ok dumb question, what’s the deal with your mind lies to you?
The longer you work on something, the less clearly you see it. Familiarity, overconfidence, and false understanding make your own design feel better and clearer than it really is.
so the villain is... my brain trying to be helpful?
pretty much
your brain hates blank space, so it fills it with the nearest sample: you
In May 2009, Google announced Google Wave and the room loved it.
that feels rude but accurate
think of it like designing a hotel room while standing in your own bedroom. everything feels obvious because you know where your socks are
wait so the fix is just ‘ask users’?
annoyingly, no
asking helps, but the chapter is warning you about the gap between what feels true and what survives contact

ok that’s the part people skip
yep. it feels better because it feels easier is the trap door
then it shows up as what google wave looked like from the inside
Then Wave opened to 100,000 users in September 2009 and normal people hit a wall.
so what do i actually do differently on monday
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
painfully usable advice
that’s the series tbh
design psychology is mostly noticing the human nonsense before it ships
ok send me the next one after i recover
deal. hydrate first
