Why does everyone default to rounded corners on buttons when the design brief clearly calls for sharp ones?

I keep seeing portfolios where people slap 8px radius on every clickable thing and it drove me crazy enough to ask a senior designer I clean for, who said rounded corners make action items feel softer and less urgent, but has anyone else noticed clients actually hate that when they want a clean, modern look?

I actually read this article from a UX researcher who studied eye tracking on buttons, and they found that sharp corners literally make people pause longer before clicking because your brain registers them as slightly threatening or formal. It makes sense when you think about it, like how warning signs use sharp angles but friendly things use curves. Your senior designer friend is right about the softer feel thing, but it's also a safety thing for the brain. If the client wants that clean modern look, they probably want the sharp corners to create that sense of urgency and high polish that rounded ones just don't give. I've seen this same debate come up in design groups where people argue it's just a trend, but the psychology behind it is pretty solid.

I remember seeing a talk from a designer at Google who said the same thing about sharp corners versus rounded ones. They tested it on their own buttons and found that people actually clicked faster on rounded ones because they felt safer and more approachable. The sharp corners made people take an extra half second to think about it, like their brain was checking if it was something dangerous. It's funny how something so small can change how we interact with a page. That client might be missing out on conversions if they go with sharp corners just for the look.

Notice this same thing playing out in how grocery stores arrange their aisles. The organic section uses softer lighting and rounded shelf edges to make you feel relaxed, while the discount store down the street has bright harsh lights and sharp metal shelves to keep you moving fast. Even in furniture, think about how rounded armchairs invite you to sit down while sharp edged modern couches make you want to stand. Small design details are literally nudging our brains all day without us even realizing it.
