Global North and South have clear definitions, but don't really match how we currently separate the different blocks.

For instance if we're addressing the amount of research on the autism spectrum or depression, I don't expect Russia or Australia to be significantly ahead of China or Brazil.

The same way putting Portugal and Brazil in different groups, but the UK and Australia in the same doesn't feel helpful.

There are many points in the article looking at colonization and Anglophony, these historical or cultural distinctions could be a better split perhaps IMHO. Or just embrace the complexity and not reuse any specific concept to group the countries they want to focus on.
