nonresponder
Ignores all contact
A nonresponder is someone who fails to respond—to a survey, medical treatment, or other intervention.
In clinical trials, nonresponders show no improvement from a drug or therapy, contrasting with those who benefit: About thirty percent of patients were nonresponders to the medication.
Survey researchers track nonresponders to assess potential bias in their data.
