Captivated is not captive, and even if it is etymologically adjacent, most of the electorate did not expect to have to learn about stuff like econometrics ...
How was anybody captive? I didn't see a single campaign ad or watch a single rally, except for a couple of brief excerpts that I chose to.
You're missing the critical point: it's not about captive, it's just that this helps with the critical point, which is an expectation of learning taking place, rather than worldviews/prejudices confirmed.
