Ancient brain circuits light up so we can judge people on first impressions
The scans showed that two brain regions were involved in opinion-forming, the almond-shaped amygdala, which is linked to regulating emotions, and the posterior cingulate cortex, which is active in making financial decisions and putting values on the outcomes of situations.

Lottery Tickets and Credit Cards: The Dangers of an Irrational Brain
A paper in the Journal of Behavioral Decision Making was inspired by the empirical observation that the poor spend a disproportionate percentage of their income on lottery tickets. They conducted two experiments to examine whether making people feel poor makes them want to play the lottery.

Subjects were made to either feel relatively poor or relatively rich The group made to feel poor purchased twice as many lottery tickets (an average of 1.27) than those made to feel relatively wealthier (0.67 tickets, on average).

In the second experiment, we indirectly reminded participants that, while different income groups face unequal prospects when it comes to education, employment and housing, everyone has an equal chance to win the lottery. This reminder that the lottery is a kind of “social equalizer” also increased lottery tickets purchases. The group given this reminder purchased 1.31 tickets, on average, as compared with 0.54 for those not given such a reminder.
