Mythology (in addition to what you call pseudoscience) is also used to coerce false confessions, I think. There was a time period when only priests were literate, and mythology was used to teach the peasaants "morals." So, mythology is no better than pseudoscience in eliciting "repentance" which seems to be the ultimate goal. In every way, Chris Watts is obstructing justice. He uses his body to blockade anyone from discovering the murderous rage he is hiding behind him. He goes into his house and opens the door for Coonrod, and the first thing he does is close the curtains in the kitchen so the light cannot shine in. The only way to find truth in his case is to find what truth is not.

Deborah,

To be sure, I think polygraphy should be completely abolished.  When public agencies embrace polygraphy (or other bogus lie detectors such as voice stress analysis), it puts them in the pernicious position of promoting public belief in pseudoscience.

What I do admire is the skill and care with which Tammy Lee and Grahm Coder, without threats, promises, or coercion, persuaded Christopher Lee Watts to tell the truth and provide new case facts that could be independently corroborated. I don't think it's reasonable to insist that public agencies never use guile when interrogating criminal suspects. But safeguards against the real risk of false and/or coerced confessions are also necessary, and we see that in the interrogation of Christopher Lee Watts.

Well thanks for clarifying that your idea of a "superb" examinations means the absence of coercion, and the fact the interview was recorded and available for public scrutiny. My idea of a "superb" examination would mean the absence of lies by law enforcement- whether it was Chris Watts or anyone else. Nietzsche said it best: "Lying to the people to make them moral is immoral." If we cannot trust law enforcement who can we trust? And it is pretty clear after witnessing these deceptive strategies by LE that LE cannot be trusted at all. 

On 15 August 2018, Colorado Bureau of Investigations (CBI) Agent Tammy Lee conducted a polygraph interrogation of Christopher Lee "Chris" Watts of Frederick, Colorado regarding the disappearance of his wife Shanann and daughters Bella and Celeste. She was joined in the post-test interrogation by FBI Special Agent Grahm Coder.

During a post-test interrogation in which Chris Watts' father was invited into the room to speak with him, Watts confessed to the killing of his wife and provided details of the crime that could be (and were) corroborated, included the location of the bodies of his wife and daughters. The entire interrogation was audio- and video-recorded, and over the past week the Weld County, Colorado District Attorney's office has released lightly-redacted copies of the video along with CBI Agent Tammy Lee's report (attached).

I've watched the entire video recording, which runs for over seven hours, and wow! Tammy Lee conducted a superb interrogation beginning with a lengthy pre-test phase in which she worked successfully to build rapport and get Watts talking to her, and continuing through the post-test phase, where she and Grahm Coder skillfully broke down Watts' defenses without any threats or even so much as raising their voices.

During the pre-test phase, Lee asked Watts whether he had researched the polygraph. He said he hadn't. But if Watts had researched polygraphy, for example, by reading The Lie Behind the Lie Detector, he might have easily beaten the polygraph "test" that Lee administered. (Also, had he researched polygraphy, he might have made the wiser choice not to speak with investigators and to retain legal counsel, instead).

Lee administered a so-called directed-lie "control" question "test," a format wherein the person being interrogated is instructed to answer certain questions untruthfully. This technique makes it especially easy for the subject to identify the "control" questions, which is otherwise (in so-called probable-lie "control" question "tests") perhaps the most difficult part of employing polygraph countermeasures (methods for passing or beating a polygraph "test").

During the pre-test phase, Lee introduced the various question types in groups, as is standard practice. The relevant questions were:

Next, Lee introduced the directed-lie "control" questions, which she instructed Watts to falsely answer "no":

Finally, Lee introduced the irrelevant questions, which she called "known truth" questions:

If Watts had been familiar with polygraph procedure and countermeasures (discussed in Chapter 3 & 4 of The Lie Behind the Lie Detector) he might have covertly augmented his reactions to the directed-lie questions, for example, by solving math problems in his head, or biting the side of his tongue, and thereby beaten the polygraph. Had Watts beaten the polygraph, it might have resulted in misdirection of the investigation to the extent that investigators actually believe in polygraphy, which is scientifically baseless.

In any event, Lee scored Watts' charts as "deception indicated" and proceeded with a "post-test" interrogation, during which Watts at first insisted he had not lied when confronted with the news that he had not passed the polygraph. But Watts' confidence slipped when FBI Special Agent Coder revealed that he knew that Watts had been having an extramarital affair with Nichol "Nikki" Kessinger, a fact that Watts had been concealing from investigators. Coder used a minimization technique of suggesting that maybe Watts' wife had done something to their children, and he did something to her because of that. Watts grasped at that straw of hope, admitting that he killed Shanann because she had (he alleged) strangled the children.

Watts pled guilty to the murders of his wife and children to avoid the death penalty and on 19 November 2018 was sentenced to life in prison.

Congratulations are due to Lee and Coder, who conducted an outstanding interrogation. Their example shows that coercive interrogation techniques are not necessary to obtain independently verifiable confessions to even the most serious of crimes, and that recording of interrogations is no hindrance, either. Indeed, the recordings strengthen the evidence of the confession they obtained. (Compare with the case of FBI Special Agent Jennifer Sullivan's unrecorded polygraph interrogation of Jamaico Tennison.)
