Collective efficacy and interdisciplinary work

I studied as an interdisciplinary studies major in my undergraduate program, and while our research was incredibly individualized we studied and discussed group interdisciplinary research at length. Group research in general requires significant collective efficacy to achieve a goal, even regarding domain-specific topics; therefore, when broadening research to interdisciplinary realms it’s even more difficult to encourage building collective efficacy amongst people who may not know how to mesh/communicate their research interests. Even when it is necessary to have multiple perspectives to solve a particular issue or achieve a certain goal, the group must understand each other well in order to do this effectively.
Last week we discussed that the reason people have known about problems like climate change for so long and haven’t done anything about it is because they have very little collective efficacy to make a difference. I see this issue as an interdisciplinary one because it not only requires climate scientists to publish research, but it also requires advocates in fields of business, education, politics/law, and service in order to enact true change. However, if each of these fields possibly have personal/disciplinary interests in acting a certain way regarding issues like climate change, it is entirely reasonable that they would have low collective efficacy to work together to resolve the problems. Not only that, but it also takes collective efficacy of the general population as a whole to make these sorts of changes, and in a time when such collective efficacy is…timid at best, there is little surprise that such issues have not been resolved even with the physical resources to do so.
Is there truly a way to raise collective efficacy?
