An outcome is a collective goal of two or more actions involving multiple agents just if the actions are directed to this goal and this is not, or not just, a matter of each action being individually directed to that goal.

This section depends on you having studied some sections from a previous lecture:
An outcome is a collective goal of two or more actions involving multiple agents if it is an outcome to which those actions are directed where this is not, or not only, a matter of each action being directed to the outcome.
Can you give sufficient conditions for there to be a collective goal? Yes!
If there is a single outcome, G, such that
- Our actions are coordinated; and
- coordination of this type would normally increase the probability that G occurs.
then there is an outcome to which our actions are directed where this is not, or not only, a matter of each action being directed to that outcome, i.e. our actions have a collective goal.
Question for a theory of joint action: In virtue of what could two or more agents’ actions have a collective goal?
Your question will normally be answered in the question session associated with this lecture.
