Wow, I don't know why everyone is being so extreme and jumping straight into lying. I can definitely see multiple sides to certain complicated issues like healthcare reform, but I definitely lean a certain way and I don't want to be dismissed for having an opinion. If I find myself in a situation where I am on the opposite side of the issue, is it too risky to try to "engage in a healthy debate" and point out flaws in the interviewer's points and have a conversation? We can sit here and assume that adcoms are all rational people who simply value intelligence and different points of view, but we all know that's not true. By "pander" I was being slightly ironic and mostly mean playing the pros and cons game and giving no hint of my allegiance.
I don't think the interviewers will dislike you for having an opinion either for or against a status quo, but what does look bad can include the following...
1. Support your point but refuse to acknowledge the other side... this is apparent when weakly addressing rebuttal arguments, or brushing them off superficially in your answers without acknowledgement.
Ex. I can understand that there are some supporters of euthanasia, but clearly intentionally aiding or directly murdering patients far outweigh the potential autonomy patients may gain in their end of life care /s
2. Having a viewpoint you believe in so strongly that it comes off as "radical" (that doesn't look good for either side)
Ex. all pro-abortionists are murderers, all anti-abortionists violate human rights etc.... /s
3. Not understanding the other side at all....
Ex. I know that there are others that defend opinion X, but I don't get it /s
That said...... the interview is NOT a platform for you to debate your views aggressively...you are to demonstrate that you are a well rounded thinker, and that regardless of your views, they shouldn't hinder your abilities as a PROFESSIONAL. You need to take the emotions without reason completely out and not have them misguide you.
