Mm-hmm.

But when we look over the long term, we saw that these same individuals experienced faster functional decline over 10 years.

So that really kind of raised this question for us is what might explain why the effects of residential segregation are kind of mixed and might differ across individuals, with some people maybe faring pretty well in these environments, while others experience decline over time.

So rather than thinking about some people just being more resilient, we wanted to understand whether there are certain psychosocial factors that really change how people experience their neighborhood environment or might respond to these opportunities and challenges that they are presented with.

So one factor that we really got interested in was locus of control, and this is basically a person's belief about how much control they have over what happens in their life.

Someone with a high internal locus of control would tend to believe that their actions really matter, so things like exercising, staying mentally active, or taking care of their health could really make a difference in terms of their long-term outcomes.

In contrast, we have some people who have a higher external locus of control, and this is being more likely to believe that life outcomes are determined by outside forces, so things like luck, fate, or circumstances that are just really outside of control.

And I was curious about how you think about those kinds of influences shaping locus of control, and whether there ... areas that you're thinking about exploring in future work?
