Usually there would be so many people involved, it would be weird to send even a general thank-you and list out a set of people like you're accepting an Academy Award.
What's next? "I'd like to thank the
little people on the admissions committee—Karen, you're a real one! Thanks for answering that question I asked once in August! Also, I looked up Travis on the directory, I know you coordinated the Zoom rooms, big shout-out to you!"
Like, no, actually, allow me to physically prostrate on the ground before you on-camera to show you how deferential I feel.
In general, I find them kind of performative and insincere. I started the cycle sending them, and after the third clearly AI-slop response I received (after overthinking and overworking those thank-yous trying to rack my brain for the right words for hours), I got the picture.
And it makes sense, it's very unlikely some stressed third year working 60 hours, studying, and interviewing 10 different applicants on any given week is going to truly appreciate a thank you. Much less the overworked administrator who is used to the theatrics of admissions and gets a thousand love letters a day.
I say just stop accepting them. Why make it yet another stage for this play, another surface on which to project premed insecurities everywhere?
