Evolutionary Ideas
Sam Tatum
Sam Tatum's book, cited in Episode 148 for a study finding a banana-shaped warning cone 22 times more effective than a standard yellow safety cone at slowing pedestrians and reducing falls (see Banana-Peel Warning Cone Study), offered as evidence that the Red Sneakers Effect (Nonconformity Status Signal) and related distinctiveness principles apply to safety signage as much as to fashion or branding.
Cited again in Episode 166 for the London Underground elevator-lights example of operational transparency easing commuter stress (see Domino's Pizza Tracker Transparency Case).
Also cited (Episode 87, its first citation in this wiki, chronologically preceding 148/166) for the Shinkansen biomimicry origin story, and the Van Halen, Red Dead Redemption 2, Katz's Deli, café regulars-wall, and Octopus Energy signaling examples — see Costly Signaling.
