Downvoted for not providing a summary.

Here is my attempt at summarizing the quoted article:

• Personal guilt is defined as shame aimed inward

• Some cultures are based on guilt, others on shame

• One way to measure guilt might be murder rate [the author provides little justification for this]

• Another suggested metric is the corruption perception index. The author expects guilt-dominant cultures to have low corruption, and, unsurprisingly, finds the confirming evidence.

• Changeling tales are conjectured to be a tool to relieve the guilt a family feels over abandoning a sickly newborn. The author gives a long and rambling comparison of changeling tales from different cultures and eras, from ancient Greece to modern Africa.

• The author concludes with musings on genetic and cultural origins of the "guilt culture".

I must say that I have low confidence in amateurish research like this one, especially from a person proudly proclaiming "I actually believe in aliens and reincarnation". But it did make me think about guilt vs shame (and other cultural fictions controlling people behavior, like pride, honor etc.). Whether there is a reliable way to rate cultures by guilt prevalence and whether such a rating is an interesting metric remains to be seen. The author's case is certainly far from convincing.
