Ask Marilyn: Is There a Fine Line Between Genius and Insanity?

Marilyn: Do you believe there is a fine line between genius and insanity? If so, can you explain why there is such a fine line?

Marilyn responds:

I don't believe extreme intelligence is correlated with mental illness in any way. However, personality traits found in certain highly creative people (for example, artists) have been linked with neuroses and psychoses.
