1) 5-3-1: A dependable tactic for two people choosing a restaurant or movie: one person picks five options, the other narrows the field to three, then the first person selects one. This “has saved me and my girlfriend from starving to death on more than one occasion”, writes one commenter at ask.metafilter.com. Hint: couples should agree in advance to use this rule, so that “whether or not to use 5-3-1” doesn’t become a dilemma itself.
2) Be a satisficer, not a maximiser: “Satisficing”, coined by the economist Herbert Simon, means not letting the best be the enemy of the good. But it’s more rigorous than that. Rather than trying to pick the best bed-and-breakfast, for example, decide first on the criteria that matter most – “near woodland”, “serves a great breakfast” and “in Wales”, perhaps – then select the first one you encounter that ticks all the boxes. This is far less exhausting, and may actually bring you closer to the “best”, by focusing your mind on what matters, rather than alluring advertising or other distractions.
3) The 37% Rule. This is for sequential choices, where each option must be accepted or rejected in turn – as in flat-hunting, where an option may vanish if you hesitate, or, say, choosing where to picnic while hiking (assuming you don’t want to retrace your steps). Provided you can estimate the total number of options – the number of flats you’re prepared to look at, the number of potential picnic spots – it’s a weird mathematical truth that your best bet is to reject the first 37% of them, then pick the first one that’s better than any of those first 37%. (If none is, pick the final one instead.) According to an article in Lecture Notes In Economics And Mathematical Systems, this can be applied to choosing a mate, too. But maybe that journal’s not the greatest place to look for dating tips.
