Two Zoltáns, Gócza and Kollin are maintaining a superbly good webiste about UX-myths, uxmyths.com.
Given the excellent quality of the site, they list common mis-beliefs people have regarding websites and they thoroughly debunk them with references to actual measured information.
Just by reading their list we learn, that
- People don't read the text you post (myth #1)
- Navigation isn't about 3 clicks, it's about usability of the navigation (myth #2)
- People do scroll, on all devices (myth #3)
- Accessibility doesn't make your website look bad and is not difficult (myths #5 and #6)
- Having graphics, photos and icons won't help (myths #7, #8 and #13)
- IT'S ALWAYS ABOUT THE DETAILS! (myth #10)
- More choices make users confused (myths #12 and #23)
- You're nothing like your users and never will be! (myths #14, #24, #29 and #30)
- User experience is about how user feels your site (myth #27)
- Simple is not minimal is not clarity, they are three different things! (myths #25 and #34)
- ... aaaand many more
Go see all the studies, research and details in their site.
