Not sure I agree with you.
I assume that you made your decision on the merits of the case. On the testimony you heard, the evidence you saw, and the law as explained by the judge. If so, I don't see that as bias, at all.
On the other hand, if you decided the case based on an attitude that doctors aren't guilty and people who try to sue them are always wrong, then you were guilty of bias. And you should have gotten yourself off the jury before you did any damage.
Again: I assume that you are in the prior category, and I mean no hidden insult.
