You mean outside the entire advertising industry? Now you might argue that advertising companies are more focused on selling ads to clients than optimizing the ad experience for victims, but it's an entire sector of the economy focused on exploiting the poor decision-making abilities of humans.
Of course, as long as we have had enough understanding that we can affect others, there has been a demand for exploitation through bias.
I think the hope here is that we would create positions that allow BE to benefit others AND businesses by helping people make better decisions. It sounds a bit utopian, but it's certainly not impossible that everyone could benefit from people making decisions that are beneficial to their well-being.
