Final answer:
Gianna made an assumption about the driver's behavior, which is a common psychological response when witnessing unusual actions. Assumptions about behaviors can be influenced by the observer's presence, especially if the observed individual is aware they are being watched, leading to changes in their actions.
Step-by-step explanation:
Gianna just made an assumption about the young woman's driving behavior. This hypothesis stems from observing behavior that deviates from the expected norm, prompting Gianna to speculate about the possible reasons behind it. The act of making assumptions can be influenced by a number of social and psychological factors, including context, past experiences, and societal norms.
It is critical that the observer be as unobtrusive and as inconspicuous as possible; otherwise, being aware of observation might lead to altered behaviors. For example, consider how one's driving behavior might change when they are aware of being followed by a police car in comparison to driving on a deserted highway alone. Similarly, Peter's frustration with a driver adhering to the speed limit, leading to his judgmental thought about 'DWE,' driving while elderly, also reflects how quickly we can make assessments based on limited observations.
