I think I've seen this guy appear on at least a half dozen shows and podcasts including Lex, Tim Ferris, Sam Harris, Fresh Air, TED Radio, Hidden Brain... seems like 5 years or so ago he was everywhere. This site lists 67 appearances: https://www.owltail.com/people/Uw4Ky-matthew-walker/appearances https://www.owltail.com/people/Uw4Ky-matthew-walker/appearan... In general the media has very low science literacy and loves someone credentialed, self-assured, and with an erudite accent and story to tell that can easily fill airtime. Acknowledging that junk science has managed to platform itself on some of the podcasts you mentioned, for myself I'd say that the long-form format at least allows for a greater possibility that the b.s. will out itself over 1.5-2 hours, versus a show like TED Radio Hour that is happy to bundle up a few nice sounding stories into something they can slip a Blackrock ad into.
