Rauch reframes taste from an innate gift into a muscle you develop by maximizing 'exposure hours' — deliberately tracking and increasing the time you spend watching people use your products and others'. The inertia is to stay inside your own head and assume everything works; exposure to the friction of real usage grounds and humbles you into better judgment.
Origin
Presented by Guillermo Rauch as one of Vercel's internal operating principles.
Core principles
- 01Taste is a skill you can develop, not a trait you are born with
- 02You systematically overrate how well your own products work
- 03Watching real usage — yours and competitors' — trains the judgment muscle
- 04Painful reality is more instructive than your assumptions
How to run it
- 1
Quantify your exposure
Track how many hours you actually spend watching people use your product and using rival products yourself, rather than assuming you already know.
Pro tip Rauch colors his calendar so a set share of meetings are customer meetings — roughly a third in a given week.
- 2
Put the product in front of a real person
Hand your product to someone else and watch them interact with it instead of relying on 'it worked on my machine.'
Pro tip Invite customers to demo live how they use the product to the exec team or whole company; you always discover an unknown pain point.
Watch out You will feel the pain of seeing your baby break in front of everyone — that discomfort is the point, not a failure.

Stay at (or define) the frontier
Continuously try lots of products and study emerging trends so your reference set stays current and you can push design forward.
In the wild
Rauch asks his team to color his calendar so he holds enough one-on-ones plus customer meetings; in customer meetings he tries to forget how features are built and just uses the products as a normal user, then works backwards from what he sees.
→ Roughly one-third of his meetings in the week were customer meetings, giving him a steady stream of grounded observations about real-world success and friction.
Common mistakes
Assuming it works because it works for you
Builders default to thinking everything is fine and fast because it ran on their machine; without watching others you never see where it actually breaks.
Treating taste as innate
Believing 'that person was born with taste' becomes an excuse not to do the reps of exposure that actually build the muscle.
Is it for you?
Best for
Founders, designers, and PMs who want to build product judgment and stop shipping based on internal assumptions
Not ideal for
Teams with no live users yet or those unwilling to sit through the discomfort of watching real usage
