A more interesting study would be to see how much more effective a $5000 robot seal would be vs. a $10 stuffed animal seal. In the last days of my dad’s dementia when he was in his final care facility for people like that, there were a lot of patients with baby dolls which they loved and cared for. None of them looked like they cost anywhere near $5000.
Criteria like housing prices, population density, and crime rates are often emphasized when people consider the desirability of living in an urban area. These “livability” factors are associated with higher life satisfaction, both directly (by making the lives of residents better) and indirectly (because more affluent and satisfied people live in these neighborhoods).
However, according to a recent PNAS paper, these livability factors can only account for two-thirds of the difference in life satisfaction, with a large portion of the difference being attributed to something more surprising: a match between personality and neighborhood. In London, personality traits cluster in different neighborhoods and contribute to the life satisfaction of the residents there.

A majority of people tend to take their own conclusions about things and project them onto others, equating what they think they need and want and believe into what other people need and want and believe. Happiness, as a transitive emotional state, is the most relative thing in the world to try to measure.
People tend to adapt and don’t want to live in an unsatisfied state. Mankind is a tribal creature, and tends to emulate the behaviors of others when in crowded situations (such as a large city like London) in order to “fit in”. Most people tend to stay in a relatively small geographical region and will then emulate the behaviors of that region. Not wanting to seem “outside the tribe” they may even think that they’re “happy”. It’s not that their personality influences where they live, or how happy they are there. At least not for most people, which is what the study concludes. It may well be that the opposite occurs due to man’s tribal nature.
