Solution 1:[1]

You have to format it like so:

*[_type == "post" && categories == "SOCIAL" in categories[]->title]{
  title,
  slug,
  body
}

If nothing shows up then there are no posts associated with that category. Categories are also case sensitive, so make sure your capitalization is right.

*[_type == "post" &&  "social" in categories[]->title]{
title
}
