and as far as answering these kind of questions go, its best to stay on middle ground, acknowledge both sides and seem about as sensible as you can about the topic....anyways i hope this helps and good luck on that interview!
good advice!
I was never asked about stem cells in any med school interviews, but i was asked in an interview by my premed committee. it was a pretty generic "what do you think about stem cell research" question. from what i can tell, stem cell questions and other "hot-topic" questions like abortion and assisted suicide, etc., are asked more to gauge a candidate's reaction more than his or her actual position on the topic. for instance, with stem-cells, the interviewers probably don't care
what you think about stem-cell research. they are probably more concerned with
how you answer.
if you say "golly, i think stem cell research is the best thing ever," without acknowledging that you understand why so many people take issue with it, then you're going to come across as insensitive. if you say "stem cell research should be outright banned," then you're going to come off as a fundie, anti-science hater. in each case, it's actually perfectly fine to have that belief, but you've got to temper it with a modicum of understanding for what makes the issue so heated.
regardless of your personal opinion, you've got to let the interviewer(s) know that you understand the spectrum of views on the issue, and you have to be able to defend your position while taking all that into account.
that noted, it's probably best to do a little research, figure out how you feel, and be able to logically justify that position. as long as you can explain why you feel a certain way, you'll probably be fine.
