I think you are correct. Laura Ingraham just interviewed a polygraph expert, who is now a professor and he said the same thing.
You need to ask specific questions, not general ones.
Polygraph expert Jeremiah P. Hanafin who conducted the test worked for the FBI at the Washington field office. He spent time in the Counter Intelligence Division, which is where Peter Strzok also worked. Christine Blasey Ford’s brother, Thomas Blasey worked with Strzok’s sister, Jill Strzok. It’s possible that Hanafin knew Peter Strzok as Strzok may have called on Hanafin’s polygraph expertise from time to time. Peter Strzok lives in Fairfax, Va. Hanafin’s office is in Arlington, Va. Hanafin administered the polygraph test to Ford at the Hilton Hotel, 1739 West Nursery Road, Linthicum Heights, MD 21090 on August 7, 2018. In her letter to Feinstein, Ford states she is on vacation on the Atlantic coast until August 7th, and that she will be back in California, and can be contacted after the 10th.
