You may have heard the question, “Do you support gay marriage?” or “Do you support same-sex marriage?”, and you may have given the time to answer it. If you are a person completely uninformed about this issue, and completely disconnected from it, then how would you answer this question? Would you say “yes” or “no”, or would you give a neutral and ambiguous answer?
The truth about answering this type of controversial question is that it is not really asking about whether you support same-sex marriage or not. It is merely a polite way to ask you a more loaded question: “Are you a bigot or not?” Answering “yes” or “no” can ruin your career or defame your reputation, depending on whom you answer. If you are answering this question wrongly to a Biblical literalist, then that person may think, “OMG! He’s/She’s deluded! He/She supports sin!” and then condemn you for it. If you are answering this question wrongly to a gay rights activist, then that person may think, “OMG! He/She is an anti-gay bigot!” and then tell everyone about it, so that everyone else will hate you and stop supporting you in your work, career, and personal life. The best, most cautious way to answer this type of question, I think, is to approach it in a neutral, ambiguous tone of voice; however, you must only do so, if you are uninformed, distant, and unaffected by this issue. That way, the voice or opinion will sound genuine, because your tone of voice matches your uncertainty about matters like these.
Another notable example would be abortion. Answering this question should use caution, as both sides, pro-life and pro-choice, can be very sentimental and opinionated about this issue.
What makes the work of a scientist difficult is that a scientist must do all of the above, when he or she wants to research in that field. That scientist must take a neutral stance, and find a method that is likely going to be peer-reviewed and criticized but provide results that could be falsified. A scientist should never use absolutes; a scientist should never say “prove”. Sure, a scientist can become a conservative or liberal activist, but its neutral position will be tarnished, and his words incredible. However, a scientist can find evidence that supports one side or the other, but never necessarily prove the validity of one side or the other.
In my humble opinion, I think neutrality is the best possible way to circumvent answering the actual question, if one is uninformed about it. Answering the question in an ambiguous or neutral manner is unlikely to get you pulverized or condemned. You may face some criticism, when you make an attempt to elude from the issue, but the critical consequences of neutrality are much more bearable to face than choosing the absolutes and adamantly adhering to them.
