocacy. as Senior said, this can lead to just as diverse a set of graduate programs. however, i wouldn't expect that many useful job-related skills to be acquired through the HumBio major - mostly just intellectual growth through classes. if you want job-related skills, i would say english, CS, engineering, and econ are the main job-track majors, but even they sometimes need a masters.</p>
<p>the reality is there are just not that many jobs that want people with just a bachelors in human biology. in my opinion, these will likely be the same jobs that take people with a BA in sociology, IR, psych, english, etc. (general skill jobs). if you want a decent paying job with just an undergrad degree (which i would consider ~50,000, but this number would seem ridiculous to most stanford students), this would probably suffice. for a well-paying job above that, i would recommend graduate school or an engineering major.</p>
<p>career counselors at Stanford often say that majors are very slightly related to eventual career paths. while this is true, i personally think it's because of a lack of planning or direction when the students chose the majors. they probably didn't consider what jobs, if any, actually related to their major, so when they graduated, they looked at jobs that would accept a wide variety of majors. this is part of a wider movement among institutions to promote less professional-track majors, so they instruct students to major in something they enjoy. (unfortunately, i think it's become a cycle of telling students to major in what they enjoy because previous students that they told weren't able to find a career in their majors)
