Final answer:
A reasonable argument for the idea that personality change is maladaptive includes adaptation to new environments, consistency in behavior, and increased flexibility.
Step-by-step explanation:
A reasonable argument for the idea that personality change is maladaptive is the concept of adaptation to new environments. When an organism is exposed to conditions that differ significantly from its natural environment, it is likely to be less well adapted to the new environment, leading to maladjustment and potentially negative effects on health. For example, if a highly introverted person suddenly finds themselves in a highly extroverted environment, they may struggle to adapt and experience stress and poor mental health.
In addition, consistency in behavior is also considered maladaptive. If a person's personality changes dramatically and frequently, it can lead to difficulties in forming stable relationships and maintaining social connections.
Increased flexibility, on the other hand, can be seen as an adaptive trait. Being able to adapt and adjust one's behavior in different situations can be beneficial in terms of navigating through life's challenges.
