I disagree. You do need to be talkative to be a good clinical doctor.. There are three reasons that come to mind: 1) You have to be able to carry a conversation with your patients in which you obtain history of present illness as well as background medical history to help arrive at a diagnosis (this is the most non-personal portion) 2) Very importantly, you need to be able to build a rapport with patients. 3) Also very important, you have to be able to get along well with all other colleagues and members of your "team." If nurses or techs dont like you, they are not going to want to deal with your. Believe me, there is nothing more difficult than a pissed off or annoyed staff that wont give you the time of day!
The ability to do these things is not necessarily correlated with being talkative "in real life." My dad is an excellent physician (this is not personal bias, but rather feedback I have gotten from his colleagues and most of all, patients and patient families who run up to me in the grocery store to tell me how much they LOVE my father.) And yet, he is VERY quiet in real life. When he is seeing patients, he is very able to ask them the questions he needs to ask and to establish a good rapport with them - they see him as a trustworthy, serious, and caring individual (which he is!), but he is uncomfortable in large groups, at parties, etc. He is great one-on-one and when he is talking about his passion: medicine. So I speak from personal experience when I say that if you can put aside your shyness in your physician role, that is more important than being able to socially emote and be talkative.
Many shy people are shy in social situations, but good doctoring isn't about being social, it's about being compassionate and able to elucidate findings from your patients. They're different, and many people with mild social phobia do just fine with patients and co-workers because the purpose is not to socialize, but to be a good physician.
And my father is not a pathologist, he is 100% clinician, and interacts with patients every day, 7 days a week. He does great.
Also, to address something else you said, being shy does not = being cold and impersonal. To the contrary, most shy individuals I know are highly sensitive and caring people who are just less outgoing than perhaps the average joe. I think it is far more cold to talk down to patients, be arrogant in your knowledge, and to be dismissive. Those things don't come with shyness -- they come with obnoxiousness!
As long as you can talk to patients, you'll be fine. Good luck.
