Negativity bias decreases with age, according to Laura Carstensen (Stanford) and co-author
"Do You Look for the Negative Even When Good Things Happen?" - Psychology Today. 2/10/2019.
Interestingly, studies have also shown that for many of us, negativity bias decreases with age. According to Laura Carstensen and Marguerite DeLiema at Stanford University, “Relative to younger adults, older adults attend to and remember positive information more than negative information.” Based on two decades of research, they say that this shift, which they call the “positivity effect,” reflects a change in motivation as we get older, rather than a neural or cognitive decline.
