For Jim and Richard "How Do We Fix It?" has been a great big learning experience.

From how to switch careers to the search for meaning and the importance of speaking to strangers, our guests have proposed many smart, practical solutions. And they've also challenged conventional wisdom.

Our podcast invites listeners to get into their discomfort zone as a way of being more receptive to change.  

Jim starts this show revealing what he learned from David McRaney, host of "You Are Not So Smart," - a podcast about psychology.  David told us about our deep attachment to confirmation bias - where most of us try to confirm our views, rather than challenging ourselves with an opposing hypothesis.  

As someone who admits he knows little about science, Richard says he has learned about the scientific method from several guests, including Ainissa Ramirez and Michael Shermer. In the lab, scientists routinely test and try to disprove a theory before they embrace it as fact.

Some Fix It episodes were ahead of the curve. John Gable, Joan Blades, Geoff Colon and other guests raised the alarm about filter bubbles and online information silos well before Mark Zuckerberg and other Silicon Valley executives voiced their concerns.

Last year, Megan McArdle, a columnist at Bloomberg View, spoke to us about the tangled problems of fixing Obamacare months before President Trump and House Republicans realized how hard it be to "repeal and replace" without a massive fight. 

We also heard from Steve Hilton, former personal advisor to British Prime Minister David Cameron.  He made the pro-European case for Brexit in a surprising and enlightened way.

Richard tells Jim: "I've learned a lot from you," declaring himself to be a "thorough convert" to Jim's conviction that we romanticize the past and catastrophize the present. Richard has also come over to Jim's view that the challenge to free speech on college campuses is a much more serious problem than many believe.
