False consensus makes you think users think like you. They do not. Your preference feels like evidence because your brain keeps using itself as the sample size.

pretty much

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

In 1977, Lee Ross, David Greene, and Pamela House at Stanford ran a series of experiments on what they called the false consensus effect.

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 design reviews, it happens like this. Someone builds a navigation pattern that makes sense to them and then describes users who cannot find their way around as…

yep. false consensus in action is the trap door

then it shows up as what this costs

In 2011, Color launched with $41 million and a strange idea about photo sharing.

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
