I absolutely love this podcast! It’s fun, informative, doesn’t go so deep that it gets boring but gives you plenty of insight if you want to do a deep dive on your own. Love the wide range of topics. My favorite podcast!

I love lots of podcasts, but some of them drive me crazy, because the host/narrator tends to drop in volume toward the end of a sentence, or uses a lot of vocal fry, or for whatever reason just is not a particularly clear speaker with a consistent cadence. I just found this podcast and was listening for about eight hours of a road trip, and Mike is one of the clearest and most consistent speakers I’ve ever heard. There are way too many very interesting topics that I just can’t get through because the narrator is hard to listen to. Mike is clear, consistent, good volume, good pacing, and a wonderful wide range of fascinating topics.

I’ve been listening to podcasts since 2009 and have my usual roster of favorites - radiolab, 99% invisible, this American life, how I built it - I don’t recall how i stumbled on this podcast but it’s quickly become a favorite ! I’m pleasantly surprised by the concise nature of the interviews, Mikes relatable style, the diversity in content, and so on. Genuinely grateful to add this to my roster and big appreciation to Mike and the team

I discovered this podcast during sequester. Mike Carruthers does an excellent job interviewing a variety of guests in a comfortable, professional manner. He keeps to topic and there's no "filler"-- topics are the focus. His professional experience and presentation is evident and engaging. I have learned about such a variety of things. Some on topics that I would never have thought to look into myself. I look forward to each episode. Thanks Mike!

Just tried listening for the first time and couldn’t make it past the half-way point. The way the host rudely talked over/at and dismissed the guest on the Good Friends episode that came out 2 days ago was off-putting and there were multiple sound editing errors. Seems like you have a lot of cool topics, but I won’t be listening again.
GetOutside23 · Jun 2024
I was excited to try a new podcast that hopefully explored intelligent topics and presented information scientifically, evidence based and unbiased. That is not what I got. The host is unbearably ignorant. As a interviewer it is imperative that you at least do a little bit of background research so you can talk intelligently but he continues to stifle the conversation with uneducated hot takes, and embarrassingly surface level questions. The questions he asks have no critical thinking involved AT ALL. A recent episode when discussing Americans being over worked, he failed to see the purpose of the guest’s argument and close-mindedly pushed back by continuously bringing up the ridiculous example of “what if people want to work” or what some LOVES their work?” How does that at all remotely further the conversation of forced productivity or over worked people? Ridiculous. Will not be listening to this show ever again. For intelligent content GO ELSEWHERE!
