In 1985, thousands of blind taste tests showed that consumers preferred a new, sweeter formulation of Coca Cola. The company took this at face value, replacing the original Coca Cola with a new drink using the sweeter recipe. But the ensuing backlash to New Coke shows the limitations of objective thinking. Insiders forgot that, in the real world, people don’t consume drinks blindfolded. The data ignored the strength of the original Coca Cola brand.

Alfred Russel Wallace, codiscoverer of the theory of natural selection, advocated spiritualism and believed that nonmaterial forces explained the evolution of the human mind. Percival Lowell, a pioneer in planetary astronomy whose observations paved the way for the discovery of Pluto, was convinced that he had discovered martian canals of intelligent origin.

Richard Thaler & Cass Sunstein coined the term ‘Libertarian Paternalism’ in a 2003 article – a doctrine that aimed to guide people’s decisions without taking away their freedoms. It’s unlikely the idea would have caught on, had it not been for the much snappier title used for their 2008 book: ‘Nudge’ (interestingly a suggestion of one of the publishers who passed on the book)
