The curse of knowledge makes experts terrible judges of their own work. Once you know how something works, you stop seeing what a new user sees and start filling in the gaps automatically.

pretty much

your brain hates blank space, so it fills it with the nearest sample: you

In 1989, economists Colin Camerer, George Loewenstein, and Martin Weber ran a set of experiments at Wharton.

think of it like designing a hotel room while standing in your own bedroom. everything feels obvious because you know where your socks are

annoyingly, no

asking helps, but the chapter is warning you about the gap between what feels true and what survives contact

In real teams, it usually goes like this. Designers review the flow and find it obvious. A developer reads the error message and it seems clear enough. The PM sits…

yep. what your context hides is the trap door

then it shows up as photoshop was built for experts

(1989).

make the hidden assumption visible before the review starts

then test the behavior, not just whether the room nods

and if a choice only works for informed, patient, caffeinated people, treat that as a bug

that’s the series tbh

design psychology is mostly noticing the human nonsense before it ships

deal. hydrate first
