Optimistic Versus Pessimistic Brains

People who think they can learn from their errors have a different brain reaction to making mistakes than people who think intelligence is fixed. The former group bounces back better. 

What's the Latest Development?


Whether you think you can learn from a mistake may influence your ability to make better decisions in the future, suggests a recent study to be published in Psychological Science. Researchers studied how the brain reacts to mistakes in two different groups of people: Those who think intelligence is malleable and those who think it is predetermined and fixed. By giving individuals a simple task in which it was easy to make a mistake, the researchers were able to see differences in the brain activity among the two groups of people. 

What's the Big Idea?

The differences in the cerebral reactions between the two groups of people translated to important behavioral differences: Individuals who thought of intelligence as malleable were more likely to bounce back from their errors and pay more attention to their behavior in the future. In short, they monitored themselves for mistakes while individuals who thought of intelligence as fixed were resigned to repeating the same errors in the future. The research could help show people that they can learn more by understanding how their brain reacts to mistakes.

Antimicrobial resistance is a growing threat to good health and well-being

Antimicrobial resistance is growing worldwide, rendering many "work horse" medicines ineffective. Without intervention, drug-resistant pathogens could lead to millions of deaths by 2050. Thankfully, companies like Pfizer are taking action.

  • Antimicrobial-resistant pathogens are one of the largest threats to global health today.
  • As we get older, our immune systems age, increasing our risk of life threatening infections. Without reliable antibiotics, life expectancy could decline for the first time in modern history.
  • If antibiotics become ineffective, common infections could result in hospitalization or even death. Life-saving interventions like cancer treatments and organ transplantation would become more difficult, more often resulting in death. Routine procedures would become hard to perform.
  • Without intervention, resistant pathogens could result in 10 million annual deaths by 2050.
  • By taking a multi-faceted approach—inclusive of adherence to good stewardship, surveillance and responsible manufacturing practices, as well as an emphasis on prevention and treatment—companies like Pfizer are fighting to help curb the spread.
