The mnemonic mind map as a mirror of creativity. They obscure key words. This prevents the brain from making appropriate associations between the key concepts. They make it difficult to remember. Monotonous single colour notes are boring.
Most notes look like lists.
They waste time by encouraging or requiring unnecessary noting, reading and re-reading unnecessary notes, and searching for key words. They fail to stimulate the brain creatively. Linear presentations prevent the brain from making associations, thus counteracting creativity and memory. Alternatively, a mind map allows building on previous ideas, attributes, or stepping stone ideas. Mind maps use pictures.
