S4 E34 Why Smart People Keep Making This Mistake

Why do smart people search for evidence that confirms their beliefs instead of trying to prove themselves wrong? In this video, we explore Peter Wason's famous 2-4-6 experiment and the origins of confirmation bias. Paper: On the Failure to Eliminate Hypotheses in a Conceptual Task (1960) Author: P. C.

S4 E33 What Astrology, Personality Tests, and Soil Tests Have in Common

Why do generic soil reports feel surprisingly accurate? In this video, we explore the Forer Effect and discuss how vague, universally true statements can create the illusion of personalized insight—whether in personality tests, astrology, or soil analysis.

S4 E32 Bandwagon Appeal and Social Pressure

Why do people conform to group pressure even when they know the group is wrong? In this video, we explore Solomon Asch's landmark conformity study, Opinions and Social Pressure (1955), and reveal what his famous experiments teach us about social influence, peer pressure, independent thinking, and human psychology.

S4 E31 Dr. Jada Powlen - Summer Nitrogen on Tall Fescue?

Does summer nitrogen really make brown patch worse in tall fescue? In this interview, Dr. Jada Powlen discusses her 2024 study and explains why cultivar selection may be more important than nitrogen rate for managing brown patch disease. Paper: Brown patch severity of five tall fescue cultivars as influenced by summer nitrogen rates (2024) Authors: Jada S. Powlen, James P. Kerns, Michael A. Fidanza, and Cale A.

S4 E30 Does Manganese Influence Take-All Disease?

In this video, I break down the classic study “Optimizing Manganese Fertilization for the Suppression of Take-All Patch Disease on Creeping Bentgrass.” We examine whether manganese applications can suppress take-all patch, how application timing influences disease control, and why soil chemistry matters. The results showed that manganese fertilization significantly reduced take-all patch severity, especially when soil manganese availability was low. If you're interested in take-all patch management, manganese fertility, creeping bentgrass, and evidence-based turfgrass science, this is a must-watch discussion. #turfgrass #takeallpatch #manganese #soilscience #bentgrass #golfcoursemanagement #turfgrassscience  📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.
