What can affect the liability of a defendant if the plaintiff is hypersensitive?

The correct response highlights the principle that a defendant's liability can indeed be influenced by whether they were aware of the plaintiff's heightened sensitivity. If the defendant knew of the plaintiff's unique sensitivities and nevertheless engaged in conduct that was harmful, this knowledge can establish that the defendant acted with a certain level of negligence or intentional misconduct, as they should have considered the potential impact of their actions on the plaintiff.

This awareness of the plaintiff's hypersensitivity indicates that the defendant had a responsibility to adjust their behavior to avoid causing harm, thereby increasing the likelihood that the defendant could be found liable for the plaintiff's injury. Consequently, this awareness creates a standard of care that takes the plaintiff's specific condition into account, as opposed to merely applying a general reasonable person standard.

In contrast, knowledge of a plaintiff's heightened sensitivity significantly differs from scenarios where the defendant indiscriminately acted insensitively towards everyone, which would not establish specific liability toward an individual. Additionally, requiring the plaintiff to demonstrate normal tolerance or placing an obligation on the defendant to prove a lack of awareness of the plaintiff's sensitivity does not address the impact of awareness on liability, making these options less applicable in direct relevance to the question about hypersensitivity.
