The Illusion of Choice

“ All the elements of the experience – colour, smell, even the packaging – contributed to our expectations and therefore the taste.

In the 1940s, psychologist Louis Cheskin served housewives margarine dyed yellow and labelled as butter, alongside butter dyed white and labelled as margarine. The diners disparaged the "margarine" — which was actually butter. Cheskin called this " sensation transference ": context, color, and packaging override the product itself. He recommended dyeing margarine yellow; within a decade it outsold butter — a lead held for 50 years. This book catalogues 16½ such biases. Wendy Wood's research found 43% of daily behavior is habitual, executed on autopilot. Since people are "cognitive misers" who ration their thinking, these psychological shortcuts quietly steer purchases, perceptions, and loyalty. Each bias is backed by peer-reviewed experiments and paired with commercial applications. TAKEAWAY 2

“ …small bits of friction – even in an important matter like our kids' education – have a disproportionate effect on our behaviour. ” e.style.display='none');if(typeof getContentsSections==='function')setTimeout(getContentsSections,50)" /> Most marketing pumps the accelerator. Kurt Lewin's force field analysis argues the bigger lever is removing barriers instead. A Columbia/Harvard study proved this: when parents had to visit a website to sign up for an educational text service, just 1% enrolled. Simplifying to a reply of "Start" raised it to 8%. Auto-enrolling parents hit 97%. Teachers predicted the gap would be 27 percentage points; the actual gap was 96. Even tiny frictions suppress demand. London's Bob Bob Ricard restaurant installed a "Press for Champagne" button at every table — eliminating the need to flag down a waiter — and now sells more champagne than any other UK restaurant. Conversely, restricting paracetamol pack sizes added friction that cut related overdose deaths by 43%. TAKEAWAY 3

“ The trigger gave the nebulous desire something to coalesce around. ” e.style.display='none');if(typeof getContentsSections==='function')setTimeout(getContentsSections,50)" /> Habits weaken at temporal landmarks. Katherine Milkman found gym visits jumped 33% at the start of a week and 47% after a new academic term. The West Midlands police timed reform letters to criminals' birthdays and saw response rates rise from 2.6% to 4.1%. You can even manufacture fresh starts: labeling March 20th as "first day of spring" instead of "third Thursday in March" tripled sign-up rates for goal reminders. Motivation alone rarely changes behavior. Sarah Milne found a motivational exercise leaflet barely moved the needle (38% exercised), but asking people to state when, where, and with whom they'd exercise pushed compliance to 91%. Pepsodent's legendary campaign didn't say "brush twice daily" — it…
