The researchers then found that happiness at a given time depended on the awards received recently. Those received over 10 rounds previously had little effect. But they also found that the expectations of the participants had an impact . For Robb Rutledge, lead author of the study, "we were surprised to discover how expectations were important in determining happiness" . For example, the failure to win anything decreased happiness if the other option was to gain 2 pounds, but increased if the other was to lose the same amount. "It is often said that you will be happier if your expectations are limited. We find that there is a form of truth to it: low expectations increase the likelihood that the result exceeds expectations " .

From these data, the researchers constructed a mathematical equation in which the happiness expressed by the participants is connected to the recently received awards and expectations. This equation had to predict how people declared themselves to be happy. To validate their model, they applied to 18,420 people worldwide with a mobile phone game. In this context, the equation can predict the state of happiness of the participants when they played on their devices, even if they only earned points and not money.
In addition, during the initial laboratory experiment, neural activity was measured in participants through functional MRI that was interested in a brain area specific: the striatum . Indeed, it has a lot of neurons to dopamine , a neurotransmitter involved in the reward system. From the results obtained, dopamine plays a role in determining the happiness felt.
This work may find applications medical: the fact mathematically predict subjective states, like happiness, can help doctors better understand and treat mood disorders.
