According to a recent article by Carol Dweck, in Current Directions in Psychological Science, personality traits can and do change.

For example, when people move from holding a belief that ability is fixed to endorsing a belief that ability can grow and improve then changes can be observed in personality traits such as conscientiousness and resilience.
