No doubt I’d have chosen biotechnology research. The field was not as developed when I was in college, plus I stupidly decided that a tiny liberal arts college was a perfect place to go to study physics.
I can’t think of many better fields that have the potential to help humanity in so many ways, to improve our soil, water, food, farms, families, health and way of life. Plus, it’s super interesting. If I accomplish anything as a social scientist it would be to fertilize the institutional and intellectual soils so that more people become interested in fields as such, that help consumers become more accepting of fields as such and to encourage entrepreneurship in fields as such. Enviropigs and peel-able pomegranates are barely surface scratchers.
