What if most of what you learned about human behavior was built on a foundation that hasn't been properly tested? In 2015, a landmark project revealed that when 270 researchers attempted to replicate 100 of psychology's most celebrated studies, only 36% produced the same results. That isn't a minor footnote — it is a fundamental challenge to how we understand the science of the human mind.
In this episode of Second Thoughts, host Roger Hall — psychologist, behavioral expert, and author — sits down to unpack one of the most uncomfortable questions in modern science: how much of what we call psychological truth is actually just well-funded assumption?
Roger brings decades of clinical and research experience to a conversation that is equal parts eye-opening, practical, and surprisingly funny. From the hidden financial incentives driving academic fraud, to why ancient dietary traditions were solving public health problems centuries before double-blind studies existed, this episode will permanently change the way you read a headline, evaluate a study, and think about the wisdom passed down through generations.
π‘ What You Can Learn from This Episode:
πΉWhy 64% of landmark psychology studies failed to replicate
πΉHow traditions like kosher dietary laws were doing public health science long before labs existed
πΉThe real reason researchers commit fraud — and why most of them aren't even bad people
πΉWhat ego depletion is, why it makes sense, and why the study testing it was fundamentally flawed
πΉThe difference between a statistically significant result and one that actually matters in your life
πΉWhy "blind" peer review isn't really blind — and how academic politics kill honest research
πΉHow universities shifted from educating students to chasing million-dollar grants
πΉThe padlock theory: why accountability only works on certain kinds of people
πΉWhy discounting your grandmother's wisdom might be one of the biggest intellectual mistakes you can make
NOTABLE MOMENT:
"Did grandma run a double blind placebo controlled study? No. But we shouldn't discount the wisdom gained through centuries because we don't understand the explanation today." — Roger Hall
