As we start to understand, and learn to measure, the capacities that underlie behavioural freedom, we can begin to put this natural free will on a scale. Paralleling the measurement of intelligence, we could call it the freedom quotient: FQ. Such a scale should give us new insights into the factors that hinder or enhance our efforts to shape our lives. In other words, FQ should tell us how free we are – and how we can become even more so. - aeon.co
