Why do we make sacrifices for our loved ones? Research tells us that our commitment is what motivates our willingness to sacrifice. Sacrifice, after all, is really about navigating a conflict of interest. We encounter these conflicts of interest when our own personal needs and goals are incompatible with those of our partner or our relationship overall (e.g., continuing to watch our favorite Netflix show vs. helping a partner prepare for a job interview). In order to sacrifice, we have to resist the gut-level urge to act selfishly and instead focus on the long-term benefits to our relationship.
