I see why you omitted these details - sexism is more catchy when you neglect the whole story

Also:

Rosenhan ans his colleagues did not pretend to hear voices, they pretended to hear a ‘hollow thud’- something with no basis in psychology. From the get go they were offering the doctors and nurses a chance to deny them entry, but despite the fact that the thing they were faking wasn’t even a real symptom, they were all admitted.

That very day, the moment of their admission, they went back to acting normal. They went about their day as normally as possible, and waited to see if the staff of each hospital they were in would notice. They stopped reporting hearing the noise that got them admitted.

The staff never noticed.

Some of the patients did.

Despite this, all of them were eventually released, but none were declared sane on release. Some were in the hospital for 2 weeks, one remained for over 50 days.

What the study proved was that it became impossible to establish sane from insane in the setting of a mental hospital. To retest, after Rosenhan came forward with his findings, he told asylums all over the nation that they’d be doing the experiment again, but with more participants this time. After a certain period, he would ask the head doctors of the ‘targeted’ asylums which patients they believed were faking it.

All of the hospitals reported at least one person.

No one was actually sent in.
