4 and 12 are identical. 14 has nothing to do with UX or UI. 15, 11, and 17 are the same. 18 is an excuse masquerading as a Law. From 11-18, it feels a lot of these are pulled in from some Tim Ferriss book or some generic self-help Seven Secrets of Highly Influential People. Perhaps it believes its 15th and 17th law so much that it thinks it can hide fluff in the middle of the list.
It establishes credibility with a lawsofux.com domain them then proceeds to wreck it by violating its 7th law. It does solidly prove its first law, that if you have a pretty enough site, everyone will believe it.
