Yes, I kind of bristled at the arrogant word "correct". Correct in what sense? What metric does the "correct" side boost over the "incorrect" one? How was correctness measured? Is it correct simply because it conforms to some document that some company wrote? Most of the choices to my eye are subjective and could go either way.

Then again, I'm not a UI designer. But I wonder what a UI designer thinks of someone boiling his/her design judgement down to a simple 'correct vs. incorrect' choice.

The "correct" would be just using different background. Hell, if you want to guide users put a gray background on skip option at least.

The page instead just makes it white, like it wasn't a button at all and we can only guess by the word only making sense for button
