Depends on your POV. "How can we make the product better?" is usually synonymous with "What do users want?", which, following the rabbit hole down enough, you reach those psych things. Look at all the terrible gamification implementations. These are responses to seeing a certain pattern in design, but they're not backed up with any real idea as to why users seem to respond (I'll avoid using the word like) to these systems, and they usually suck. Knowing exactly why one strategy is good and why one is poor can help create a better product.
