subject to suggestion

“I identify with the dying patient, who is weak, vulnerable, subject to suggestion, coercion, seduction,” he told the New York Times in 1996.

“A person who has just suffered the trauma of losing a loved one in such circumstances may be under tremendous stress. She may be confused and easily subject to suggestion.”

Several studies indicate that unconscious bias, subject to suggestion, may be at play here.

Once in that state, the patients are subject, to "suggestion," and are obedient to the will of the hypnotizer.
