Common test for mental health understanding is biased, study finds. The National Institute for Mental Health recommends a test, called the Reading the Mind in the Eyes Task (RMET), for assessing a person's mental health understanding -- that is a patient's ability to understanding what other people are thinking and feeling. But there's a problem. Using data from more than 40,000 people, a new study concludes that the test is deeply flawed. It relies too heavily on a person's vocabulary, intelligence, and culturally-biased stimuli. Source 8b.
This is true, not everyone will have the same pattern everytime for the same situation. There are many kinds of people with different expressions for different things - which will make the study hard to complete.
