Why are Concerns automatically considered Goals?

In addition to Jim's answers, with which I agree, there is quite another aspect to this question.

Concerns and Goals are different story points, though there are similarities including sharing the same structural item, e.g. Obtaining or The Past, etc.

• Concerns are general areas in which the inequity is explored. In the Overall Story, for example, the Concern describes the broad area of general concern that all of the characters share. The expressions and explorations of the Concern will be different for each character or group of characters, but the nature of the concern will be the same. Concerns tend to focus more on Theme, which is why they are part of the throughline specific story points.

• Goals are specific expressions of the inequity in the throughline. In the Overall Story, for example, the (Story) Goal is a story point the objective characters all see and take sides on. The protagonist is for the OS Goal, the antagonist is against the OS Goal. Goals tend to focus more on Plot, which is why the Story Goal is a story point best grouped in the context of the Static Plot Points.

Then there is the matter in the software where the structural item that is the Overall Story Concern is always the Story Goal. This was done intentionally (see note below*). The main reason we did this was because most audiences identify the protagonist and antagonist and other characters found in the Overall Story throughline to be associated with the Story Goal.

You can make another throughline Concern appear to be the story goal by emphasizing the Concern in that throughline and de-emphasizing the Overall Story throughline in general. The audience may assume that the more prominent throughline's Concern is the Story Goal. More likely, they'll just see the emphasized Concern as the goal in that throughline, such as a Main Character goal, or a Relationship throughline goal.

So, while I would not suggest you think of Goals and Concerns as being the same, it is good to understand that they share structural bonds with the Dramatica model of story structure.

• Making the Story Goal the same structural item as the Overall Story Concern reflects a cultural bias we built into the software, intentionally, and is consistent with the general bias of the software. The bias to which I refer is that of the Western viewpoint, specifically that of the American male linear thinkers. We chose that bias because it is the predominant bias in the U.S. and most Western forms of storytelling. (There is much more behind this, but not for this topic.)
