    I want to prompt for a value in the minibuffer and only accept the
    input if it matches one of the choices presented in my prompt string.
    How do I do this?

    (defun example()
      (interactive)
      (setq read_method(read-from-minibuffer "Read Method?
    [<,>,>>,+<,+>,+>>] " nil nil nil nil "<")))

You want `completing-read', not `read-from-minibuffer'. That will: 1) let
users complete their input to any of the possible values, and 2) require
that their input be one of those values. Use non-nil for the REQUIRE-MATCH
argument.
