Hollywood has given moviegoers many classic portrayals of grumpy old men. But new research suggests that getting older doesn’t necessarily make people cynical and suspicious. Instead, trust tends to increase as people age, a development that can be beneficial for well-being, according to two new large-scale studies by researchers at Northwestern University and the University at Buffalo.“When we think of old age, we often think of decline and loss,” said study co-author Claudia Haase, an assistant professor of Human Development and Social Policy at Northwestern’s School of Education and Social Policy.
