What term describes a legal principle that applies when negligence and loss are obvious to anyone?

Res ipsa loquitur is a legal doctrine that translates to "the thing speaks for itself." This principle is applied in cases where the evidence of negligence is so clear that it does not require further explanation or detailed inquiry to establish a defendant's liability. Essentially, if an incident occurs that typically does not happen without negligence, and the negligence and resulting harm are evident to a layperson, this doctrine allows a case to be made without extensive proof of the standard of care being breached.

For example, if a surgical instrument is left inside a patient after a procedure, the obviousness of the negligence makes it unnecessary to provide further details on how that care fell below acceptable standards. The scenario clearly illustrates a failure in duty, and thus, res ipsa loquitur can facilitate a plaintiff’s case without delving into the complexities of medical malpractice.

The other terms listed do not pertain to negligence or legal principles. Caliper measurement relates to a method of measuring dimensions, anatomically programmed radiography refers to a technique in imaging, and the fundamental properties of X-rays concern physics and radiology rather than legal concepts.
