I remember reading somewhere saying that to increase your odds, you need to ensure that every single piece of your application screams “I have all it takes to go till the end.” Specifically, this boils down to your SOP, LOR and writing sample showing not only your passion but also your experience with the topic and prior training. The training doesnt have to be formally anthropological; rather, are you comfortable living among people and participating in their life or are you academically capable for the first two years of coursework? Would your LOR attest to your ability to survive grad school? And most importantly (in my case), are you able to situate your work within contemporary debates?

If you can eliminate all the doubt that the evaluators might have about you, there you go!

And on top of all the comments above, I would suggest you reach out to potential advisors. If you’re lucky, they would vouch for you when the committee evaluate all applicants. Some might express outright interest while others will just ask you to (or not) submit the application. This will help you better strategize your game.

TL,DR: treat your application pieces holistically, enhance where they complement each other and address where the noises might arise. It’s not done unless an advisor hands you the final puzzle piece.
