Hidden Brain used to be one of my very favorite podcasts, with Shankar Vedantam’s excellent questions guiding guests through intricate story-telling paths to reveal great truths. Unfortunately recently each episode seems to now be two, unrelated episodes smashed into one, making each one ridiculously long, and disjointed. Yes, it’s clear that the second half is a returning guest from a previous episode, but the fact that it’s attached to another, completely different episode is just confusing and frustrating. Each still a great show, but the current format of the episodes is long and frustrating, knocking my rating down from 5 stars to 4!
