I was on a podcast and the host used Positive Intelligence in the title. Do I need to have them change it?

Referring to the book is allowed, but using "POSITIVE INTELLIGENCE" as a title may be a trademark violation.

Possibly, we would have to look at precisely how it was used.

Everyone is free to refer to the title of our book in a descriptive sense, for example, to talk about the book. But using the words POSITIVE INTELLIGENCE as the title of any work could be a trademark violation.
