For some reason, Buzan’s “rules” or guidelines for developing optimal mind maps are controversial among mind mappers.
[Actually, it is quite apparent that the controversy stems from business competition or ego-driven claims by rival parties.]
Organic mind maps work best. Buzan’s guidelines are sound and quite consistent with current neuroscience.
People with dementia deserve to use the best methods to help address their cognitive difficulties. That’s why I prefer Buzan Organic Mind Mapping.
