Final answer:
Knowledge detection captures what people think and believe, while lie detection focuses on human behavior.
Step-by-step explanation:
Knowledge detection refers to the ability to determine whether a statement or claim is true or false based on evidence and facts. It involves evaluating the accuracy and validity of information by using reliable sources and critical thinking skills.
Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues.
The main thing that knowledge detection does better than lie detection is that it captures what people think and believe but not necessarily how they behave in real life.
This means that knowledge detection focuses on assessing the truthfulness and reliability of information, while lie detection focuses more on detecting deception and dishonesty in human behavior.
Today's deception detection generally combines behavioral psychology (i.e., human observation) and technology (i.e. polygraphs and artificial intelligence).
