💎 On removing anxieties about buying a product (Dr Pepper)

But weirdly, I’ve never asked for Dr Pepper in a bar because you know they’re not going to have it and there’s that mild embarrassment about asking for something they haven’t got, and feeling like a bit of a twat. However, if you ask for Coke and they don’t have it, it’s their fault not yours, the whole dynamic’s completely different. The only place that it’s socially acceptable not to sell Coke is a total health farm weirdo place full of organic produce, and even then it’s a bit irritating. They’ll have loads of those Fentimans Victorian-style lemonades, and even then it’s a bit irritating—come on, just sell Coke for crying out loud! Everywhere else has to sell Coke and it’s their fault if they haven’t got it. An aversion to little things like minor forms of embarrassment stop me from being a maximiser and asking for Dr Pepper, and I’ll always ask for Diet coke if I’m in a pub or a bar unless they have some massive sign saying ‘We Sell Dr Pepper’, in which case I would obviously ask for Dr Pepper.

People are so good at distorting material to fit their expectations that the identical sketch was thought by each of nearly fifty subjects to apply specifically to him or her.

In addition to trying unconsciously to confirm his or her beliefs, anyone who pays to see a fortune teller will have invested time and money: unless he has just gone for a lark, he will therefore want to feel he has got something out of it (misplaced consistency) and hence will be predisposed to believe what he hears.

💎 On the value of operational transparency in product design

For example, the bright red Powerball in Finish dishwashing tablets, as well as the salient red centre of Anticol’s medicated throat lozenges, illustrates “this is the hardworking bit.” When we see these products there’s no question in our minds where the unique value or effort is. They’re practically radioactive. As Rory Sutherland writes in Alchemy, the same is true of striped toothpaste.’ Psychologically, the red, blue and white coloured stripes give us a clear signal that the toothpaste is performing more than one function, aiding the belief that this single toothpaste can offer the trifecta of strong teeth, fresh breath and …
