UX Movement .... isn't a testing and research facility. It's just a blog.
The main culprit article over on UXMovement was this one about search button placement. At first glance it seems legitimate until you read the source page referenced, as well as the comments on the UXMovement article itself. IXDA picked up on this a few times and I don't want UX.StackExchange to link to pages that pretend (intentionally or not) to be research when they are only blog posts.
Some questions here on our site using UXMovement as a source:
Dashed underline on required fields (Answer)
Tap to hover and double-tap to click? (Question)
If we agree it's not an appropriate reference site we can determine a best course-of-action to take.
