> … recent research has shown that there are underlying similarities that can be observed when large numbers of synesthetes are examined together.[1] For example, “A” is frequently red. But I don't think that is to the point where it could have practical applications. When I read associations that other people have (as in sibling threads), my spontaneous (stupid) reaction is often: “Oh no, they have it all wrong”. Many people have used synæsthesia in art, but it should be considered a source of inspiration at best, and not a “secret key” to universal æsthetics (compare with the golden ratio fallacy[2]). From my own experience, non-synæsthetes can easily become fascinated with synæsthesia, while actually, it's not that big a deal.
