Both the reading passage and the lecturer delve into the usage of a brain scan lie detector, yet they present contrary perspectives. While the reading lecture claimes that brain scan lie detector more is accurate than the conventional polygraph, the lecturer challanges its effectiveness.

To start with, the lecturer argues that a brain scan lie detector could misclassify a true statement as a lie as people tend to suppress telling a imbarrassing story. Therefore, the brain scan conculde a statement as false while the subject might be just avoiding to tell a sensitive story. This casts doubt on the reading passage's argument that a brain scan does no misidentify a true statement as a lie.

On top of that, the lecturer explains that each of the individual's brain fuctions a little different. Therefore, there is no absolute cretria which leads to an inevitable interpretation of an expert. This opposes with the reading passage's explanation that brain scan lie detector is objective due to its no need for a subject analysis.

Finally, the lecturer contends that a brain scan is susceptible to trick its result and describes two possible methods. First, if the subject performs an intricate mathmatical process, the overall brain activity increases which allows the subject to mask its lie. Furthermore, if the subject claim a untruthful story and retell this story again, a brain scan is unable to discreminate this statement. This contradicts with the reading passage's contention that a brain scan is more difficult to deceive.
