Equipment Reviews: Best Cutting Boards -- America's Test Kitchen, 2013, 3:10 -- https://youtu.be/lPyhS2LX_Co
I've been looking for a way to incorporate America's Test Kitchen into my classes and believe their equipment reviews are an excellent example of competing sources of knowledge.
From my own experience, every cutting board I've ever owned cracked and warped. Although I must admit I bought these cheap, experience would tell me to purchase the thickest, heaviest board available. My intuition tells me a different truth. If I was interested in purchasing a new cutting board, I would be attracted to the most vibrant colors and the sexiest design. Intuition also tells me that the most expensive board would be the best board. Tradition tells me a different truth as well. I can vaguely remember the cutting board my parent's owned and if I wanted traditional advice, I can call my parents and ask for their suggestion as to the best board. But a scientific approach to "the best cutting board" reveals a different truth than these former sources of knowledge. Gadget Guru Lisa McManus shows us her sample, method, and results from testing a variety of cutting boards, and the winner of this evidence-based approach differs from what my experience, intuition, and tradition would tell me. The best cutting board isn't the heaviest, sexiest, or most expensive, and the video above proves this with empirical data and methodological transparency. Another video that works with these 4 competing sources of truth is their review of collanders.
