a better translation for the expression "psychology is dead" Expressions such as psychology is dead in


  A cognitive scientist once told me that psychology is dead.


are examples of personification, in this case, to convey the idea that psychology is using an outdated paradigm to study how the brain works.

How should I translate that into Chinese? I once said to a relative of mine who speaks Chinese


  有个认知学家告诉过我，心理学已经死亡。


and he couldn't understand what I meant until I told him about the re-interpration of the Stanford marshmallow experiment.

So what are some better translation for the expression "psychology is dead"? An alternative I can thought of would be "心理学已经过时" but that would mean removing the figure of speech from the original expression, and I'd like to avoid that.
Friedrich Nietzsche: "Gott ist tot."


Well-known translation: 上帝已死。


  Stephen Hawking: "Philosophy is dead."


Well-known translation: 哲学已死。

Thus I believe the best translation for "Psychology is dead" should be 心理学已死。

PS: Of course, without context, one might hardly understand the meaning, but any other translation won't do either. So an idiom-like expression fits.
