Gun permits may be more effective than background checks alone at reducing firearm homicides

A study published in JAMA Network Open suggests that states with gun permit laws see firearm homicide rates 18% lower than those with universal background check policies alone. Gun permits are associated with decreases in firearm fatalities due to their ability to record lower-level crimes and update criminal databases more consistently.

Judging your own happiness could backfire

Researchers found that having concerns or judgments about one's own level of happiness were associated with lower well-being, due in part to greater negativity and disappointment about positive events. Thinking too much about one's own happiness could be related to fears about not measuring up or not being as happy as other people.
