I see what you're saying, but this type of reasoning is still flawed. For example, I have a terrific group of friends. We have been close for years, and they were there for me when I needed them most. I judge them based on how they treat me, and others around them. Interestingly, not a single one of them takes part in volunteering. I also have never bothered to ask whether or not they took part in community service activities in their past. Why? It has absolutely no bearing on how I perceive them. Now, let's rewind back to my days as an ED volunteer. I remember an elderly volunteer came in early once during my shift (his shift was right after mine) because he just got back from a long vacation. He came in to make sure "everything in the ED was alright (because of course an ED would certainly fall apart without a volunteer)." During that time, he was acting very rudely and was bossing me around. At first I smiled, because I thought he was joking around. Then that awkward moment came when I realized he was dead serious about the things he was saying. Anyway, I wouldn't want this man to be my friend, and just because he volunteers doesn't mean that he is a good person.
Now I realize that as an ADCOM, you can't judge these applicants by other methods. Unless you have personally known someone for years, you won't know anything about them. I guess that's why ADCOMs must judge applicants by their ECs, which can be measured in a variety of ways. Hours, number of commitments, letters of recommendation, how applicants describe them in their personal statement, and how applicants describe them in the interview. But at the end of the day, whether or not someone does these things does not define who they are is a person. It's frustrating that it carries so much weight in the medical school application process, because often times you will have applicants strategically plan their activities to make themselves look better. You have applicants putting on a big facade to make themselves into someone they're not. In fact, I made a thread before about the paradoxical effect of many "great" ECs. If you have an applicant with stellar grades and a laundry-list of ECs, they are more likely to become future dermatologists, urologists, radiologists, and other competitive specialties. And how many of them will spend their weekends as physicians volunteering? I can't answer this, and it doesn't really matter. The point is that this "special" thing was turned into a box-checking exercise, and not just for pre-meds, but for other pre-professional students too. It's sad when people need to put on such a facade and tell others what they want to hear. Now I realize there are genuinely altruistic people out there who enjoy giving their time to others. But the vast number of pre-meds that engage in community service denigrates the meaning of it for everyone else. That's why I no longer care when I see someone's commitments in the WAMC thread or elsewhere. I just see it as someone else checking a box. And since I understand that volunteering is something people do because they want to, I don't judge anyone by their decision as to whether they do it or not. Instead I judge people by how they treat me and others.
