Doctor James Mackenzie a Scottish cardiologist invented the very first polygraph machine. This instrument was used to record pulse in continuous illustrated line.

This being said, James Mackenzie’s polygraph paved the path for many years of scientific and forensic work to come

science from Paul Eckman. The content of this analysis will focus on Season 1 episode 2 titled Moral Waiver.

results of the polygraph are never revealed. The agent (WHO???) tells Tommy that he failed the test, and whether or not this is true, the results mean nothing. If it were true that Tommy failed the test, it would not mean he had a hand in the crime; his failure could be attributed to the 40% error rate of polygraphs (Dowler, n.d.). On the other hand, if Ward did not fail the test, then the police lied to him in an attempt to get him to confess. What makes the use of the polygraph significant to Ward
