Here's your ONE drop:
Guinness says the perfect pint takes exactly 119.5 seconds to pour. Not two minutes. Not "about 120 seconds." 119.5 seconds exactly.
They could round. They don't. Because liars round. Experts measure.
When someone says "around two minutes," your brain hears guesswork. When they say "119.5 seconds," your brain hears stopwatches and lab coats.
The precision itself becomes proof.
This shows up everywhere once you notice it:
Guinness 119.5 seconds (not "2 minutes"). Real estate agents who spend 9 hours generate 36% higher quality ratings than those who spend 1 hour... even when they show the exact same houses. 4.9-star reviews outperform 5-star reviews because perfect feels fake...
You see it in pricing too. $99.47 feels researched. $100 feels made up.
The precision works whether it took you 10 hours to measure or 10 seconds to decide ".5" sounded official. Your brain buys it either way (though to be clear, this isn’t permission to make shit up. We have enough “data-driven” liars out there already).
But if you actually measured something, use the real number. All of it. Decimal points included.
And in case you wondered, yes, the Guinness thing is real. They've been perfecting that pour since the 1950s when a mathematician-turned-brewer named Michael Ash systematized the whole process. Most Irish bartenders don't follow it exactly, but that's beside the point.
