Final answer:
Profiling is considered sketchy due to its time-consuming nature, potential privacy invasion, and the challenges in capturing true behavior versus beliefs. It also faces issues with assessing the reliability of the data collected.
Step-by-step explanation:
Profiling can be seen as sketchy or problematic for several reasons. One concern is that it can be time consuming, requiring a significant investment of time to build profiles based on data that may not always be relevant or collected efficiently. Additionally, profiling often tries to capture what people think and believe, which does not necessarily reflect how they behave in real life. This can make the data less reliable in predicting or understanding real-world actions. Moreover, the process of profiling can be intrusive, invading privacy by gathering personal information, which can lead to concerns over data security and the potential for misuse. Another issue is the difficulty in assessing the truthfulness of the data collected, which questions the reliability of the profiles generated.
