We begin with:
1. The accusation is deceptive. It does not come from experiential memory and it is deliberately designed to deceive for political purpose.
2. The denial does not need to be "Reliable", nor does "Unreliable" indicate deception. This is basic Statement Analysis.
3. Judge Kavanaugh went well beyond the boundary and entered "moralizing." Does this mean he was deceptive?
Investigators who conduct interviews, know that many de facto innocent subjects will use the word "never" when there is no psychological engagement with the accusation. It may take a few questions to get them to issue a denial, but we do not conclude deception based upon the word "never."
Investigators frequently experience this and are skilled at recognizing it and asking appropriate follow up questions.
"I never shot anyone."
This is a true statement.
Concluding "deception indicated" with the word "never" will continually lead to error.
Sometimes a subject uses "never" because of a refusal to lie outright. We have other indicators of deception that we compile together. Lance Armstrong "never" used PEDs. Alone, this would not have been enough to conclude deception.
Sometimes a subject uses "never" and did not "do it."
By itself, it does not stand.
When the subject avoids a specific allegation with the word "never", we need other indicators in addition to this, to conclude deception.
Context is key. The psychological engagement with an accusation should bring a subject directly to an event, and allow him or her to issue a reliable denial.
An accusation based upon a decade will not do this.
