When talking about better marketing for a better world, there is a lot of ground we could cover. One big point is that the domain we pick to do our research in plays a big role on its impact. While we can keep our theory the same, we can make our research more powerful by picking choices tasks or contexts that have greater potential to resonate with people or to convince policy makers that our findings are important. If your theory calls for a study with choice task as the dependent variable, for example, you can choose a choice domain that is more important, such as healthcare options, over something that is equally as valid but less policy-relevant, such as grills.
