This is not the correct way of thinking about psychiatry. Psychiatry is a subspecialty medical field dealing, in this day and age, primarily with brain-based treatment for complex, co-morbid brain-based (but also socially causal) conditions. Most of the new and at times more lucrative treatments in psychiatry are ALL "biology" driven: injections, TMS, inhalers, infusions, etc. This trend will likely continue as this is the main driver of high profit margin healthcare in this country. On the whole the field is mainly driven by: 1) pharmaceutical/device industry. 2) NIMH/NIH biology focused research. 3) major academic departments which are very focused on neuroscience/biology. Systems design issues are still being funded/worked on, and are thought to be important. You can also think of community psychiatry as half neuroscience/pharmacology, half "practice management"/"quality improvement"/"integrated care management". Not saying this is "right", or "ethical", or the way "it should be". Just saying this is what it is.
I discourage people who are more interested in sociomedical sciences or strict psychology to go into psychiatry as the field has become at times "too biological". If you are more interested in that or public health, I'd suggest a residency in preventative medicine or occupational medicine, or even internal medicine/primary care.
A typical community psychiatry job (like if you work for a big hospital system) usually has very little "psychotherapy" work and you'd need to think more about the kidney and the liver and the heart and med interactions and pancreas and blood cells and yes the female reproductive cycle etc much more than some other subspecialty fields in medicine, like dermatology. Also, it used to be that psychiatrists do a lot more "social work", "care management", than a typical MD. However, the system is pushing generally a model where actual social workers do social work for efficiency related reasons.
