I'll go with the Lord of the Rings books where it was said over your reference that wasn't written by Tolkien, thank you. Hobbits were more resistant to the effects of the rings. Gollum had the ring for 500 years. Bilbo for a long time as well. The men were corrupted almost immediately. Dwarves were also resistant also did not become wraiths.
Sure, but according to Tolkien there’s nothing biological to it:
I think in the end it depends on whether you consider "hobbits are free of the things that the ring preys on, that is its power of corruption" a trait of hobbits that makes them not as easily corruptible because, yeah, that's how the corrupting effects work. So... we might just be nitpicking here on terms.They are entirely without non-human powers, but are represented as being more in touch with 'nature' (the soil and other living things, plants and animals), and abnormally, for humans, free from ambition or greed of wealth.
