Zombie Ideas Again: “The Learning Pyramid”


Stories, ideas, and beliefs that have been disproved through scientific studies litter the mind. Professionals across-the-board in medicine, law, architecture, engineering, and business take-for-granted stories that have little to no basis in evidence. Yet they persist.
In earlier posts, I have identified such “zombie” ideas that have scientific-crafted shafts buried in their heart yet arise again and again (see here and here).
