This should be labeled as if for entertainment purposes only. Expert opinions are often unchallenged, and thus can be interpreted as if fact. Host consistently asks leading questions of the listener, and only sometimes are all critical factors mentioned on a given topic.
This is not to say the host lies at all, he certainly does not, but he makes little effort to keep experts honest, whether during an interview or during narration, when they provide fuzzy or disproven data.
Even as a self-described progressive, I feel many episodes have an unfair, covert bias that defaults forward-thinking ideas as solutions. Unfortunately, the best episodes are usually the ones about historical occurrences and how they influenced us.
